The Functions Of the Bendix Diagnostic Software

As we have seen from the brief history and products of Bendix, their efforts are largely channeled towards safety systems in commercial vehicles such as trucks and trailers. These are very complex systems more so in today’s complex vehicles where the safety components are increasingly interconnected. Hence, it is essential that you know precisely what to check and where to check whenever a Diagnostic Trouble Code (DTC) pops up. 

What is DTC that checks the health of vehicle systems and warns drivers of any malfunction? Every modern vehicle today is fitted with an onboard computer with a display screen that is tucked below the dashboard on the driver’s side. Whenever a fault occurs with any system or component, a warning light flashes on the screen along with a DTC typically in an alpha-numeric format.

The light conveys a simple message – some fault in your truck requires attention and needs to be checked before any minor issue becomes a major problem leading to prolonged downtime. The first response to an indicated electronics problem might be to remove or replace components. But at times, components are not an issue, and it is here that the Bendix commercial vehicle system diagnostic software needs to be run to understand what is wrong with the vehicle and take quick corrective action.

When you are running the software by connecting the laptop to the onboard computer of the vehicle, there are several things that will show up. You will get a system view of what is wrong with the key vehicle components especially if more than one component indicates the presence of the same active fault codes. 

In many instances the DTCs are temporary in nature that is, by fixing a minor issue like a loose wire or clearing accumulated debris, the indicator warning lights will be deactivated. These fault codes are typically cleared within a few driving cycles but if not, the matter must be investigated further with an optimized Bendix diagnostic tool. It will bring the faulty truck back on the road and in good performing condition as quickly as possible. 

Before diagnosing a fault, it must be remembered that the various systems of a commercial vehicle are connected with one another. Multiple control units (ECUs) share necessary information over the J1939 network. For example, automated transmissions must get essential information from the engines if they are to run at peak operating efficiency.

Hence, before assuming that an active fault code in an advanced system means that there is a malfunction in the system, you must ensure that you are using a tool that gives overall visibility of the entire system and components. One such tool is the Bendix Acom diagnostics software which shows the fault codes of the entire vehicle.

It is interesting to learn what Brian Screeton, Bendix supervisor – Technical Service Training has to say in this regard. “A tool that shows you an active DTC on the engine retarder, for instance, tells you that you need to troubleshoot that issue first, because it may be the cause of your adaptive cruise control DTC. In fact, we recommend technicians always troubleshoot any active engine faults first because of the way they impact other system faults.”

When the ACom diagnostics software is used, it automatically identifies and collects all fault codes from Bendix electronic control units on the vehicle, regardless of whether the DTCs are active or inactive. These include critical vehicle systems such as the engines, transmissions, and more.

The advantage of using the Bendix diagnostic tool is that you get precise information about what is wrong with the truck instead of wasting time falling back on guesswork from a prepopulated list of components.

The Need for An All-Round Diagnostic Software

As we have seen, modern trucks have complex systems that are interconnected. While Bendix provides specialized components, there are several others that are not from this brand but act as a critical part of running those from Bendix. Hence, to check on the overall health of a truck, you need diagnostic software that includes all systems and components. This is where our Jaltest diagnostic software for commercial vehicles comes in very handy.

The Jaltest maintenance tool is ideally suited for a wide range of commercial vehicles and offers advanced and cutting-edge solutions. It provides maintenance data, vehicle data, injector coding, VGT (Variable Geometry Turbocharger), and more. Even when a component has to be changed, the software offers replacement guides and will help you navigate through the process so that optimized resolutions may be implemented.

Additionally, there are several maintenance solutions that are handled by our Jaltest software. You can actuate body components, calibrate VGT and code injectors, calibrate transmissions, get wiring diagrams, technical information, component replacement instructions, repair times, and more. From simple fault code clearance to complex ones such as forced regens, system checks, parameter settings, calibrations, and others, the Jaltest software has you covered.  

When it comes to resolving fault codes of heavy or medium-duty trucks and semi-trucks in combination with the Bendix ABS diagnostic tool, Jaltest is a leader in the field. This is because diagnosis is made easy through live technical data and information along with detailed wiring diagrams to pinpoint the location of the fault. 

With the tool, you can set parameters for critical activities like speed limits and idle speeds, code injectors, and bleed braking systems for all types and makes of semi-trucks. Also available are system scans such as after-treatment and other resolutions for antitheft, brakes, electronic control modules, engines, hybrid systems, safety, and transmissions.

Capabilities of the Bendix Diagnostic Software

The Bendix diagnostic tool is an all-inclusive diagnostic tool that covers all Bendix electronic systems and ECUs. It offers support for Bendix ABS, Bendix ESP, Wingman Fusion, SmarTire, Intellipark, GSBC, GSAT and many more. 

To get the best out of the Bendix diagnostic software, integrate the OEM tool into the Jaltest software for a seamless experience. This allows former ACom PRO subscribers an easy upgrade since Bendix ACom diagnostics replaces it as of September 1st, 2024 provided the Jaltest license is active. If you need to renew your ACom PRO license, you must purchase the new ACom AE license as the previous Bendix Acom diagnostics tool is no longer available. 

Here are some of the key benefits of the amalgamation of the Jaltest and the Bendix commercial vehicle system software.

• You can generate Bendix OEM DTC reports for comprehensive diagnostics and access Bendix-exclusive service data sheets and technical information for accurate and reliable maintenance.
• Get expanded coverage with an OEM interface since Jaltest users won’t need to purchase any additional adapter to work with Bendix ACom when using the Jaltest v9 Link.
• Additionally, ACom AE enables parameter modifications on trailers, supports SLC25 anti-collision systems, GSBC, GSAT, and end-of-line trailer testing. 
  

Bendix Trailer ABS Diagnostic Tool

Trailers play a major role in the commercial vehicle landscape in the USA and one of the critical systems connected with trailers is the anti-lock braking system (ABS), It is an electronic system that ensures that a trailer is stable and steers well while braking. For example, if hard brakes are applied especially on wet and slippery roads, ABS prevents the wheels from locking up.

When the auxiliary circuit is first powered on, the ABS runs a self-check and the status light comes on after 3 to 5 seconds. If that does not happen, it indicates a fault that must be identified with the Bendix trailer ABS diagnostic tool. 

Summing Up

With the Bendix diagnostic tool, you can carry out full system scans periodically to check the health of the systems and components such as the Bendix active safety technologies, vehicle dynamic systems, air supply and air management solutions, steering solutions, trailer solutions, and more. Any fault even of a temporary nature is thereby quickly identified and the fault cleared before it becomes a major problem. 

This preventive maintenance program undertaken at regular intervals will keep your commercial vehicles on the road without downtime and get maximum performance from them.

The other side of preventive maintenance is scanning by symptoms where a specific fault with the Bendix commercial vehicle system is detected and cleared.

Either way, the Bendix diagnostic tool is a must-have software for owners of commercial vehicles with Bendix systems and components.

If you are into agriculture and own a fleet of tractors, combine harvesters, wheel loaders, skid steer loaders, and more you cannot do without our Jaltest agricultural diagnostic software. It helps you to stay a step ahead of your AGVs’ health and ensure that there are no breakdowns, especially during crucial harvesting times.

So, what is the connection between the Jaltest AGV maintenance tool and tracking the condition of the vehicle?

Modern agricultural vehicles and equipment are complex with cutting-edge technologies incorporated in them. Unlike in old times, any mechanic or certified engineer cannot easily unravel the source of a problem and have it rectified. You must take the help of diagnostic software to identify the issue and resolve it before it becomes a major one, leading to downtime.

This is why, today’s agricultural vehicles have onboard computers that monitor the state of the functioning and warn through fault codes of any malfunction before it becomes a major problem. These fault codes, typically in alpha-numeric format, pop up on the display panel of the onboard computer, generally tucked away below the dashboard on the driver’s side.

At this stage, connect the Jaltest diagnostic software to the onboard computer. It will identify the fault and what is wrong with the agricultural vehicle, and finally handhold you through the required solutions and fault clearance.

Just for your reference, it is not only agricultural vehicles that are covered by the Jaltest agricultural maintenance tool, even fault codes of stationary agricultural equipment like generators and air compressors and self-propelled equipment such as sprayers and forage harvesters are adequately covered by the Jaltest diagnostic tool.

Before proceeding with the various aspects of the Jaltest software for agricultural vehicles, it is necessary to have a clear understanding of fault codes, the key to running the Jaltest diagnostic tool.

Fault codes, usually in alpha-numeric format pop up on the display screen of the onboard computer whenever a malfunction occurs in any system or component of the AGV. These codes are different for makes and models of agricultural vehicles even though the nature of the fault might be the same. Hence, when analyzing a fault code with the Jaltest agriculture code reader, it is necessary first to enter the type and make of vehicle before going on to fault clearing processes.

Fault codes, also known as Diagnostic Trouble Codes (DTCs) are a measure of the state of the systems and components of the agricultural vehicle. Temporary fault codes are issues that are minor in nature and usually go away after a few driving cycles. When that does not happen, it is permanent fault codes that require the intervention of our Jaltest AGV diagnostic scanner to clear.

Based on these fault codes, let us now elaborate on how the Jaltest agricultural diagnostic tool works. 

Functioning Of The Jaltest Agricultural Diagnostic Scanner 

The Jaltest AGV kit is a highly optimized software that not only accurately diagnoses fault codes but also offers the right solutions to get your AGVs back on the job again. All the necessary features are built into the software that makes diagnosis and resolutions a breeze. You do not have to refer to bulky manuals or call certified engineers at the drop of a hat to get dealer-level services, the Jaltest agriculture scan tool clears fault codes effortlessly for you.

Once you access the diagnostic menu of the Jaltest software, there will be several options before you. Among the system and component analysis that will be displayed on your software laptop are recommended resolutions on various aspects. These include the central computer, climate HVAC, Electric Control Module, engine, hydraulic systems, instrument cluster, power take-off, steering, and others.

What makes the Jaltest agricultural equipment diagnostic tool a cut above the others is the deep coverage offered by it. You get detailed wiring diagrams of systems that help you to locate the precise position of the fault. You get technical data that enables you to understand the nature of a fault and the resolution required. Further, during fault analysis and diagnosis, information can be had in real-time so that you know the current nature and status of the problem.

All these together assist users in maximizing fault code reading and getting accurate solutions since they are backed by technical data and information, main system scans, special functions (shortcuts), or all system scans. For example, you can configure the right tire size needed, lighting, precisely calibrate transmissions and rear hitches, and so much more.

It is necessary here to further explain the distinction between full system scans and scanning by symptoms in our Jaltest agricultural vehicle or equipment diagnostic tool.

Full system scans are a form of preventive maintenance where all systems and components are scanned periodically. Any temporary fault code therefore can be quickly identified before it becomes a major issue that might lead to downtime and stoppage of work. Among the work done as a part of full system scans is keeping a close tab on engines, hydraulic systems, instrument clusters, electronic control modules (ECMs), central computers, powertrains, and other critical components.

Regular full-system scans help to keep your equipment on the job without a forced break and make sure that your agricultural vehicle is always in peak performance mode.

The other is scanning by symptoms where any fault code that pops up is cleared through specific action related to that symptom only. It might be related to engines, hydraulics, transmissions, HVAC, or even if there is a necessity to change or repair a component. Among the areas where you can scan by symptoms are performing force regens, code injectors, setting up flows and pressures on excavators, calibrating transmissions, and many others.

Whatever might be the fault code, our Jaltest agriculture scan tool has your back.

Jaltest Agricultural Diagnostic Software And Forced Regens

Most heavy-duty agricultural vehicles and equipment are powered by diesel engines. To cut emissions, such engines have what is known as a Diesel Particulate Filter (DPF) whose purpose is to trap small particles from emissions to ensure a clean environment. Over time though, the dpf gets clogged with particles and soot which if not cleared might lead to engine seizure or the vehicle going into limp mode.

This typically happens when it goes beyond the capabilities of passive regens to clear the soot accumulation. This state of the engine will be shown as a fault code which must then be cleared through the recommendations of the Jaltest AGV diagnostic software. The options for fault resolution range from High to Very High depending on the extent of the clogged filter.

The typical forced regens solution is to run the engine on high rev for about 40 minutes. The rise in temperature of the emission gasses burns away the soot in the DPF. However, it is advisable to clean the DPF manually if it is more than 75% clogged.

Summing Up

The Jaltest agricultural diagnostics software is a highly optimized tool that ensures your AGVs and agricultural equipment are operating optimally. The highly advanced features, detailed wiring diagrams, and technical data provided in real time make this software a leader in its class.

Moreover, you do not have to go through elaborate configuration processes after downloading the software on your laptop. All that you have to do is to connect it to the onboard computer and you are ready for fault code analysis and clearance.

Finally, we provide three updates every year to our Jaltest agricultural diagnostic software. This is to keep in sync with any developments and technological innovations implemented in AGVs over time.

Let us start with the definition of a CV or commercial vehicle. It is a type of motor vehicle that is solely used for transporting goods or passengers for a charge. In the USA, any vehicle that is registered in the name of a company is deemed a commercial vehicle regardless of whether it is a bus, car, or a fleet of heavy, medium, or light trucks. Any vehicle that carries more than 15 passengers is a commercial vehicle.

Let us now explore the connection between commercial vehicles and the Jaltest CV diagnostic tool. 

All modern vehicles compulsorily have an onboard computer that tracks and monitors the health and performance of all systems and components. Whenever a malfunction occurs, a fault code, usually in alpha-numeric format shows up on the computer for diagnosis and rectification. This is where the role of the Jaltest commercial vehicle plays a critical part. 

Let us explore this aspect in more detail and how the Jaltest CV functions. 

The Functions Of The Jaltest Commercial Vehicle Scan Tool

The onboard computer informs about the status of the commercial vehicle by registering a fault code on the display screen, typically tucked away below the dashboard on the driver’s side. To interpret this fault code, you must connect our Jaltest CV diagnostic tool and check the malfunction. The software will then guide you on how to resolve the issue so that your vehicle is back on the road at the earliest possible time.

The fault codes cover all systems and components of the vehicle ranging from the body chassis to brakes, transmissions, hydraulics, HVAC, and more. Problem resolution can be anything from fixing a loose wire to more complex ones like parameter settings, calibrations, or forced regens. Whatever might be the issue, you can bank on our Jaltest commercial vehicle maintenance tool to provide cutting-edge solutions so that your vehicle is always at peak operational efficiency without any downtime.

Preemptive and Problem Solving With Jaltest Commercial Vehicle Tool

Before going into preventive maintenance and problem-solving functions possible with the Jaltest commercial vehicle diagnostic scanner, a quick word on fault codes is necessary. 

Fault codes, also called Diagnostic Trouble Codes (DTCs) inform users of any malfunction of the vehicle. Each fault code is specific to a problem with a system or component and varies between brands and models. Hence, an engine fault code for Paccar engines of a specific issue will be different for the same problem for Cummins engines. Our Jaltest CV software covers them all and provides advanced resolutions.

The Jaltest software works in two ways – preventive functions and fault resolutions.

In the first instance, the software has a provision for full system scans that you can run periodically. This activity identifies even minor problems with quick corrective action initiated by the Jaltest tool before they become major issues that might result in downtime. Fault codes do not go unchecked for long as this full system scan is done at fixed intervals.

Any minor fault generally goes away within a few driving cycles but if they do not, fault rectification work is immediately started. Preventive maintenance and full system scans therefore make sure that your fleet of commercial vehicles is always on the job.

In the second instance, solutions are taken up when a major fault crops up and is shown on the display screen of the onboard computer. In the diagnostic software, this is shown as scans by symptoms. For example, if a fault code indicates an issue with the transmission, you can enter the make and model of the vehicle in the tool and then go to the transmission fault resolution section. Similar is the case with any other system or components like engines or brakes.   

In a nutshell then, our Jaltest diagnostic software for commercial vehicles not only forewarns you of any impending faults when you carry out full system scans but also offers advanced rectification solutions. 

Deep Coverage By The Jaltest CV Diagnostic Tool

Our Jaltest commercial vehicle maintenance tool provides deep coverage of vehicles. The specialized tool performs special functions across your fleet such as forced regens, coding injectors, calibrating VGTs, body computers and so much more.

This includes setting parameters for a host of critical activities such as speed limits and idle speeds, code injectors, and bleed braking systems. Our maintenance tool also provides system scans such as after-treatment and other resolutions for antitheft, brakes, electronic control modules, engines, hybrid systems, safety, and transmissions.

Force Regens and The Jaltest CV Diagnostic Tool

Engines are at the core of the running of any commercial vehicle and any trouble code related to it should be promptly addressed. It is advisable not to run the vehicle and to move it to an area where the fault can be checked and rectified.

Most commercial vehicles especially trucks, semi-trucks, buses, vans, and other passenger-carrying vehicles are powered by diesel engines. Among the most common issues that arise, especially in short-haul vehicles with stop-go-stop operations such as local buses and vans is soot buildup in the Diesel Particulate Filter (DPF). When this happens, the filter must immediately be cleaned to prevent the engine from seizing up and the vehicle going into limp mode.  

This condition to the DPF typically occurs when passive regens are not capable of clearing the filter and forced regens have to be applied. This process necessitates running the vehicle at high engine rev so that the increase in temperature of the exhaust gasses can burn away the soot buildup. 

When a fault code related to this trouble is displayed, connect the Jaltest commercial vehicle maintenance software to the onboard computer and you will be guided through the forced regens procedure and the specific rev the engine has to be run and the time. You can either drive the vehicle at high rev or keep it stationary and run the engine only. 

However, if the DPF clogging is more than 75%, it is recommended that you should have it cleaned manually. 

Summing Up

The Jaltest CV diagnostic tool is a must-have diagnostic software for owners of commercial vehicles. Any issue can be promptly resolved through guidance from our Jaltest commercial vehicle diagnostic scanner. All systems and components, regardless of the make or model are covered by our maintenance tool, giving optimized results to keep your vehicles on the road without downtime.

Bank on our Jaltest CV diagnostic tool as it is ahead of others in this niche. Our user-friendly tool is easy to configure and unlike others, does not require any elaborate setting up procedures.

It is said that the wealth of a nation is often measured by construction activities and infrastructure development. This is the backbone that a country depends on for overall growth and progress. It is therefore not surprising that heavy-duty trucks and construction equipment in various categories are often the preferred source for capital investment. 

However, it is not sufficient to have these vehicles and equipment only, it is more important that they are on the job without a break to avoid loss and poor returns on investment. Hence, for owners of heavy-duty construction trucks and heavy equipment, it is essential that they have a heavy equipment diagnostic tool for the maintenance and upkeep of their fleet. There is no better maintenance software than the Jaltest diagnostic tool to keep your equipment on the job.   

Fault Codes And The Function Of The Off-Highway Diagnostic Tool 

Before going into the various aspects of the Jaltest heavy equipment diagnostic tool, it is necessary to understand the concept of fault codes. This is because clearing the fault codes is the primary work of any heavy-duty diagnostic computer. 

It is now mandated by law that all modern vehicles including off-highway, construction, and materials handling equipment have a central onboard computer. Its function is to track the health of the vehicle and warn users of any malfunction in the systems and components through fault codes, also known as Diagnostic Trouble Codes (DTCs). There are hundreds of fault codes that are specific to the make, model, and particular problem in the equipment.

When a fault code pops up as a warning light on the display panel, generally tucked away below the dashboard on the driver’s side, an optimized diagnostic scanner must be used for fault resolution. The issue might be related to the engine, hydraulics, transmission, or any other system or component. 

In the case of vehicles, use the Jaltest diagnostic computer for heavy-duty trucks to bring the vehicle back on the road as soon as possible by clearing the fault codes, which will be either a temporary or a permanent one. 

In the case of a temporary fault code detected during a full system scan by the Jaltest heavy-duty diagnostic computer, minor adjustments are usually required and the fault code is cleared within a few driving cycles. However, if the fault persists, our Jaltest heavy equipment diagnostic tool will guide you through specific rectification activities that are no less than dealer-level servicing.

Forced Regens and Jaltest Heavy Equipment Diagnostic Tool

Most heavy-duty trucks, off-highway vehicles, and construction equipment are powered by diesel engines that have a diesel particulate filter (DPF) that cuts down on particles in the emissions. This makes for a cleaner environment. 

However, if not attended to and cleaned regularly, soot and other particles accumulate in the DPF, lowering engine performance, increasing fuel consumption, and in worst-case scenarios, pushing the vehicle or equipment to limp mode. 

In such cases, a fault code will show on the display of the onboard computer and when connected to the Jaltest heavy equipment diagnostic tool, you will be guided on the best way to clear the soot accumulation in the DPF. This is done through forced regeneration or forced regens, an activity that becomes necessary when passive regens are unable to clear the built-up soot. 

The process involves running the vehicle or construction equipment at high rev for about 40 minutes. The rise in temperature of the exhaust gasses burns away the soot, thereby cleaning the DPF. Based on the extent of soot in the DPF, our software will guide you on the engine rev and the time required for forced regens.
