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.
