“As a driver, if you notice an ABS light illuminated on the dash or another indication the ABS system is not performing correctly, we recommend you follow fleet procedures to have a qualified technician look at the vehicle,” Screeton says. “Considering the Bendix stability ECUs on trailers now, blink codes will only go so far in helping to diagnose ABS issues and are best supplemented with diagnostic software.” What drivers can do “Blink codes can be useful for trailer ABS diagnostics, but they are limited,” says Brian Screeton, Bendix manager of technical training. If troubleshooting indicates the basic ABS components - wheel speed sensors and modulators, for example - are not malfunctioning, then it could be chassis wiring or other complex issues that would require in-depth troubleshooting to get to the root cause, Bendix says.

The software is key to diagnosing and troubleshooting ABS faults on ABS systems since it provides specific information about what may be wrong with the system, as well as procedures on how to diagnose and repair it. Again: Not an out-of-service violation, but it is recordable, and you can be ticketed for it, so the best thing to do is address an illuminated lamp as soon as possible.”īrake manufacturers and OEMs provide diagnostic software designed specifically for the braking or vehicle systems they manufacture or include on their vehicles. If any of the lamps remain on, they’ll take that as a sign of a malfunction.

“If it is, they’ll ensure the lamps cycle on and off during the diagnostic check. “During a CVSA roadside inspection, the inspector’s going to first check to see whether ABS is required on your vehicle,” Hurley says. Bendix says trailer ABS malfunction indicator lamps are located on the exterior near the red rear side marker lamp on the driver’s side converter dollies also need to have the lamp located on the driver’s side. And they need to be clearly identified with the letters “ABS.” In-cab, they’re easily spotted on the dashboard - they are standard lights and look the same on all vehicles. Because ABS activates only under specific conditions, it can be difficult for drivers to tell if the system is in good operating condition - that’s why the CVSA focuses its inspections on the yellow or amber malfunction indicator light (MIL).
