ABS System Diagnostics in Morris County NJ — Get Your Anti Lock Braking System Working Right

The most obvious sign is the ABS warning light staying on. This means your system has detected a fault and has disabled itself. Your trailer brakes still work, but you lose the anti lock protection that prevents wheel lockup. If your ABS is not engaging during hard braking and your wheels are skidding instead of pulsing, the system is not doing its job. Sensor codes are common triggers, usually caused by damaged wheel speed sensors or corroded wiring. After any accident or impact to the axle area, an ABS inspection should be part of the repair to make sure sensors and tone rings are still functioning properly. Not sure if your trailer has ABS? If not, you may just need standard brake repair for non-ABS trailers instead. A working ABS system is required on equipped trailers. Get a DOT inspection to confirm ABS compliance before your next roadside check.

We connect our diagnostic equipment and read the ABS fault codes stored in the module. These codes tell us exactly which component triggered the fault. We inspect the wheel speed sensors at each ABS equipped axle position, checking for physical damage, proper air gap, and correct resistance readings. We inspect the tone rings on the hubs for missing teeth or damage. We test the ABS module itself to confirm it is receiving and processing sensor data correctly. If wiring is the issue, we trace the circuit and repair the damaged section. Once everything is repaired, we clear the codes and road test to confirm the system is working.

ABS diagnostic costs vary based on what component has failed. A sensor replacement is a straightforward and affordable repair. If the ABS module needs replacement, that is a more involved job. The number of axles equipped with ABS affects the scope of the inspection. Wiring repairs depend on the extent of the corrosion or damage. We always provide an upfront quote after reading the fault codes so you know exactly what the repair will cost. No hidden fees. Fleet customers with 3 or more trailers receive a 10% discount on every service call.
