The ABS light remains on after its brief self-test during startup. What does it mean?
There is a fault stored, but ABS will intervene during certain traction events
The conventional braking system will have reduced functionality
There is a fault stored, and ABS will not intervene during traction events
The conventional braking system becomes fully disabled
A customer states that the ASR/ESC lamp flashed briefly last week on a curvy road, but there are no faults stored. What is the most likely cause?
The ABS module is faulty because it didn't store faults
The ESC module is faulty because it didn't store faults
There was a traction event and the system operated normally
There are worn brake pads that require replacement.
