Diagnostic trouble code information
Condition
NOTE:
This diagnostic trouble code applies only to ABS systems equipped with DSTC.
The pedal pressure sensor is located inside the brake booster and sends the ABS control unit a signal if the AYC function has to be disconnected. When the AYC is active and the driver depresses the brake pedal at the same time, the pedal pressure sensor sends a signal if the AYC function has to be disconnected. If the control unit registers a faulty signal from the pedal pressure sensor, diagnostic trouble code ABS-00B1 is set.
