  1. Normal Operation and Fault Conditions 

    The ABS module incorporates a function for testing the vehicle on a dynamometer to prevent wheel speed sensor Diagnostic Trouble Codes (DTCs) from setting during testing. The PCM sends a message to the ABS module when the vehicle is setup for testing. When the ABS module receives this message it knows to ignore discrepancies between the front and rear wheel speed sensors.

    The ABS module exits the test mode automatically when the PCM sends the exit message, the ignition is set to OFF, either of the non-driven wheels exceeds 20 km/h (12 mph) or a wheel speed sensor DTC is detected on any wheel speed sensor.

    REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
