Antilock Brake System (ABS): 1151

1151-YAW RATE/ACCELERATION SENSOR - PLAUSIBILITY ERROR





When Monitored and Set Condition
^ When Monitored: With the ignition On. The Controller Antilock Brake (CAB) monitors the status of the ESP Yaw Rate/Lateral Acceleration Sensor.
^ Set Condition: The Controller Antilock Brake (CAB) will set this DTC if the calculated ESP Yaw Rate/Lateral Acceleration Sensor is out of the specified range.

POSSIBLE CAUSES
- IMPROPERLY MOUNTED ESP YAW RATE/LATERAL ACCELERATION SENSOR
- LOOSE ESP YAW RATE/LATERAL ACCELERATION SENSOR

1. VISUALLY INSPECT COMPONENTS FOR DAMAGE AND CORRECT INSTALLATION
Visually inspect the Yaw Rate/Acceleration Sensor for damage and correct installation.
Are there any visible Yaw Rate/Acceleration Sensor concerns?
Yes >> Correct the sensor concerns as necessary Perform ABS VERIFICATION TEST. ABS Verification Test
No >> Go to 2

2. MONITOR THE CAB WITH THE DRBIII





With the DRBIII, erase DTCs. Start the engine. With an assistant to drive, use the DRBIII to monitor the CAB module DTCs while performing road test.
Is the Yaw Rate/Acceleration Sensor DTC set?
Yes >> Replace the Yaw Rate/Acceleration Sensor. Perform ABS VERIFICATION TEST. ABS Verification Test
No >> Inspect and repair the related wiring harness for a possible intermittent condition. Perform ABS VERIFICATION TEST. ABS Verification Test
