C0187 Code: Meaning, Causes, and Symptoms | OBD2 Codes

C0187 – Lateral Accelerometer Circuit Range/Performance


C0187 Possible Symptoms


Anti-Lock Brake System (ABS) Warning Light ON,Engine Light ON (or Service Engine Soon Warning Light)


C0187 Possible Causes


Faulty Yaw Sensor/Lateral Accelerometer Sensor,Yaw Sensor/Lateral Accelerometer Sensor harness is open or shorted,Yaw Sensor/Lateral Accelerometer Sensor circuit poor electrical connection


C0187 Description


The lateral accelerometer and the yaw rate sensors are combined into one sensor external to the Electronic Brake Control Module (EBCM). The vehicle stability enhancement system (VSES) uses the lateral accelerometer input when calculating the desired yaw rate. The yaw rate/lat sensor communicates with the EBCM via discrete CAN Bus High and CAN Bus Low serial data circuits.
