C0186 Code: Meaning, Causes, and Symptoms | OBD2 Codes
C0186 – Lateral Accelerometer Circuit
C0186 Possible Symptoms
Anti-Lock Brake System (ABS) Warning Light ON,Engine Light ON (or Service Engine Soon Warning Light)
C0186 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
C0186 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.
