Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition





Note! The diagnostic trouble code (DTC) applies only to cars with dynamic stability and traction control (DSTC).

The yaw rate sensor, lateral accelerometer, accelerometer (only AWD) and angle of lean sensor (only RSC) are integrated in the active yaw control sensor for DSTC. The sensors transmit information to the brake control module (BCM) indicating the size of the yaw angle, the lateral acceleration of the car, the forward acceleration and the lateral angle of lean via its own internal Control area network (CAN). Each sensor has an offset value, correction value, for the individual sensor offset.
Diagnostic trouble code (DTC) BCM-0080, BCM-0081, BCM-0082 or BCM-0083 is stored, depending on the sensor, if the control module registers an incorrect offset value from any of the sensors.
- BCM-0080: Lateral accelerometer
- BCM-0081: Accelerometer
- BCM-0082: Yaw rate sensor
- BCM-0083: Angle of lean sensor.
The diagnostic trouble code (DTC) can be diagnosed while the ignition is switched on.

Substitute value
- Traction control is blocked
- Stability control is blocked
- Active yaw control is blocked
- RSC system is blocked (cars equipped with RSC only).

Hint: For information about brake system abbreviations, see Brake system, abbreviations Brake System, Abbreviations.

Possible source
- Active yaw control sensor incorrectly installed
- The active yaw control sensor is loose
- The bracket for the active yaw control sensor is bent
- Internal fault in the active yaw control sensor.

Note! This diagnostic trouble code (DTC) is not due to an internal hardware fault in the Brake control module (BCM) and must not be remedied by replacing the control module.

Fault symptom[s]
- The anti-spin warning lamp is lit (up to and including 2002 model year)
- General yellow warning lamp lit (from model year 2003)
- Text window and warning symbol/Red symbol and text message
- Anti-spin does not function
- The stability control system does not function
- The traction control system does not function.
