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 and the lateral accelerometer are integrated in the body sensor cluster stability sensor (BSC) for DSTC (dynamic stability and traction control). The sensors transmit information to the brake control module (BCM) indicating the size of the yaw angle and the lateral acceleration of the car via the control area network (CAN).
Diagnostic trouble code (DTC) BCM-0090 or BCM-0092 is stored, depending on the sensor, if the control module registers a faulty signal from any of the sensors.
- BCM-0090: Lateral accelerometer
- BCM-0092: Yaw rate sensor.
The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.

Substitute value
- Traction Control is blocked
- Stability Control is blocked
- Active yaw control is blocked.

Hint: Brake system, abbreviations Brake System, Abbreviations

Possible source
- Internal fault in the body sensor cluster stability sensor (BSC).

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 information lamp is lit
- Traction control does not function
- The stability control system does not function.
