Diagnostic Trouble Code (DTC) Information
Condition
The diagnostic trouble code only applies to vehicles equipped with DSTC.
The AYC sensor for DSTC consists of a yaw speed sensor, lateral accelerometer, accelerometer (AWD only) and inclination sensor (RSC only). Via its own internal CAN network, the sensors transmit information to the brake control module (BCM) on the size of the yaw angle, vehicle acceleration both laterally and straight ahead as well as lateral inclination. Each sensor has an offset value, correction value, for individual sensor deviations.
If the brake control module (BCM) registers an incorrect offset value from one of the sensors, diagnostic trouble code BCM-C006128, BCM-C006228, BCM-C006328 or BCM-C111486 is generated depending on the sensor.
- BCM-C006128: Lateral accelerometer
- BCM-C006228: Accelerometer
- BCM-C006328: Yaw speed sensor
- BCM-C111486: Inclination sensor
The diagnostic trouble code can be diagnosed when the ignition is on.
Substitute Value
- TC is blocked.
- SC is blocked.
- AYC is blocked.
- RSC is blocked (only vehicles with RSC).

Possible Source
- AYC sensor improperly mounted.
- Loose AYC sensor.
- Bent AYC sensor bracket.
- Internal malfunction in AYC sensor.
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]
- General warning light on.
- Anti-spin is not operational.
- The stability function is not operational.
- The anti-skid function is not operational.
