Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information BCM-C006428

Condition

Note! The diagnostic trouble code (DTC) only applies to vehicles with roll control (RSC).

The Supplemental Restraint System Module (SRS) provides the Brake control module (BCM) with information about the lateral acceleration, the forward acceleration and yaw-angle speed of the vehicle. The Supplemental Restraint System Module (SRS) then sends the information to the Brake control module (BCM) via sensor CAN. Each sensor has an offset value, correction value, for the individual sensor offset.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The offset value, when compared to the saved value, is outside its permitted range.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.

Substitute value
- Traction control (TC) blocked.
- Stability control (SC) blocked.
- Active yaw control (AYC) is blocked.
- Roll control (RSC) blocked.

Hint: Brake system, abbreviations Brake System, Abbreviations

Possible source
- Trace the cause of the fault in the supplemental restraint system module (SRS).

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.
