Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information BCM-C006464

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 signal during comparison does not correspond with the calculated value.
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
- Value outside its permitted range detected. If the DTC is in the Supplemental Restraint System Module (SRS) there may be a fault with 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.

Fault symptom[s]
- Text window and warning symbol/Yellow symbol and text message
- Warning lights and chimes/Antispin/antiskid (DSA, TRACS, STC, DSTC) indication/no indication
- Stability function/Does not work
- Anti-spin function/Does not work
- Cruise control/Does not engage
- Brake pedal/Excessive "brake pedal effort" required
- Front monitoring/Active safety/City Safety does not work
