Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information BCM-0074

Condition




The brake control module (BCM) can register this diagnostic trouble code (DTC) for a number of different fault causes. The diagnostic trouble code (DTC) is stored:
- if there is a short-circuit to ground or open-circuit in the control module inlet or outlet valve circuits
- if the control module is subject to interference so that its calculations are incorrect
- if the control module registers a fault in its internal inlet and outlet valve circuits
- if there is a short-circuit to ground, short-circuit to supply voltage an open-circuit in the circuit for the inlet valve in the traction control circuit in the control module
- if the control module registers an open-circuit or short-circuit in one of its internal circuits.

Substitute value
- ABS is blocked
- Traction Control is blocked
- Stability Control is blocked
- Active yaw control is blocked
- Electronic brake force distribution is blocked.

Hint: Brake system, abbreviations Brake System, Abbreviations

Possible source
- Internal fault in the brake control module (BCM).

Fault symptom[s]
- The ABS warning lamp is lit
- General warning lamp lit
- The warning lamp for brake circuit not functioning is lit
- The ABS system does not function
- Traction control does not function
- The stability control system does not function.
