C00A4 Driveline Control Module Rear Differential Unit B Control Circuit Driver

Driveline Control Module Rear Differential Unit B Control Circuit Driver. The control module detected a fault associated with the Driveline Control Module Rear Differential Unit B Control Circuit Driver circuit or function; the stored code identifies the affected component rather than a single failure mode.

C00A4 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot.
