Frequently asked questions about C0631
What does C0631 mean?
Front Axle Disconnect Actuator. The control module detected a fault associated with the Front Axle Disconnect Actuator circuit or function; the stored code identifies the affected component rather than a single failure mode.
Is C0631 generic or manufacturer-specific?
C0631 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove C0631 at file level?
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. Ask for a quote and our engineers will check your file and tell you, free of charge, whether C0631 is removable in your case.
