Frequently asked questions about C003C
What does C003C mean?
Rear Tone Wheel. The control module detected a fault associated with the Rear Tone Wheel circuit or function; the stored code identifies the affected component rather than a single failure mode.
Is C003C generic or manufacturer-specific?
C003C is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove C003C 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 C003C is removable in your case.
