Frequently asked questions about C003D
What does C003D mean?
Rear Wheel Speed Sensor. The control module detected a fault associated with the Rear Wheel Speed Sensor circuit or function; the stored code identifies the affected component rather than a single failure mode.
Is C003D generic or manufacturer-specific?
C003D is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove C003D 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 C003D is removable in your case.
