Frequently asked questions about C004D
What does C004D mean?
Brake System Pressure Slow Response. The control module detected that the Brake System Pressure responded more slowly than expected.
Is C004D generic or manufacturer-specific?
C004D is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove C004D 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 C004D is removable in your case.
