  • Internal control module hardware fault
  • Control module supply voltage or ground fault
  • Software/coding fault after programming
  • In rare cases, interference from wiring faults

Recommended checks

  • Check control module power supplies and grounds first
  • Check battery condition and charging voltage
  • Verify software version and check OEM bulletins
  • Clear the code and retest under the original conditions
  • Only after supply-side checks, consider module assessment

Frequently asked questions about C05D6

What does C05D6 mean?

Power Steering Control Module Processor Performance. The control module judged the Power Steering Control Module Processor behaviour implausible for the current operating conditions.

Is C05D6 generic or manufacturer-specific?

C05D6 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove C05D6 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 C05D6 is removable in your case.
