Frequently asked questions about U013C
What does U013C mean?
Lost Communication With Accelerator Pedal Module. The control module stopped receiving expected network messages from the Accelerator Pedal Module node on the vehicle communication bus.
Is U013C generic or manufacturer-specific?
U013C is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove U013C 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 U013C is removable in your case.
