Cruise Control DTCS: Pcm
PCM DIAGNOSTIC TROUBLE CODE (DTC) LIST
| DTC | Description | Action |
|---|---|---|
| P0504 | Brake Switch A/B Correlation | Go to PINPOINT TEST B . |
| P0578 | Cruise Control Multifunction Input A Circuit Stuck | The PCM compares the CAN signal from the different inputs of the cruise control switches and determines that one or more of the switches are stuck. DIAGNOSE all other Instrument Panel Cluster (IPC) and PCM DTCs first. If no other DTCs are present, CLEAR the DTC. Make sure no cruise control switches are pressed and REPEAT the self-test. If DTC P0578 sets again, INSTALL a new PCM. Refer to ELECTRONIC ENGINE CONTROLS . TEST the system for normal operation. |
| P0579 | Cruise Control Multifunction Input A Circuit Range/Performance | The PCM internally monitors and compares the CAN signal message from the IPC of the cruise control switch inputs with the PCM cruise control internal state. If the PCM detects a discrepancy between the input message and the PCM then DTC P0597 sets in the PCM. DIAGNOSE all other IPC and PCM DTCs first. If no other DTCs are present, CLEAR the DTC. REPEAT the self-test. If DTC P0597 sets again, INSTALL a new PCM. Refer to ELECTRONIC ENGINE CONTROLS . TEST the system for normal operation. |
| P0833 | Clutch Pedal Switch B Circuit | Go to PINPOINT TEST E . |
| P162D | Internal Control Module Cruise Control Performance | The PCM internally monitors the disable inputs for cruise control. If a cruise control disable is requested and the cruise control output from the PCM is still being controlled then DTC P162D sets in the PCM. DIAGNOSE all other DTCs and symptoms first. If no other DTCs or symptoms are present, INSTALL a new PCM. Refer to ELECTRONIC ENGINE CONTROLS . TEST the system for normal operation. |
