Diagnostic Trouble Code Definition
- The DTCs indicate failure of a specific sensor and/or circuit. Sensor/circuit diagnosis may indicate replacement of PCM.
- If PCM is replaced at any point during diagnostic testing and if condition is still not corrected after replacing PCM, the following may be the cause:
- An incorrect PCM may cause a malfunction, which may or may not set a DTC.
- The PCM connector may be the problem. Connector terminals may have to be removed from connector to be properly checked.
- Replacement PCM may be faulty.
- Intermittent problem. Make a careful physical inspection of affected sensor/circuit.
- A shorted solenoid, coil relay, or harness may be the cause of PCM failure. Use Short Circuit Tester (J-34636) to check for short circuits.
