Diagnostic Trouble Code Definition

  1. The DTCs indicate failure of a specific sensor and/or circuit. Sensor/circuit diagnosis may indicate replacement of PCM.
  2. 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.
