    • Carry out a visual inspection.
    • Carry out the PCM self-test.
    • Record the freeze frame data.
    • Clear the PCM DTCs.
    • Carry out the PCM self-test.

    Are DTCs P0606, P0607 or P2610 present? 

    Yes No
    GO to  Z2. The concern is not present at this time. CHECK for a loose connection, and damaged or corroded terminals. WIGGLE the harness attempting to recreate the concern. REPAIR as necessary. REFER to SYMPTOM CHARTS GO to PINPOINT TEST QT if a driveability concern exists.

  3. Z3 CHECK THE KAPWR CIRCUIT FOR VOLTAGE 
    • Ignition OFF.
    • PCM-B connector disconnected.
    • Ignition ON, engine OFF.
    • Measure the voltage between:
      (+) PCM-B Connector, Harness Side (-)
      KAPWR - Pin 62 Ground

    Is the voltage greater than 10 V? 

    Yes No
    CHECK for loose connections and damaged terminals. WIGGLE the harness attempting to recreate the concern. REPAIR as necessary. REPAIR the open circuit. Clear the PCM DTCs.

    • Carry out the PCM self-test.
    • Verify the concern is still present.

    Is the concern still present? 

    Yes No
    INSTALL a new PCM. REFER to FLASH ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY (EEPROM) . The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
