2002-2004 Models

NOTE:
  • Record all freeze data and review General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION  ) before you troubleshoot.
  • This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
  1. Turn the ignition switch OFF.
  2. Disconnect the shift solenoid harness connector.
  3. Turn the ignition switch ON (II).
  4. Measure the voltage between shift solenoid harness connector terminal No. 6 and body ground.

    Is there about 5 V? 

    1. YES -  Go to step 5.
    2. NO -  Go to step  13.
  5. Turn the ignition switch OFF.
  6. Disconnect PCM connector A (31P).
  7. Check for continuity between shift solenoid harness connector terminal No. 7 and PCM connector terminal A10.

    Is there continuity? 

    1. YES -  Go to step 8.
    2. NO -  Repair open in the wire between PCM connector terminal A10 and the shift solenoid harness connector.
  8. Connect PCM connector A (31P).
  9. Turn the ignition switch ON (II).
  10. Measure the voltage between shift solenoid harness connector terminals No. 6 and No. 7.

    Is there about 5 V? 

    1. YES -  Check the ATF temperature sensor and shift solenoid harness in the transmission housing (see ATF TEMPERATURE SENSOR TEST/REPLACEMENT  ).
    2. NO -  Go to step 11.
  11. Turn the ignition switch OFF.
  12. Check for continuity between shift solenoid harness connector terminal No. 7 and body ground.

    Is there continuity? 

    1. YES -  Update the PCM if it does not have the latest software, or substitute a known-good PCM (see PCM UPDATING AND SUBSTITUTION FOR TESTING  ), then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.
    2. NO -  Repair open in the wires between PCM connector terminal A23 and ground (G101), between A24 and ground (G101), and repair poor ground (G101).
  13. Measure the voltage between PCM connector terminal C14 and body ground.

    Is there about 5 V? 

    1. YES -  Repair open in the wire between PCM connector terminal C14 and the shift solenoid harness connector.
    2. NO -  Check for a short in the wire between PCM connector terminal C14 and the shift solenoid harness connector. If the wire is OK, update the PCM if it does not have the latest software, or substitute a known-good PCM (see PCM UPDATING AND SUBSTITUTION FOR TESTING  ), then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.
