Shift Indicator Lamp Troubleshooting

NOTE: Check for Pending or Confirmed DTCs with the HDS before doing this procedure. If any DTCs are stored, troubleshoot them first, then do this procedure.
  1. Connect the HDS to the DLC (see GENERAL TROUBLESHOOTING INFORMATION ).
  2. Start the engine.
  3. Test-drive several minutes.
  4. Check the C SHAFT SPD in the DATA LIST with the HDS.

    Is any vehicle speed indicated? 

    YES  -Go to step  5.

    NO  -Go to the troubleshooting for P0720 (see DTC P0720: OUTPUT SHAFT (COUNTERSHAFT) SPEED SENSOR CIRCUIT MALFUNCTION (M/T MODEL)  ).

  5. Do the gauge self-diagnostic function (see SELF-DIAGNOSTIC FUNCTION ).

    Is the result OK? 

    YES  -Go to step  6.

    NO  -Substitute a known-good gauge control module, and recheck. If the symptom/indication goes away with a known-good gauge control module, replace the original gauge control module (see GAUGE CONTROL MODULE REPLACEMENT ).

  6. Do the APP sensor signal inspection (see APP SENSOR SIGNAL INSPECTION ).

    Is the result OK? 

    YES  -Go to step  7.

    NO  -Depending on the result, repair or replace the appropriate part.

  7. Do the brake pedal position switch signal circuit troubleshooting (see BRAKE PEDAL POSITION SWITCH SIGNAL CIRCUIT TROUBLESHOOTING ).

    Is the result OK? 

    YES  -Go to step  8.

    NO  -Depending on the result, repair or replace the appropriate part.

  8. Turn the ignition switch to LOCK (0).
  9. Check the position of clutch pedal position switch C (see CLUTCH PEDAL AND CLUTCH PEDAL POSITION SWITCH ADJUSTMENT ).

    Is the position correct? 

    YES  -Go to step  10.

    NO  -Do the clutch pedal and clutch pedal position switch C adjustment (see CLUTCH PEDAL AND CLUTCH PEDAL POSITION SWITCH ADJUSTMENT ).

  10. Turn the ignition switch to ON (II).
  11. Check the CLUTCH PEDAL POSITION SWITCH A (C) in the DATA LIST with the HDS.

    Is OPEN indicated? 

    YES  -Go to step  12.

    NO  -Go to step  28.

  12. Press the clutch pedal.
  13. Check the CLUTCH PEDAL POSITION SWITCH A (C) in the DATA LIST with the HDS.

    Is CLOSE indicated? 

    YES  -Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the gauge control module, clutch pedal position switch C, and the ECM.

    NO  -Go to step  14.

  14. Turn the ignition switch to LOCK (0).
  15. Disconnect the clutch pedal position switch C 2P connector.
  16. Connect clutch pedal position switch C 2P connector terminals No. 1 and No. 2 with a jumper wire.

  17. Turn the ignition switch to ON (II).
  18. Check CLUTCH PEDAL POSITION SWITCH A (C) in the DATA LIST with the HDS.

    Is OPEN indicated? 

    YES  -Go to step  19.

    NO  -Replace clutch pedal position switch C (see CLUTCH PEDAL POSITION SWITCH REPLACEMENT ).

  19. Turn the ignition switch to LOCK (0).
  20. Remove the jumper wire from the clutch pedal position switch C 2P connector.
  21. Connect clutch pedal position switch C 2P connector terminal No. 1 to body ground with a jumper wire.

  22. Turn the ignition switch to ON (II).
  23. Check CLUTCH PEDAL POSITION SWITCH A (C) in the DATA LIST with the HDS.

    Is CLOSE indicated? 

    YES  -Go to step  24.

    NO  -Repair an open in the wire between clutch pedal position switch C and body ground (G403 (see LEFT ENGINE COMPARTMENT WIRE HARNESS (BF) )).

  24. Turn the ignition switch to LOCK (0).
  25. Jump the SCS line with the HDS.
  26. Disconnect ECM connector B (44P).
  27. Check for continuity between ECM connector terminal B39 and body ground.

    Is there continuity? 

    YES  -Update the ECM if it does not have the latest software (see ECM/PCM UPDATE  ), or substitute a known-good ECM (see SUBSTITUTING THE ECM/PCM ), then recheck. If the symptom/indication goes away with a known-good ECM, replace the original ECM (see ECM/PCM REPLACEMENT  ).

    NO  -Repair an open in the wire between the ECM (B39) and the clutch pedal position switch C.

  28. Turn the ignition switch to LOCK (0).
  29. Disconnect the clutch pedal position switch C 2P connector.
  30. Turn the ignition switch to ON (II).
  31. Check CLUTCH PEDAL POSITION SWITCH A (C) in the DATA LIST with the HDS.

    Is OPEN indicated? 

    YES  -Replace clutch pedal position switch C (see CLUTCH PEDAL POSITION SWITCH REPLACEMENT ).

    NO  -Go to step  32.

  32. Turn the ignition switch to LOCK (0).
  33. Jump the SCS line with the HDS.
  34. Disconnect ECM connector B (44P).
  35. Check for continuity between ECM connector terminal B39 and body ground.

    Is there continuity? 

    YES  -Repair a short in the wire between the ECM (B39) and clutch pedal position switch C.

    NO  -Update the ECM if it does not have the latest software (see ECM/PCM UPDATE  ), or substitute a known-good ECM (see SUBSTITUTING THE ECM/PCM ), then recheck. If the symptom/indication goes away with a known-good ECM,, replace the original ECM (see ECM/PCM REPLACEMENT  ).
