| 1. | Turn the ignition switch ON (II). |
| 2. | Observe the A/T gear position indicator, and shift each position separately. Do any indicators stay on when the shift lever is not in that position? YES - Go to 3. NO - Go to 7. |
| 3. | Disconnect the transmission range switch connector. Do all gear position indicators go out? YES - Replace the transmission range switch.n NO - Go to 4. |
| 4. | Turn the ignition switch OFF. |
| 5. | Test the transmission range switch. Is the switch OK? YES - Go to 6. NO - Replace the transmission range switch.n |
| 6. | Connect the transmission range switch connector. |
| 7. | Turn the ignition switch ON (II). |
| 8. | Shift to all positions other than R. |
| 9. | Measure the voltage between PCM connector terminals C10 and A23 or A24.

| 12. | Check for continuity between PCM connector terminal C10 and body ground.
 Wire side of female terminalsPCM CONNECTOR C (22P)ATP R (WHT)Is there continuity? YES - Repair short in the wire between PCM connector terminal C10 and the transmission range switch or A/T gear position indicator.n NO - Go to 13. |
| 13. | Disconnect PCM connector A (31P). |
| 14. | Check for continuity between PCM connector terminals A23 and body ground, and between A24 and body ground.
 Wire side of female terminalsPCM CONNECTOR A (31P)LG1 (BRN/YEL)LG2 (BRN/YEL)Is there continuity? YES - Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.n NO - Repair open in the wire between PCM connector terminals A23 and A24, and ground (G101), or repair poor ground (G101).n |
| 15. | Shift to all positions other than P and N. |

 Wire side of female terminalsPCM CONNECTORSLG1 (BRN/YEL)LG2 (BRN/YEL)ATP NP (LT GRN)A (31P)C (22P) Is there about 5 V? YES - Go to 20. NO - Go to 17. |
| 17. | Turn the ignition switch OFF. |
| 18. | Disconnect PCM connector C (22P). |
| 19. | Check for continuity between PCM connector terminal C12 and body ground.
 Wire side of female terminalsPCM CONNECTOR C (22P)ATP NP (LT GRN)Is there continuity? YES - Repair short in the wire between PCM connector terminal C12 and the transmission range switch.n NO - Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.n |
| 20. | Shift to all positions other than D. |
| 21. | Measure the voltage between PCM connector terminals C20 and A23 or A24.
 Wire side of female terminalsPCM CONNECTORSLG1 (BRN/YEL)LG2 (BRN/YEL)ATP D (PNK)A (31P)C (22P) Is there about 5 V? YES - Go to 25. NO - Go to 22. |
| 22. | Turn the ignition switch OFF. |
| 23. | Disconnect PCM connector C (22P). |
| 24. | Check for continuity between PCM connector terminal C20 and body ground.
 Wire side of female terminalsPCM CONNECTOR C (22P)ATP D (PNK)Is there continuity? YES - Repair short in the wire between PCM connector terminal C20 and the transmission range switch.n NO - Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.n |
| 25. | Shift to all positions other than S. |
| 26. | Measure the voltage between PCM connector terminals C9 and A23 or A24.
 Wire side of female terminalsPCM CONNECTORSLG1 (BRN/YEL)LG2 (BRN/YEL)ATP S (BLU/WHT)A (31P)C (22P) Is there about 10 V? YES - Go to 30. NO - Go to 27. |
| 27. | Turn the ignition switch OFF. |
| 28. | Disconnect PCM connector C (22P). |
| 29. | Check for continuity between PCM connector terminal C9 and body ground.
 Wire side of female terminalsPCM CONNECTOR C (22P)ATP S (BLU/WHT)Is there continuity? YES - Repair short in the wire between PCM connector terminal C9 and the transmission range switch or A/T gear position indicator.n NO - Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.n |
| 30. | Shift to all positions other than L. |
| 31. | Measure the voltage between PCM connector terminals C11 and A23 or A24.
 Wire side of female terminalsPCM CONNECTORSLG1 (BRN/YEL)LG2 (BRN/YEL)ATP L (BLU)A (31P)C (22P) Is there about 10 V?
