P0705
DTC P0705: Short in Transmission Range Switch Circuit (Multiple Shift-position Input)NOTE:
^ Record all freeze data and review 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. Clear the DTC with the HDS.
2. Start the engine.
3. Move the shift lever through all positions, stopping for at least 1 second in each position. Monitor the OBD status for P0705 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate FAILED?
YES - Go to step 4.
NO - Intermittent failure, the system is OK at this time. Check for an intermittent short in the wire between the transmission range switch and the PCM. If the tester indicates NOT COMPLETED, return to step 2 and recheck. E
4. Inspect the transmission range switch.
Is the switch OK?
YES - Reconnect the switch connector, then go to step 5.
NO - Replace the transmission range switch, then go to step 44.
5. Turn the ignition switch ON (II).
6. Measure the voltage between PCM connector terminals D13 and A3 or B15, in all positions other than P.
Is there battery voltage?
YES - Go to step 14.
NO - Go to step 7.
7. Turn the ignition switch OFF.
8. Jump the SCS line with the HDS.
9. Disconnect PCM connector D (17P).
10. Disconnect the transmission range switch connector.
11. Check for continuity between PCM connector terminal D13 and body ground.
Is there continuity?
YES - Repair a short in the wire between PCM connector terminal D13 and the transmission range switch, then go to step 44.
NO - Go to step 12.
12. Disconnect PCM connectors A (31P) and B (24P).
13. Check for continuity between transmission range switch connector terminals A3 and body ground, and between B15 and body ground.
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.
NO - Repair an open in the wire between PCM connector terminals A3, B15, and ground (G101, G102), or repair a poor ground (G101, B102), then go to step 44.
14. Measure the voltage between PCM connector terminals D16 and A3 or B15, in all positions other than R.
Is there battery voltage?
YES - Go to step 20.
NO - Go to step 15.
15. Turn the ignition switch OFF.
16. Jump the SCS line with the HDS.
17. Disconnect PCM connector D (17P).
18. Disconnect the transmission range switch connector.
19. Check for continuity between PCM connector terminal D16 and body ground.
Is there continuity?
YES - Repair a short in the wire between PCM connector terminal D16 and the transmission range switch, then go to step 44.
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.
20. Measure the voltage between PCM connector terminals B23 and A3 or B15, in all, positions other than N.
Is there battery voltage?
YES - Go to step 26.
NO - Go to step 21.
21. Turn the ignition switch OFF.
22. Jump the SCS line with the HDS.
23. Disconnect PCM connector B (24P).
24. Disconnect the transmission range switch connector.
25. Check for continuity between PCM connector terminal B23 and body ground.
Is there continuity?
YES - Repair a short in the wire between PCM connector terminal B23 and the transmission range switch, then go to step 44.
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.
26. Measure the voltage between PCM connector terminals C10 and A3 or B15, in all positions other than D.
Is there battery voltage?
YES - Go to step 32.
NO - Go to step 27.
27. Turn the ignition switch OFF.
28. Jump the SCS line with the HDS.
29. Disconnect PCM connector C (22P).
30. Disconnect the transmission range switch connector.
31. Check for continuity between PCM connector terminal C10 and body ground.
Is there continuity?
YES - Repair a short in the wire between PCM connector terminal C10 and the transmission range switch, then go to step 44.
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.
32. Measure the voltage between PCM connector terminals C18 and A3 or B15, in all positions other than D3.
Is there battery voltage?
YES - Go to step 38.
NO - Go to step 33.
33. Turn the ignition switch OFF.
34. Jump the SCS line with the HDS.
35. Disconnect PCM connector C (22P).
36. Disconnect the transmission range switch connector.
37. Check for continuity between PCM connector terminal C18 and body ground.
Is there continuity?
YES - Repair a short in the wire between PCM connector terminal C18 and the transmission range switch, then go to step 44.
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.
38. Measure the voltage between PCM connector terminals C19 and A3 or B5, in all positions other than D and D3.
Is there battery voltage?
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.
