P0705
DTC P0705: 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 to each position, and check the OBD STATUS in DTCs MENU for a pass/fail test of code P0705.
Did the result indicate a fail?
YES-Go to step 4.
NO-Intermittent failure, the system is OK at this time. Check for an intermittent short in the wires between the transmission range switch and PCM. If the tester indicates NOT COMPLETE, return to step 1 and recheck.
4. Inspect the transmission range switch.
Is the switch OK?
YES-Go to step 5.
NO-Replace the transmission range switch, then go to step 38.
5. Turn the ignition switch ON (II).
6. Measure the voltage between PCM connector terminals C17 and B15 or E3 in all positions other than P.
Is there battery voltage?
YES-Go to step 13.
NO-Go to step 7.
7. Turn the ignition switch OFF.
8. Jump the SCS line with the HDS.
9. Disconnect PCM connector C (22P).
10. Check for continuity between PCM connector terminal C17 and body ground.
Is there continuity?
YES-Repair short in the wire between PCM connector terminal C17 and the transmission range switch, then go to step 38.
NO-Go to step 11.
11. Disconnect PCM connectors B (24P) and E (31P).
12. Check for continuity between PCM connector terminals B15 and body ground, and between E3 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 open in the wire between PCM connector terminals B15, E3, and ground (G101, G102), or repair poor ground (G101, G102), then go to step 38.
13. Measure the voltage between PCM connector terminals C11 and B15 or E3 in all positions other than R.
Is there battery voltage?
YES-Go to step 18.
NO-Go to step 14.
14. Turn the ignition switch OFF.
15. Jump the SCS line with the HDS.
16. Disconnect PCM connector C (22P).
17. Check for continuity between PCM connector terminal C11 and body ground.
Is there continuity?
YES-Repair short in the wire between PCM connector terminal C11 and the transmission range switch, then go to step 38.
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.
18. Measure the voltage between PCM connector terminals B23 and B15 or E3 in all positions other than N.
Is there battery voltage?
YES-Go to step 23.
NO-Go to step 19.
19. Turn the ignition switch OFF.
20. Jump the SCS line with the HDS.
21. Disconnect PCM connector B (24P).
22. Check for continuity between PCM connector terminal B23 and body ground.
Is there continuity?
YES-Repair short in the wire between PCM connector terminal B23 and the transmission range switch, then go to step 38.
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.
23. Measure the voltage between PCM connector terminals C10 and B15 or E3 in all positions other than D.
Is there battery voltage?
YES-Go to step 28.
NO-Go to step 24.
24. Turn the ignition switch OFF.
25. Jump the SCS line with the HDS.
26. Disconnect PCM connector C (22P).
27. Check for continuity between PCM connector terminal C10 and body ground.
Is there continuity?
YES-Repair short in the wire between PCM connector terminal C10 and the transmission range switch, then go to step 38.
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.
28. Measure the voltage between PCM connector terminals C18 and B15 or E3 in all positions other than L.
Is there battery voltage?
YES-Go to step 33.
NO-Go to step 29.
29. Turn the ignition switch OFF.
30. Jump the SCS line with the HDS.
31. Disconnect PCM connector C (22P).
32. Check for continuity between PCM connector terminal C18 and body ground.
Is there continuity ?
YES-Repair short in the wire between PCM connector terminal C18 and the transmission range switch, then go to step 38.
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.
33. Measure the voltage between PCM connector terminals C19 and B15 or E3 in all positions other than L.
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.
NO-Go to step 34.
34. Turn the ignition switch OFF.
35. Jump the SCS line with the HDS.
36. Disconnect PCM connector C (22P).
37. Check for continuity between PCM connector terminal C19 and body ground.
Is there continuity?
YES-Repair short in the wire between PCM connector terminal C19 and the transmission range switch, then go to step 38.
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. Clear the DTC with the HDS.
39. Move the shift lever to each position, and check the OBD STATUS in DTCs MENU for a pass/fail test of code P0705.
Did the result indicate a pass?
YES-The problem has been corrected.
NO-Return to step 1 and recheck.
