DTC P0705: Short in Transmission Range Switch Circuit (Multiple Shift-position Input)
2005 Model

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. Shift the shift lever out of the P position, then move to each position slowly.
3. Check that DTC P0705 recurs.
Is DTC P0705 indicated?
YES- Go to step 4.
NO- Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the transmission range switch and TCM.
4. Test the transmission range switch.
Is the switch OK?
YES- Go to step 5.
NO- Replace the transmission range switch, then go to step 14.
5. Turn the ignition switch ON (II).
6. Shift to all positions other than R.





7. Measure the voltage between TCM connector terminals A11 and A4 or A17.
Is there about 10 V?
YES- Go to step 8.
NO- Check for short in the wire between TCM connector terminal A11 and the transmission range switch or A/T gear position indicator, and check for an open in the wires between TCM connector terminals A4, A17, and ground (G101). If the wires are OK, check for loose terminal fit in the TCM connectors. If necessary, substitute a known-good TCM, then recheck. If the symptom/indication goes away with a known-good TCM, replace the original TCM.
8. Shift to any position other than P and N.





9. Measure the voltage between TCM connector terminals A10 and A4 or A17.
Is there about 5 V?
YES- Go to step 10.
NO- Check for short in the wire between TCM connector terminal A10 and the A/T gear position indicator, and check for short in the P and N position wires between the gauge assembly and the transmission range switch. If the wires are OK, check for loose terminal fit in the TCM connectors. If necessary, substitute a known-good TCM, then recheck. If the symptom/indication goes away with a known-good TCM, replace the original TCM.
10. Shift to any position other than D.





11. Measure the voltage between TCM connector terminals A9 and A4 or A17.
Is there about 5 V?
YES- Go to step 12.
NO- Check for short in the wire between TCM connector terminal A9 and the transmission range switch. If the wire is OK, check for loose terminal fit in the TCM connectors. If necessary, substitute a known-good TCM, then recheck. If the symptom/indication goes away with a known-good TCM, replace the original TCM.
12. Shift to any position other than L.





13. Measure the voltage between TCM connector terminals A7 and A4 or A17.
Is there about 10 V?
YES- Check for loose terminal fit in the TCM connectors. If necessary, substitute a known-good TCM and recheck.
NO- Check for short in the wire between TCM connector terminal A7 and the transmission range switch or A/T gear position indicator. If the wire is OK, check for loose terminal fit in the TCM connectors. If necessary, substitute a known-good TCM, then recheck. If the symptom/indication goes away with a known-good TCM, replace the original TCM.
14. Clear the DTC with the HDS.
15. Shift the shift lever out of the P position, then move to each position slowly.
16. Check that DTC P0705 recurs.
Is DTC P0705 indicated?
YES- Return to step 4 and recheck.
NO- The problem has been corrected.
