DTC P0706: Open in Transmission Range Switch Circuit
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. Test the transmission range switch.
Is the switch OK?
YES- Go to step 2.
NO- Replace the transmission range switch, then go to step 13.
2. Connect the transmission range switch connector.





3. Check for continuity between TCM connector terminal A4 and body ground, and between A17 and body ground.
Is there continuity?
YES- Go to step 4.
NO- Repair open in the wires between TCM connector terminals A4, A17, and ground (G101), or repair poor ground (G101).
4. Turn the ignition switch ON (II).
5. Shift to the R position.





6. Measure the voltage between TCM connector terminals A11 and A4 or A17.
Is there voltage?
YES- Repair open in the wire between TCM connector terminal A11 and the transmission range switch.
NO- Go to step 7.
7. Shift to the P or N position.





8. Measure the voltage between TCM connector terminals A10 and A4 or A17.
Is there voltage?
YES- Repair open in the wire between TCM connector terminal A10 and the A/T gear position indicator.
NO- Go to step 9.
9. Shift to the D position.





10. Measure the voltage between TCM connector terminals A9 and A4 or A17.
Is there voltage?
YES- Repair open in the wire between TCM connector terminal A9 and the transmission range switch.
NO- Go to step 11.
11. Shift to the L position.





12. Measure the voltage between TCM connector terminals A7 and A4 or A17.
Is there voltage?
YES- Repair open in the wire between TCM connector terminal A7 and the transmission range switch.
NO- 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.
13. Clear the DTC with the HDS.
14. Test-drive the vehicle in the D position until the vehicle speed reaches 31 mph (50 km/h), and stop the wheels.
15. Check that DTC P0706 recurs.
Is DTC P0706 indicated?
YES- Return to step 1 and recheck.
NO- The problem has been corrected.
