DTC P1706: Open in Transmission Range Switch Circuit

NOTE: Record all freeze data and review General Troubleshooting Information before you troubleshoot.

1. Test the transmission range switch.
Is the switch OK?
YES - Go to step 2.
NO - Replace the transmission range switch.
2. Turn the ignition switch OFF.





3. Check for continuity between PCM connector terminals B20 and B22, and body ground.
Is there continuity?
YES - Go to step 4.
NO - Repair open in the wire between PCM Connector terminals B20 and B22, and ground (G101), or repair poor ground (G101).
4. Turn the ignition switch ON (II).
5. Shift to D position.





6. Measure the voltage between PCM connector terminals D9 and B20 or B22.
Is there voltage?
YES - Repair open in the wire between PCM connector terminal D9 and the transmission range switch.
NO - Go to step 7.
7. Shift to R position.





8. Measure the voltage between PCM connector terminals D6 and B20 or B22.
Is there voltage?
YES - Repair open in the wire between PCM connector terminal D6 and the transmission range switch.
NO - Go to step 9.
9. Shift to P and N position.





10. Measure the voltage between PCM connector terminals B14 and B20 or B22.
Is there voltage?
YES - Repair open in the wire between PCM connector terminal B14 and the transmission range switch.
NO - Go to step 11.
11. Shift to D3 position.





12. Measure the voltage between PCM connector terminals D8 and B20 or B22.
Is there voltage?
YES - Repair open in the wire between PCM connector terminal D8 and the transmission range switch.
NO - Go to step 13.
13. Shift to 2 position.





14. Measure the voltage between PCM connector terminals D14 and B20 or B22.
Is there voltage?
YES - Repair open in the wire between PCM connector terminal D14 and the transmission range switch.
NO - Go to step 15.
15. Shift to 1 position.





16. Measure the voltage between PCM connector terminals D15 and B20 or B22.
Is there voltage?
YES - Repair open in the wire between PCM connector terminal D15 and the transmission range switch.
NO - Check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and recheck.
