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 body ground and PCM connector terminals B20 and B22 individually.
Is there continuity?
YES - Go to step 4.
NO - Repair open in the wires between PCM connector terminals B20, B22 and ground (G101). Repair poor ground (G101).
4. Turn the ignition switch ON (II).
5. Shift to the D5 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 the 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 the P or 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 the D4 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 the D3 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 the 2 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 - Go to step 17.
17. Shift to the N position.





18. Measure the voltage between PCM connector terminals D4 and B20 or B22.
Is there voltage?
YES - Repair open in the wire between PCM connector terminal D4 and the transmission range switch.
NO - Check for loose terminal fit in the PCM connector terminals B14, D4, D6, D8, D9, D14 and D15. If necessary, substitute a known-good PCM and recheck.
