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 [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. Shin 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 [R] 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.
