P1706

DTC P1706: Open in Transmission Range Switch Circuit (no gear position inputs)

NOTE: Record all freeze data 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 the B20 and B22 terminals and body ground.
Is there continuity?
YES - Go to step 4.
NO - Repair open in the wires between the B20 and B22 terminals and ground (G101), or repair poor ground (G101).
4. Turn the ignition switch ON (II).
5. Shift to D4 position.





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





8. Measure the voltage between the D6 and B20 or B22 terminals.
Is there voltage ?
YES - Repair open in the wire between the D6 terminal and the transmission range switch.
NO - Go to step 9.
9. Shift to P or N position.
10. Measure ATP NP voltage between these terminals:
- '98-99 models: Between terminals D13 and B20 or B22.
- '00-02 models: Between terminals B14 and B20 or B22.





'98-99 models:





'00-02 models:

Is there voltage?
YES - Repair open in the wire between the D13 ('98-99) or B14 ('00-02) terminal and the transmission range switch.
NO - Go to step 11.
11. Shift to D4 position.





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





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





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