P1705

DTC P1705: Short in Transmission Range Switch Circuit.

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

1. Turn the ignition switch ON (II).
2. Disconnect transmission range switch connector.
Do all gear position indicators except 1 go out?
YES - Replace the transmission range switch
NO - Go to step 3.
3. Turn the ignition switch OFF, and connect transmission range switch connector.
4. Turn the ignition switch ON (II).
5. Shift to all positions other than R.





6. Measure the voltage between PCM connector terminals D6 and B20 or B22.
Is there battery voltage?
YES - Go to step 7.
NO - Check for a short in the wire between PCM connector terminal D6 and the transmission range switch or A/T gear position indicator, and check for an open in the wires between PCM connector terminals B20, B22 and body ground (G101). If necessary, substitute a known-good PCM and recheck.
7. Shift to all positions other than P or N.





8. Measure the voltage between PCM connector terminals B14 and B20 or B22.
Is there about 5 V?
YES - Go to step 9.
NO - Check for a short in the wire between PCM connector terminal B14 and the transmission range switch, and in the P and N position signal wires between the A/T gear position indicator and the transmission range switch. If necessary, substitute a known-good PCM and recheck.
9. Shift to all positions other than D5.





10. Measure the voltage between PCM connector terminals D9 and B20 or B22.
Is there about 5 V?
YES - Go to step 11.
NO - Check for a short in the wire between PCM connector terminal DO and the transmission range switch. If necessary, substitute a known-good PCM and recheck.
11. Shift to all positions other than D4





12. Measure the voltage between PCM connector terminals D8 and B20 or B22.
Is there battery voltage?
YES - Go to step 13.
NO - Check for a short in the wire between PCM connector terminal D8 and the transmission range switch or A/T gear position indicator. If necessary, substitute a known-good PCM and recheck.
13. Shift to all positions other than D3.





14. Measure the voltage between PCM connector terminals D14 and B20 or B22.
Is there battery voltage?
YES - Go to step 15.
NO - Check for a short in the wire between PCM connector terminal D14 and the transmission range switch or A/T gear position indicator. If necessary, substitute a known-good PCM and recheck.
15. Shift to all positions other than 2.





16. Measure the voltage between PCM connector terminals D15 and B20 or B22.
Is there battery voltage?
YES - Go to step 17.
NO - Check for a short in the wire between PCM connector terminal D15 and the transmission range switch or A/T gear position indicator. If necessary, substitute a known-good PCM and recheck.
17. Shift to all positions other than N.





18. Measure the voltage between PCM connector terminals D4 and B20 or B22.
Is there battery voltage?
YES - If necessary, substitute a known-good PCM and recheck.
NO - Check for a short in the wire between PCM connector terminal D4 and the transmission range switch or A/T gear position indicator. If necessary, substitute a known-good PCM and recheck.
