DTC P1705: Short in A/T Gear Position Switch Circuit

NOTE: Record all freeze data before you troubleshoot.

1. Turn the ignition switch ON (II).
2. Observe the A/T gear position indicator, and shift each position separately.
Do any indicators stay on when the shift lever is not in that position?
YES-Go to step 3.
NO-The system is OK at this time. Check the wire harness for damage.
3. Disconnect the A/T gear position switch connector.
Do all gear position indicators go out?
YES-Replace the A/T gear position switch.
NO-Go to step 4.
4. Turn the ignition switch OFF, and connect the A/T gear position switch connector.
5. Turn the ignition switch ON (II).
6. Shift to all positions other than [R].





7. Measure the voltage between PCM connector terminals D6 and B20 or B22.
Is there battery voltage?
YES-Go to step 8.
NO-Check for a short in the wire between PCM connector terminal D6 and the A/T gear position switch or A/T gear position indicator, and check for an open in the wires between PCM connector terminals B20 and B22 and body ground (G101). If wires are OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known good PCM and recheck.
8. Shift to all positions other than [P] or [N].





9. Measure the voltage between PCM connector terminals B14 and B20 or B22.
Is there about 5 V ?
YES-Go to step 10.
NO-Check for a short in the wire between PCM connector terminal B14 and the A/T gear position switch, and in the [P] and [N] position signal wires between the A/T gear position indicator and the A/T gear position switch. If necessary, substitute a known-good PCM and recheck.
10. Shift to all positions other than [D4].





11. Measure the voltage between PCM connector terminals D9 and B20 or B22.
Is there about 5 V ?
YES-Go to step 12.
NO-Check for a short in the wire between PCM connector terminal D9 and the A/T gear position switch. If wires are OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and recheck.
12. Shift to all positions other than [D3].





13. Measure the voltage between PCM connector terminals D8 and B20 or B22.
Is there battery voltage?
YES-Go to step 14.
NO-Check for a short in the wire between PCM connector terminal D8 and the A/T gear position switch or A/T gear position indicator. If wires are OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and recheck.
14. Shift to all positions other than [2].





15. Measure the voltage between PCM connector terminals D14 and B20 or B22.
Is there battery voltage?
YES-Go to step 16.
NO-Check for short in the wire between PCM connector terminal D14 and the A/T gear position switch or A/T gear position indicator. If wires are OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and rechecked
16. Shift to all positions other than [1].





17. Measure the voltage between PCM connector terminals D15 and B20 or B22.
Is there battery voltage?
YES-Go to step 18.
NO-Check for a short in the wire between PCM connector terminal D15 and the A/T gear position switch or A/T gear position indicator. If wires are OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and recheck.
18. Shift to all positions other than [N].





19. Measure the voltage between PCM connector terminals D4 and B20 or B22.
Is there battery voltage?
YES-Check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and rechecked
NO-Check for a short in the wire between PCM connector terminal D4 and the A/T gear position switch or A/T gear position indicator. If wires are OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and recheck.
