P1705
DTC P1705: Short in Transmission Range Switch CircuitNOTE: Record all freeze data and review General Troubleshooting Information before you troubleshoot.
1. Turn the ignition switch ON (II).
2. Shift to all positions other than R.
3. Measure the voltage between PCM connector terminals D6 and B20 or B22.
Is there battery voltage?
YES - Go to step 4.
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 and B22 and body ground (G101). If the wires are OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and recheck.
4. Shift to all positions other than P or N.
5. Measure the voltage between PCM connector terminals B14 and B20 or B22.
Is there about 5 V?
YES - Go to step 6.
NO - Check for a short in the wire between PCM connector terminal B14 terminal and the transmission range switch. If the wires are OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and recheck.
6. Shift to all positions other than D.
7. Measure the voltage between PCM connector terminals D9 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 D9 and the transmission range switch or A/T gear position indicator. If the wire is 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 D3.
9. Measure the voltage between PCM connector terminals D8 and B20 or B22.
Is there battery voltage?
YES - Go to step 10.
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 the wires are OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and recheck.
10. Shift to all positions other than 2.
11. Measure the voltage between PCM connector terminals D14 and B20 or B22.
Is there battery voltage?
YES - Go to step 12.
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 the 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 1.
13. Measure the voltage between PCM connector terminals D15 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 recheck.
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 the wires are OK, check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and recheck.
