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. Observe the A/T gear position indicator, and shift to each position.
Do any indicators stay on when the shift lever is not in that position?
YES-Go to step 3.
NO-Go to step 4.
3. Clear the DTC, test-drive the vehicle, and recheck for DTC P1705.
Does the OBD II scan tool indicate code P1705?
YES-Review the freeze data. If the freeze data indicates more than one gear position indicator on at one time, go to step 4.
NO-Intermittent failure; wiggle the wire harness and check for an intermittent short to ground.
4. Disconnect the transmission range switch connector.
Do all gear position indicators go out?
YES-Replace the transmission range switch.
NO-Turn the ignition switch OFF, then go to step 5.
5. Test the transmission range switch.
Is the switch OK ?
YES-Go to step 6.
NO-Replace the transmission range switch.
6. Connect the transmission range switch connector.
7. Turn the ignition switch ON (II).
8. Shift to any position other than R.
9. Measure the voltage between TCM connector terminals All and A4 or A17.
Is there about 10 V?
YES-Go to step 10.
NO-Check for short in the wire between TCM connector terminal All and the transmission range switch or A/T gear position indicator, and check for an open in the wires between TCM connector terminals A4 and A17, and ground (G101). If the wires are OK, check for loose terminal fit in the TCM connectors. If necessary, substitute a known good TCM and recheck.
10. Shift to any position other than [P] and [N].
11. Measure the voltage between TCM connector terminals A10 and A4 or A17.
Is there about 5 V?
YES-Go to step 12.
NO-Check for short in the wire between TCM connector terminal A10 and the A/T gear position indicator, and check for short in the [P] and [N] position wires between the gauge assembly and the transmission range switch. If the wires are OK, check for loose terminal fit in the TCM connectors. If necessary, substitute a known-good TCM and recheck.
12. Shift to any position other than [D].
13. Measure the voltage between TCM connector terminals A9 and A4 or A17.
Is there about 5 V?
YES-Go to step 14.
NO-Check for short in the wire between TCM connector terminal A9 and the transmission range switch. If the wire is OK, check for loose terminal fit in the TCM connectors. If necessary, substitute a known-good TCM and recheck.
14. Shift to any position other than L.
15. Measure the voltage between TCM connector terminals A7 and A4 or A17.
Is there about 10 V?
YES-Check for loose terminal fit in the TCM connectors. If necessary, substitute a known-good TCM and recheck.
NO-Check for short in the wire between TCM connector terminal A7 and the transmission range switch or A/T gear position indicator. If the wire is OK, check for loose terminal fit in the TCM connectors. If necessary, substitute a known-good TCM and recheck..
