Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the B164 Liftgate Position Sensor.
- Test for less than 10 Ω between the low reference circuit terminal E and ground.
- If greater than the specified range, test the low reference circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the K39 Liftgate Control Module.
- Ignition ON, test for greater than 11 V between the 12 V reference circuit terminal A and ground.
- If less than the specified range, test the 12 V reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K39 Liftgate Control Module.
- Ignition OFF, disconnect the X3 harness connector at the K39 Liftgate Control Module.
- Test for infinite resistance between the signal circuit terminal listed below and ground.
- B164 Liftgate Position Sensor - signal circuit terminal C
- B164 Liftgate Position Sensor - signal circuit terminal D
- If not the specified value, test the signal circuit for a short to ground.
- Test for less than 1 Ω between the signal circuit terminals listed below:
- B164 Liftgate Position Sensor - signal circuit terminal C and the K39 Liftgate Control Module - signal circuit terminal 9
- B164 Liftgate Position Sensor - signal circuit terminal D and the K39 Liftgate Control Module - signal circuit terminal 10.
- If greater than the specified range, test the signal circuit for a short to voltage or an open/high resistance.
- If all circuits test normal, test or replace the B164 liftgate position sensor.
