For a complete wiring diagram Consult Diagrams/Electrical

- When Monitored:
Whenever the Power Liftgate Module is awake.

- Set Condition:
The Power Liftgate Module has detected the Right Liftgate Pinch Sensor circuit voltage is under 0.5 volts for over 20 seconds.





Diagnostic Test

NOTE: The vehicle should be at room temperature when this test is performed.

1. DTC PRESENT
With the scan tool, record DTCs and any liftgate inhibitors.
Erase DTCs.
Turn the ignition off, wait 10 seconds, then turn the ignition on.
Operate the liftgate several times.
With the scan tool, read DTCs.
Does the scan tool display B1947-POWER LIFTGATE PINCH SENSOR 2 CIRCUIT LOW?

Yes

- Go To 2

No

- Using the wiring diagram/schematic as a guide, inspect the wiring and connectors for an intermittent condition.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.

2. RIGHT LIFTGATE PINCH SENSOR SHORTED




Disconnect the Right Liftgate Pinch Sensor harness connector
Erase DTC's
Turn the ignition off, wait 10 seconds, then turn the ignition on.
With the scan tool, read DTCs.
Does the scan tool display B1947-POWER LIFTGATE PINCH SENSOR 2 CIRCUIT LOW?

Yes

- Go To 3

No

- Replace the Right Liftgate Pinch Sensor.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.

3. (Q78) RIGHT PINCH SENSOR SIGNAL CIRCUIT SHORT TO GROUND




Turn the ignition off.
Disconnect the Power Liftgate Module C2 harness connector.
Measure the resistance between ground and the (Q78) Right Pinch Sensor Signal circuit.
