For a complete wiring diagram Refer to Section 8W
- 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.
| Possible Causes |
| (Q78) RIGHT PINCH SENSOR SIGNAL CIRCUIT SHORT TO GROUND |
| (Q78) RIGHT PINCH SENSOR SIGNAL CIRCUIT SHORT TO (Q901) LOGIC GROUND CIRCUIT |
| RIGHT LIFTGATE PINCH SENSOR |
| POWER LIFTGATE MODULE |
Diagnostic Test
NOTE: The vehicle should be at room temperature when this test is performed.
1. DTC PRESENTWith 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. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).
2. RIGHT LIFTGATE PINCH SENSOR SHORTED
Disconnect the Right Liftgate Pinch Sensor harness connector
