Test D: The Power Liftgate Does Not Operate Correctly - Reverses During The Power Close Operation

PINPOINT TEST D: THE POWER LIFTGATE DOES NOT OPERATE CORRECTLY - REVERSES DURING THE POWER CLOSE OPERATION

Normal Operation
When the power liftgate (PLG) moves in the close direction, the PLG module monitors the pinch strips and position sensor for obstacle detection. The PLG module uses a 5-volt reference signal on circuit CPR52 (YE/VT) and a return signal on circuit RPR52 (VT/GY) for the left pinch strip. The PLG module uses a 5-volt reference signal on circuit CPR51 (YE/OG) and a return signal on circuit RPR52 (VT/GY) for the right pinch strip. The right and left pinch strip return signal circuits are spliced together.

- DTC B107D Obstacle Detected While Closing - If during self-test, an obstacle is detected during powered open/close the PLG module will set this DTC.
- DTC B2419 Sensor 1 Invalid - If sensor signals are not in correct phase, the Hall effect sensor may be defected or have reverse connections between Hall effect sensors 1 and 2, and the PLG module will set this DTC.
- DTC B2420 Sensor 2 Invalid - If sensor signals are not in correct phase, the Hall effect sensor may be defected or have reverse connections between Hall effect sensors 1 and 2, and the PLG module will set this DTC.

This pinpoint test is intended to diagnose the following:
- Mechanical binding
- PLG latch striker alignment
- PLG latch
- Position sensor
- PLG module
- Wedges
- Wiring, terminals or connectors
