Power Trunk / Liftgate Control Module: Testing and Inspection

POWER LIFTGATE (PLG) CONTROL MODULE INSPECTION

1. Measure the PLG control module terminal voltage.

2. If there is large difference between the measured value and the value in the terminal voltage table, inspect the parts under "Inspection item(s)" and related wiring harnesses.

- If the system does not work properly even though the inspection items or related wiring harnesses do not have any malfunction, replace the PLG control module.
