Power Liftgate (PLG) Control Module Inspection: Notes
- Remove the trunk side trim.
- Verify that the voltages of each of the terminals are as indicated in the terminal voltage table (reference).
- If the voltage is not as specified in the terminal voltage table (reference), inspect the parts under Inspection item(s) and related wiring harnesses.
- If the system does not work normally even though the inspection items are normal, replace the power liftgate (PLG) control module.
- If the voltage is not as specified in the terminal voltage table (reference), inspect the parts under Inspection item(s) and related wiring harnesses.
