For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams.
- When Monitored:
Whenever the Power Liftgate is power closing.
- Set Condition:
When the Power Liftgate Module senses no current on the (Q89) Liftgate Close Driver circuit and no liftgate movement, this code will set. It is also possible for this code to set if the liftgate has been run several times and the internal circuit breaker (Thermo Protection Device) in the Power Liftgate Drive Unit has opened up.
