Normal Operation
The power liftgate module communicates with the scan tool through the ISO 9141 communications network circuit 70 (LB/WH). The power liftgate module shares the ISO 9141 network with the restraints control module (RCM), parking aid module, LH power sliding door (PSD) module and RH PSD module. Voltage for the power liftgate module is provided by circuits 1460 (RD/YE) and 2064 (RD/LB). Ground is provided by circuit 1205 (BK).

Possible Causes
- Fuse
- Circuit 70 (LB/WH) open
- Circuit 1205 (BK) open
- Circuit 1460 (RD/YE) open
- Circuit 2064 (RD/LB) open
