Normal Operation
The power liftgate (PLG) module communicates information requested by a scan tool over the international standards organization (ISO) network. The ISO network provides communication between the data link connector (DLC) and the scan tool through a single wire, circuit 70 (LB/WH). The ISO network does not permit inter-module communication. The scan tool initiates communication with the module undergoing testing, allowing transmission of diagnostic data to the scan tool through the DLC.

Possible Causes
- Fuse(s)
- Circuit 1460 (RD/YE) open
- Circuit 1052 (TN/BK) open
- Circuit 2064 (RD/LB) open
- Circuit 1205 (BK) open
- Bussed electrical center (BEC)
- Smart junction box (SJB)
- PLG module
