PINPOINT TEST Y: NO COMMUNICATION WITH THE POWER LIFTGATE MODULE

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

Possible Causes
- circuit 1460 (RD/YE) open
- circuit 2064 (RD/LB) open
- circuit 1205 (BK) open
- BEC
- SJB
