Normal Operation
The parking aid module communicates with the scan tool through the International Standards Organization (ISO) 9141 communications network. Circuit 70 (LB/WH) provides the network connection to the parking aid module. The parking aid module shares the ISO network with the restraints control module (RCM) and the four wheel drive (4WD) control module. Voltage for the parking aid module is provided by circuit 295 (LB/PK). Ground is provided by circuit 57 (BK).
