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 anti-lock brake system (ABS) module (if equipped). Voltage for the parking aid module is provided by circuit 294 (WH/LB). Ground is provided by circuit 57 (BK).

Possible Causes
- Fuse
- Circuit 70 (LB/WH) open
- Circuit 294 (WH/LB) open
- Circuit 57 (BK) open
- Parking aid module
