Normal Operation
The parking aid module communicates with the scan tool through the ISO 9141 communications network. Circuit 70 (LB/WH) provides the network connection to the parking aid module. The parking aid module shares the ISO 9141 network with the restraints control module (RCM) and the luggage compartment lid module (if equipped). Voltage for the parking aid module is provided by circuit 1003 (GY/YE). Ground is provided by circuit 676 (PK/OG).

Possible Causes
- Fuse
- Circuit 70 (LB/WH) open
- Circuit 676 (PK/OG) open
- Circuit 1003 (GY/YE) open
