PINPOINT TEST L: THE PARKING AID MODULE (PAM) DOES NOT RESPOND TO THE SCAN TOOL

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

This pinpoint test is intended to diagnose the following:
- Fuse
