Normal Operation
The navigation module receives the vehicle speed signal from the powertrain control module (PCM) through circuit 679 (GY/BK). The navigation system uses the vehicle speed signal and the global positioning system (GPS) antenna to establish vehicle speed and position.

Possible Causes
- circuit 679 (GY/BK) open, or short to ground
- luggage compartment lid module
- navigation module
- parking aid module
- PCM
