Normal Operation
The anti-lock brake system (ABS) module supplies the vehicle speed signal (VSS) to the navigation system module through circuit 8-CF63 (WH/GN). The navigation system uses the VSS signal and the global positioning system (GPS) antenna to establish vehicle speed and position.

Possible Causes
- circuit 8-CF63 (WH/GN) open or shorted to ground
- GPS antenna
- audio unit
- navigation system module
- anti-lock brake system (ABS) module
