Normal Operation
The anti-lock brake system (ABS) module supplies the vehicle speed signal (VSS) to the navigation 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, short to ground or short to voltage
- GPS antenna
- audio unit
- navigation module
- ABS module
