Diagnostic Test: Car Status

NOTE:
- Always check the connectors for poor connections or loose terminals.
- Before troubleshooting, get the navigation system anti-theft code.

- If the Previous button on the Trip Computer screen is not active, make sure to answer OK to the Disclaimer screen.

1. Go into the diagnostic mode and use "Car Status" diagnostic to check for a vehicle speed pulse (VSP).

Is there a VSP when the vehicle is moving?

YES - Check the CAN bus wires for an open or short to ground between navigation unit connector A (20P) terminals No. 8 and No. 18 and PCM connector E (31P) terminals No. 15 and No. 26. If OK, replace the navigation unit.

NO - Check the VSP wire for an open or short to ground between navigation unit connector C (8P) terminal No. 6 and PCM connector E (31P) terminal No. 11.
