Display Day/Night Mode Does Not Work

NOTE:
  • Always check the connectors for poor connections or loose terminals.
  • Before troubleshooting, get the navigation system anti-theft codes.
  • After troubleshooting, enter the navigation system anti-theft codes.
  1. Change the day/night mode under Set-up to AUTO, and recheck.

    Does the display change to day and night modes using the headlights? 

    1. YES  - The system is OK at this time.
    2. NO  - Go to step 2.
  2. Go into the Diagnostic Mode and use the "Car Status" diagnostic to check for an ILL signal (see CAR STATUS ).

    Is the "ILL" signal OK? 

    1. YES  - The system is OK.
    2. NO  - Check the ILL+ circuit for an open or short to ground between navigation unit connector A (20P) terminal No. 5 and passenger's under-dash fuse/ relay box connector I terminal No. 2. If OK, substitute a known-good navigation unit and recheck.
