NOTE:

- Full brightness on with the headlights on (there is a separate dimmer mode for night and day) the instrument panel brightness control causes the system to stay in the day mode, even when the lights are on.
- Turn the ignition switch ON (II).
- Make sure the instrument panel brightness control is not on full brightness. Turn the headlights on, and adjust the dash brightness to the middle range.
- Change the day/night mode to AUTO under Set-up and recheck.
Does the display change to day and night modes when turning the headlights on and off?
YES - Intermittent failure. The system is OK at this time.
NO - Go to step 4.
- Go into the Diagnostic Menu and use the "Car Status" test to check for an ILL signal (see CAR STATUS
).
Is the "ILL" signal OK?
YES - Substitute a known-good display unit and recheck the symptom. If the problem goes away, replace the original display unit. If the problem does not go away, replace the gauge control module.
NO - Check the ILL+ circuit between the navigation unit and relay module.
