Display day/night mode does not work
WARNING: This page is about a different car, the 2008 Honda Pilot, 2007 Honda Pilot, and 2006 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- Check the display setting.
- Always check the connectors for poor connections or loose terminals.
- Before troubleshooting, make sure you have the navigation system anti-theft codes.
- After troubleshooting, enter the navigation system anti-theft codes.
- Full brightness on 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 under Set-up to "Auto" and recheck.
Does the display change to day and night modes when turning the headlight on and off?
YES - 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 - The system is OK.
NO - Check the ILL+ circuit between the navigation unit and No. 10 (15 A) fuse in the passenger's under-dash fuse/relay box. If OK, substitute a known-good navigation unit and navigation display unit one at a time, in this order. Recheck the system operation after each unit substitution until the problem is resolved, then replace the malfunction unit.
