TITLE:
Audio-HVAC Subdisplay/ Clock Has Wrong Time
APPLIES TO:
2003-05 Accord EX-Ls and EX V6s with the navigation system.
SERVICE TIP:
Is the time on the audio-HVAC subdisplay/clock not matching the time on the audio-HVAC display module? If this is the case, you need to synchronize
the two clocks. Here's how:
1. Press the SETUP button on the display module. From the Set-up Screen, select 2 or 4. Then select Time zone/clock.
- If the time is off by exactly 1 hour, check if the daylight savings setting is on or if the time zone setting is right for your area.
- If the Set-up Screen time matches the subdisplay/clock time, but both times are wrong, touch the Reset button on the screen. This clears any
adjustments that your customer might have made with the + or - buttons from the Clock adjustment screen.
- If the subdisplay/clock time doesn't match the display module time on the Clock adjustment screen, there could be a communication problem.
Go to step 2.
2. Go into the diagnostic mode (see section 22 of the 2003-2005 Accord S/M for details). Select Functional Setup, and then H/U Time Send. Make
sure you've selected ON, then touch the Set button. You may need to keep doing this last action until the H/U time send completes. If the two clocks
still won't sync, then go to step 3.
3. Check the 10P connector between the subdislay/clock and the display module. Look for loose terminals, and check for any opens or shorts in the
wires. Repair the connector if needed.
