Change Clock on Accord, Odyssey, or Pilot with Navigation – Repair

At the start of the new year, drivers may have noticed their clocks changed and now show an incorrect time and/or year. At this time, there is only a fix available for the clock, not the date.

The clock issue is specific to the models below with navigation systems. The clock shows the incorrect time. This issue is due to a limited GPS receiver capacity resulting in “rollover” of the internal chip memory; the rollover occured on January 1, 2022 at 12:00AM local time. As a result, once specific triggers are met, the navigation date and time will be incorrect. However, the year cannot be corrected at this time.

Affected Vehicles:

• 2006-12 Accord Coupe and Sedan 
• 2010-12 Accord Crosstour 
• 2006-07 Accord Hybrid 
• 2005-11 Odyssey
• 2006-11 Pilot 
• 2006-14 Ridgeline – No working fix for Ridgeline at this time

Can the date be adjusted to the correct value manually? 

After January 1, 2022, when the system internal calendar is reset to May 19, 2002, the date will always be incorrect and stay incorrect. There is no solution to correct it. 

Can the digital Radio/LCD time be adjusted to the correct value manually? 

Follow the steps below from January 1, 2022, to August 16, 2022, to adjust the time during this period. 

NOTE: 

• You must do this at the specific time, or the update will not happen. 
• Verify both the Navigation and Radio code are available before disconnecting the battery.
• 2006–14 Ridgeline units are NOT included in this process.

1. Disconnect the vehicle’s battery Negative (-) terminal first, followed by the Positive (+) terminal at the exact local time of 12:40 AM/PM. 

2. With an accurate source of time to compare to, reconnect the Positive (+) terminal followed by the Negative (-) terminal at exactly 1:00 AM/PM.

3. Turn the vehicle on in Accessory Mode and enter both the Navigation and Radio codes. The digital LCD clock will now keep time from 1:00 AM/PM local time. 

On or after August 17, 2022, when the system’s internal calendar recalibrates, the GPS time signal becomes valid again. The clock will show the correct GPS time but most likely be off by 1 hour because the system’s internal calendar interprets the daylight saving time (DST) change incorrectly. 

Now, the customer can adjust the time correctly, and it won’t be affected every time the vehicle’s power is cycled off and then on. The correct time will stay on through the next DST change based on the system internal calendar. 

What can we do to avoid the time changes to incorrect value again after August 17, 2022? 

The automatic DST function will not work properly causing the incorrect time at the perceived DST date. We recommend that after August 17, 2022, the customer sets the “Auto Daylight Saving” function to “OFF” and adjust the DST manually.
