2015 Mustang W/Retrofit Sync 3 Passive Battery Drain

Ford SYNC 3 Support

Early 2021, I updated my retrofitted Sync3 unit to 3.4.20282. Since then I have had passive battery drain while the car is off. I have done the fix listed in FAQ / Common Issues Thread (READ THIS BEFORE POSTING!) . Any suggestions on things I could fix? The Discord indicated it could be bad AsBuilt information since I have a retrofit. Also I bought the retrofit kit from 4D-tech in 2017 if that helps at all.

Do you have a error message, if so what is it?

No longer exists, but this is independent of the actual updating I think.

Your asbuilt is incorrect for:
7D0-01-01.
You have 6222 0102 22xx
You should have 622A 0102 22xx.
2015 Mustang is CGEA 1.3 and uses the BCM for Clock Master.
Return the Illumination Gateway to CGEA.

Thanks for the quick analysis!

I’ve applied the changes called out in your message and taken it off the tender for the night. Will check it in a day to see if the drain has gone away.

I am a bit suspicious about the 7D0-06-01 *XXX setting as I think that controls the G-meter thing that I never use, but I’ll be unable to test that before spring as it is too cold here for the tires on the car.

That is the internal gyro for the nav and is used for positioning whether you have nav or not. NON-NAV and NAV are different settings.
