I have a 5a fuse and having the issue of randomly sometimes having the led on in high mode after shutting off the car and locking it
I tried to recreate right now and it won’t do it. So I’m thinking it has something to do with being dark outside and having the auto lights on but will try again tonight and see if I can recreate once it gets dark
Okay having had the new lights installed a week, have witnessed this.
I stood around for 11 minutes... long enough for the power to shutoff to the USB ports, and the DRLs were still on, in "high" brightness mode.
Un/locking, opening/closing the door had no impact. The only way to get them to shut off, was to temporarily turn on the ignition. (didn't start the engine)
This is how I recreated the issue. (doesn't matter whether it's night or day)
1) Park the vehicle. (in reverse gear with
clutch pedal floored)
2) Opened only the driver door.
3) Shut off the engine.
(following done within 10 seconds...)
4) Lock the vehicle.
5) Get out.
6) Shut the door.
Many steps may be unnecessary. I believe the key is basically to shutoff the vehicle with the driver door open. There could be other ways to reproduce this.
But it's apparent that until we can verify that it won't run the battery down, we have to watch for this every time we exit the vehicle. It's possible that this isn't a logic bug... the ECU may be waiting for some feedback from an (absent) component that would've been powered by F26. Haven't verified whether this behavior can be reproduced with anything other than the driver door. But I suspect it requires the driver door.
