My CT wouldn’t unlock when approaching from the rear so when poking around in service mode on my I saw this. Requested a service appt and apparently it needs a part??
Yes. Would not recommend going into service mode, though.
Why? Serious question.
Probably a disconnected wire between the ECUs and the low power Bluetooth module. Fixed a cut wire once, went away.
The customers typically end up viewing a bunch of non-customer facing alerts, in turn, making them think they have all these issues. When in reality, all you would need is the customer-facing alert and the timestamp of said alert/s to have service properly diagnose the concern
It can be the component or the wiring (unpluged, cut, torn, rodents).
I get there are a bunch of meaningless errors, but in this case I noticed a change in behavior, which is why I went looking. They just replaced the rear bumper facade so they probably did something there like pinched a wire or left it unplugged!
Yep, for me it was water ingression on the right bluetooth of an M3
This is 100% correct. Modern vehicles have so many computers and things on their CANBUS that have their own nuisance messages that are not meant for customers. Hard faults are the only worry.
What was the fix for it?
Thanks.
you may be able to figure out what may have been disconnected looking at the bumper cover procedure. All service manuals and procedures are at service.tesla.com. Super informative
Replacing the right B pillar trim (which includes the trim, the bluetooth and camera model), and reinstall aoftware from service mode.
Replace the part with part #NAZI76498
I scheduled a service appt since it is still under warranty. They recently replaced the rear bumper fascia, so this info makes me confident they either pinched a wire or just didn’t reconnect the ECU on reassembly.
