Help and service advice with a ghost problem (1 Viewer)

Hi everyone! So long story short the other morning I started the car, drove off and I noticed that all the traction control lights were on along with my airbag light. The following things also stopped working at the same time... ( i assume its all related)

1. Side mirrors not working (failed in the down "reverse" position)
2. First 4 buttons of the Nav display. (display stays off but can still hear beeps when I press any of the first 4 buttons) The last 3 buttons all work and they bring the display on. AC works.
3. Locks do no not work.
4. Power windows do not work.
5. Key fob lock/unlock does not work. It will not actuate the door locks nor does it even beep!

Seems to me something blew or failed that ties into all these systems. Does the GX route a lot of electrical systems through the navigation unit? If so can it be the culprit? Do you guys think that the mirrors being (failed) in the down position might be a clue to the fact something happened when I placed the car in reverse?

2006 GX -There are no engine codes or anything like that. I am at a complete loss. (PS i had this on GXOR FB group but it was deleted because I had no engine codes so I couldn't get the help I need)

Anyway any help or wisdom is greatly appreciated.

Stefan

Also forgot to ask if anyone knows a good shop in the Victorville SOCAL area if it comes to it?

Without the fuse guide in front of me, I can't comment on whether or not there is a dedicated relay or fuse that covers each of the items you described. I will say Lexus did seem to put a lot of seemingly unrelated items in the same fuse circuit (ie, the sunroof and telescoping steering wheel motor are in the same circuit which makes zero sense to me).

It stands to reason that all your items are related.

I would take each fuse panel (under the hood and under the dash) and start going through fuses one by one looking for any blown fuses. After that, I would start checking relays. Those are a bit tougher as they don't have a way to see if they're blown. With relays, I just find another circuit that uses the same type of relay and swap the two and check that the items still function. It's tedious but works if you don't have a voltmeter and the skill to test relays

In case anyone runs into this post with very similar issues, like I did, the blown fuse ended up being ECU B under the hood

yeah, that is all ECU-B or a failing battery
