Dash light cause and fix

Does anyone else have this problem, if so what’s the cause and how did you fix??

Backstory: I was driving to work yesterday morning and all four of these light just lit up randomly at once. Got to my station and cranked it up this morning and the abs, traction control off light were off but the rear lock light was still on, and was dim. Drove for about 5 minutes and the abs and traction light flashed and then stayed on. Arrived home and all lights are still on. (Rear lock is not on)

2015 Tacoma

 

If the IG1 No 2 fuse on the interior fuse panel trips, similar lights light up. A blown fuse wouldn't explain the lights coming on and then going off, but maybe worth having a look at.

 

Is your truck 4wd or 2wd?

 

It is a 2wd!

 

On a 2wd it's possible the locker is engaged, have you tried cycling the diff lock button?

If that doesn't work go to the rear axle and unplug the detection switch and see if the locker light goes out.

 

I checked that as well to make sure I wasn’t going crazy, the rear locker is not engaged. I did unplug it yesterday and they were still there.

 

So we either have a wiring issue or a module issue.

I'd say try unplugging the 4wd ECU first and see if locker light goes out, if not unplug the ABS module and see if it goes out.

 

Where is that located since mine isn’t 4wd?

 

Same spot above the glovebox to the right, just a single connector on a 2wd though.
