Error codes and instrument pan

[rdwarrior52]

Hi all,

I was driving home today and all of a sudden I got a several warning lights and pop ups - traction control disabled, abs disabled and maybe more. I couldn’t really pay attention since I was driving on the freeway and then all of a sudden the entire instrument panel went dead. Both digital screens went off, the speedometer went to 0 and the radio turned off. This was for maybe 15-20 seconds and then it restarted but with the amber wrench symbol. I was going to keep driving until I got home but maybe 5 minutes later the same thing happened. This time I pulled over, turned the truck off for a minute and then back on. The wrench stayed but everything powered up and I made it home. I checked the DTCs and got these:

P0557, P1935, P25B0, U0121, U0164, U0212, U023A, U1012

this is a 21 Ranger Lariat.

anyone have any suggestions or ideas? Monday I’m going to take it to a dealer but I’d like to know if anyone has had any experience with this or if it’s still ok to drive for work tomorrow.

There's been a few who've had similar issues and IIRC they were just some weird electrical gremlins. Some had to disconnect the battery for a few minutes and they were fine after that. I'd still bring it to the dealer and let them go through it for peace of mind.

Actually check out this post here. The OP has similar codes on his sheet.

They replaced a brake switch, and the smart data module, reprogrammed the bcm and pcm numerous times. It all came down to a wire short in the harness between the modules under the fuse/relay box under the hood.
