ABS/Traction control lights stay on

*2010 V6 Tacoma 4x4 TRD Sport*

So I just finished a cross-country trip from Cali to Miami. When I arrived, I removed my camper shell, which I had connected to the left brake light so that the brake light on the shell could function properly during the drive. Unfortunately, upon disconnect, the two wires coming out from the brake light assembly touched and fried something.

My rig won't get out of park without me depressing the override button next to the shifter and the ABS and traction control lights stay on while driving.

I just jumped the OBD and got code 46 from the ABS light blinking. I couldn't get the codes to reset regardless of how many times I tapped the brakes.

From what I've read, it could either be one (or more) of the ABS speed sensors or even the master cylinder pressure sensor.

I would love to minimize the trial-and-error phase of this repair (especially since these components are $200+).

If anybody has had a similar experience or any advice on how to proceed, it would be greatly appreciated.

Cheers,

Lu

 

You don't mention having checked fuses.

And if you did, visual doesn't always work on these minis. A continuity test is a better way.

 

I visually checked all the fuses, but you are right, I should bust out the ole multimeter and check them that way...thank you Bill. Will update one way or the other once done.

 

Confirm that your brake lights aren’t working, and then change your blown “Stop” fuse. The brake light circuit is also an input to the ABS module, and if that input is missing you’ll have an ABS fault (like you have) along with your other symptoms.

 

I would add testing the brake switch to that list.

 

The stop fuse is in the under hood fuse box. 100% guaranteed that is your only problem.

 

WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!

Multimeter found that the 10 amp STOP fuse was blown. Replaced it, then re-jumped the OBD. This time I was able to reset the code and now no lights!

Thank you again, Bill!

 

You nailed it, Muddin!

 

You know what that means? Take that $200 you were afraid you would spend on the repair and buy yourself a case of beer and relax for the rest of the day

 

hahaha...I like where your head's at. Done and done!
