Brake Power Low/Pre Collision Malfunction???

Hey yall! Have these warning messages appeared for you before and what did you do to resolve them? Any help or advice is greatly appreciated!!

 

Check your brake fluid level. If it's good, I'd guess your electronic brake booster isn't working. Check the fuse for it. If the fuse is good, the whole booster may be f'ed. Edit: Of course, there's more possibilities, this is just a guess.

 

Have you made any recent changes to your truck such as larger tires or a lift? If not then I’d take it to the dealer and let them figure it out; it should be under warranty.

 

Hook up an OBD reader if you can? Some local parts stores do free readings if you don't have one.
Go from there.

I had a brake override malfunction and it told me exactly where the problem was. Throttle body was stuck open.

Good luck

 

I have the same issue.

 

Sorry I’m not a taco guys! but I have been having some issues and there’s a thread on another forum. If you want to hop over and see the mess it’s been, I’ll link it below.

 

Just had this exact same issue in my new 2022 SR5 with 700 miles on it. Thanks for the heads up on what was repaired.

 

Replacing the ABS harness in the rear fixed and got rid of all the lights. Hopefully yours did too.

 

I just had this exact thing happen to my new 22 TRDOR... 2000 miles.

Sounds like it is electronics with the brakes?

Considering this is a brake issue, is it safe to drive to the dealership or does it need to be towed?

 

I had the same issue. my issue was that the rear ABS harness was ripped off from the sensor. Check your ABS harness to see if it’s intact.

 

squirrels....

 

Did you confirm it?

 

I had the same thing, for me it was a shot speed sensor, getting the codes read should tell you for sure.
