Did you have a Toyota dealership scan for error codes?
They can do more than a regular scanner can.

 

Yes took to dealer - codes they got seemed strange as related to the brake problem when I looked them up...from dealer’s printout:
“C1422, C1425- open in stop light switch circuit - found open in stop light switch and open in stop light relay - due to water leak on pass side. Need to replace stop light switch and relay. $170 stop lamp relay, $65 stop lamp switch.”

They gave me a diagram saying they recommend I locate and fix the water leak 1st, but the diagram they provided showed the fuse box that is inside the car under the driver’s side dash.

I have looked up stop light switch and relay online and aren’t sure what they are referring to. I see the relays on the drivers side under hood 1 says “brk” and 2 say ABS but there are none related to brake system on the passengers side from what I can see.

Pls advise. Thanks

 

Hi Damdamravowner143, I know this is a long shot.....did you fix your issue? I have the same issue and trying to fix this myself. Any information will be appreciated more than you know! Cheers!
