Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** you trying to make repair yourself or just want to know what to expect at shop? Thanks.
This could be a few different problems so testing will be required before knowing exactly what part has failed. Would you like testing instructions?
This code could be caused by a failed brake light switch, wiring, or brake actuator assembly. Without testing you would just be guessing which could end up costing alot of money to replace good parts just to find out wiring is the problem. Did shop ask you to order part or did you just check codes and trying to buy part to save money?
I'd recommend bringing vehicle to a different shop or dealership. If mechanic gave you no information other then C1422 then I don't think he knows what he is doing. Like I said, this code can mean many things. Here are troubleshooting steps that mechanic SHOULD have done to figure out what part is bad then he would have been able to tell you actually part vs diagnostic code. I could easily give you a part number and link to some part but I don't want you to waste your money replacing good parts. Let me know if you have more questions, thanks.
Here are rest of instructions that you may want to print off and give to your mechanic so he can do proper testing. let me know if you have more questions, thanks.
