So here's the full story.

I was trying to program a new TPMS sensor. I got a cheap xhorse cable from amazon and was using Techstream to program the dang thing. It didn't work. I kept throwing an error stating "is registration failed due to a communication error with the WCU while in Initialization mode" and "terminate initialization by connecting tc and cg of the dlc3 for 30 seconds"

So I tried to terminate those and it wasn't working. So I then, tried to terminate other pins nearby incase I got it wrong. Yes I know that was stupid of me. Now my car has the ABS, Brake and VSC light on. Also when I pull the codes in Techstream, it has a C1203 code. When I try to clear the code it doesn't clear and it just stays.

So, I was wondering if you guys know what I can do to fix this. I seen some guy on youtube did a "Zero Point calibration"?

Do you think this might help?

Could I have damaged my ECU by poking the wrong obd2 connector pins?

C1203: Code Meaning, Causes, Symptoms, & Tech Notes

The circuit is used to send TR(A)C and VSC information from the skid control ECU to the power management control ECU, and hybrid control system

So what should I do?

 

Could I have blown a fuse? Which fuse, if any could cause the ABS, Brake and VSC light to go on and stay on?

 

Does this screenshot of TechStream Tools

help

 

Anyone?

 

So this is the Mechanical section. I was under the impression that someone on the forum could help another person on the forum with mechanical advice, other than "go to a mechanic".

If there are any knowledgeable people willing to share their knowledge, I would greatly appreciate it.

 

You are correct, however, there may be no one on here that would be able to answer your question. Just because there is a specific subforum for our vehicle does not guarantee we'll get a helpful answer. I've mentioned it before, but Rav4 owners - for the most part - are not necessarily motorheads so complex questions may take a long time to get answered - if at all. This vehicle is not high on a motorhead's list and the Rav4 is marketed to a different group. So the best answers may be to continue searching the internet or take it to a mechanic.

 

Thanks for the honest answer.
