Good evening,
I recently installed a traction control button for my 2017 Jetta SE (US), but i can't seem to get it to work. I purchased OBDEleven Pro and went through the suggested long coding changes from 2 different sites (one where I bought the switch) as well as some random guy on youtube - none of them made any difference.
My long code from my brake module:
A14B400C492A0000850B02E8922200402110F012
The two manufacturers sites suggested I change byte 17 to '18' (originally '10'), and then change byte 19 (originally '12') to '22' (I bolded those bytes above).
The youtube fella was changing bytes 17 and 19 in his central electronics module - It seemed harmless so I tried it and it didn't work so I changed it back to the original. I think he was confused and working in the wrong module, but at this point I'm confused too...so
When I push the traction control button, I get no indication of anything changing with any of the changes above.
Any thoughts? Am I crazy? I'm not a car guy, but I am an electronics guy (bits, bytes, and hex are right up my alley). The pin is in the correct spot on my ABS module and I made sure it clicked into place (I verified it, though I may go back there and triple-check just to make sure i'm not losing it).
Is there a way for me to check with OBDEleven that the ABS module is registering my button push?
I appreciate any help!
Thanks,
Brandon
