I thought the speedo ran from a sensor on the rear of the transmission, I am not really to sure on that though.
Brake light stop switch has been known to put the ESP/BAS light on. No cruise control with speedo issues either.
I only had the p0600 code thrown initially for the serial communication. When i took it for a drive after changing the sensors out the check engine light didnt come back on until the 3rd key cycle of on and off. I haven't seen what the check engine light code is since the reset but i will get my scanner and go take a look. I know its horrible practice but im ready to just start replacing parts till i solve the problem. I read on another post about the abs module potentially being a problem. Any thoughts with that?
