Ran some wire thru the driver side firewall to the rear of the vehicle and after I was finished my dash was lit up like a Christmas tree. Codes are shown along with the dash. 4LO and Center Diff are flashing along with "check pcs/vsc". The car drives fine, no limp mode or any noticeable difference at all.
The 1 code is for left rear wheel speed sensor failure and I have seen a few threads where owners with faulty speed sensors had these other 2 codes as well. In my case I'm 99% sure it is not the actual wheel sensor but a wire near the steering column I broke, dislodged or pinched while pulling the cable thru the firewall. One time when checking with Techstream I had a DTC for both front speed sensors and not the left rear. I've looked back there in the steering column and cant see anything, but not exactly sure what I'm looking for. Anyone happen to know which wiring harness is for the speed sensors? I have an appointment at the dealer next week, but I'm hoping to get lucky before then because I know if there is just slight damage that could easily be fixed, Lexus is going to just charge me for a new harness.
