I had my rear end replaced and shortly after that my TCS started acting funky. Until I get it fixed, I just pulled the fuse to the system and want to eliminate all of the DTCs I’m getting. I've already adjusted all of the TCS related DTC enablers and MILs, but I'm still getting the following two DTCs and my error lamps for "break, TCS, and ABS" are still lit up.

C0245 "Wheel Speed Sensor Frequency Error" C ($28 "Traction Control System or Electronic Brake Control Module (EBCM)"

C0121 "Valve Relay Circuit" C ($28 "Traction Control System or Electronic Brake Control Module (EBCM)"


What have I missed?
