Question How to stop C0245 & C0121 DTC

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 Iím 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?

You can't tune out ABS system using Hp Tuners...its on a seperate computer system and not accesable.

It's EFI but I get your point. Thanks... Suppose I'll just have to live with it until I get the darn thing fixed.
