Hello there, I am new to this Forum. I own a 2014 C250 Coupe, with 21K miles. The car had been in our garage for 2 weeks without use. Took the car out and upon ignition, the ABS innoperable and Check engine light were iluminated on the dash. I used my OBDII sensor and It's showing a C0031 error, indicating a left ABS sensor malfunction. I replaced the sensor without any major issues, I cleared the error code, and when switching the ingnition, the ABS innoperable message persists, check engine light is off. I checked all fuses and all tested OK. Besides checking the sensor for continuity, resistance and AC voltage when turning the wheel, is there something else that I need to be looking for as the culprit? Thank you in advance for your assistance and tips.
