Code C0253 Description

The C0253 diagnostic trouble code (DTC) indicates that there is a malfunction in the Electronic Brake Control Module (EBCM) control valve circuit. The EBCM is a crucial component of the vehicle's anti-lock braking system (ABS) and traction control system. It is responsible for controlling the hydraulic brake pressure during braking to prevent wheel lock-up and skidding.
