Code C0254 Pontiac Description

The Anti-Lock Brake System (ABS) relay supplies battery voltage to six valve solenoids. The Electronic Brake Control Module (EBCM) microprocessor applies the grounds needed to activate each solenoid. The low side of each solenoid coil has a feedback circuit to the EBCM microprocessor. When a solenoid is commanded OFF, the feedback voltage is high. When a solenoid is commanded ON, the feedback voltage is low.
