Toyota Corolla Cross: ABS Solenoid Control Module Actuator Stuck On (C143A7E,C143A7F,C143D49,C14DA14)

DESCRIPTION

The ABS solenoid relay is built into the skid control ECU in the brake actuator assembly. The ABS solenoid relay supplies power to each solenoid.

The skid control ECU (brake actuator assembly) detects an ABS solenoid relay malfunction by performing a self check and relay operation check.

DTC No.
