Toyota Corolla Cross: Brake Switch "A" Circuit Open (P057113)
DESCRIPTION
The skid control ECU (brake actuator assembly) receives stop light switch assembly signals and uses them to determine whether or not the brakes are applied.
The skid control ECU (brake actuator assembly) has a detection circuit that it uses to detect an open in the stop light input line.
If the skid control ECU (brake actuator assembly) detects an open in this circuit, it will store this DTC.
