DTC C143A-7E: ABS Solenoid Control Module Actuator Stuck On; DTC C143A-7F: ABS Solenoid Control Module Actuator Stuck Off [09/2018 - 10/2023]: Description
These DTCs are stored when a problem is identified in the skid control ECU (brake actuator assembly).
The ABS solenoid relay is housed in the skid control ECU in the brake actuator assembly.
The ABS solenoid relay supplies power to the ABS solenoid and TRAC solenoid.
The solenoid relay is turned on 1.5 seconds after the engine switch is turned on (IG), and is turned off if an open or short in the solenoid is detected by self diagnosis performed when the vehicle is starting off.
