DESCRIPTION
Depending on the malfunction, the skid control ECU (brake actuator assembly) prohibits operation of the vehicle stability control system to protect components and prevent incorrect operation when DTCs are stored.
If the switching solenoid is disabled due to prohibition of the vehicle stability control system, the response of the brake pedal changes and braking performance is reduced.
CAUTION / NOTICE / HINT
NOTICE:
When replacing the skid control ECU (brake actuator assembly), perform system variant learning.
