The solenoid circuit is in the master cylinder solenoid.

Therefore, solenoid circuit inspection and solenoid unit inspection cannot be performed. Be sure to check if the DTCs are output before replacing the master cylinder solenoid.

(a) Clear the DTC Vehicle Stability Control System (for Hydraulic Brake Booster).

(b) Check if the same DTCs are detected.
