INSPECTION PROCEDURE

1 RECONFIRM DTC

HINT: This code is detected when a problem is determined in the brake actuator assembly.

The solenoid circuit is in the brake actuator assembly.

Therefore, solenoid circuit inspection and solenoid unit inspection cannot be performed. Be sure to check if the DTC code is output before replacing the brake actuator assembly.

(a) Clear the DTCs (See page BC-82).

(b) Turn the ignition switch to the ON position.

(c) Are the same DTCs recorded?
