INSPECTION PROCEDURE

PROCEDURE

1. RECONFIRM DTC
These codes are 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 is output before replacing the brake actuator assembly.
(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.
(b) Turn the ignition switch to the ON position.
(c) Are the same DTCs recorded Reading and Clearing Diagnostic Trouble Codes?
HINT:
- The skid control ECU inspects the solenoid relay circuit when the stop light switch is turned off and the vehicle is running at a speed of 4 mph (6 km/h) or more.
- These DTCs may be recorded due to a malfunction in the connector terminal connection, etc.

NO -- END
YES -- REPLACE BRAKE ACTUATOR ASSEMBLY
