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?
Result
NOTICE: When replacing the brake actuator assembly, perform zero point calibration (See page BC-70).
REPLACE BRAKE ACTUATOR ASSEMBLY
Removal
NOTICE:
Before removing the tire pressure warning ECU, read the
registered transmitter IDs of all wheels and write them
down to use for re-registration of transmitter IDs (See
page TW-20).
