PROCEDURE
1. |
RECONFIRM DTC |
HINT:
These codes are detected when a problem is determined in the skid control ECU (brake actuator assembly).
The solenoid circuits are in the skid control ECU (brake actuator assembly).
Therefore, solenoid circuit inspection and solenoid unit inspection cannot be performed. Be sure to check if any DTCs are output before replacing the skid control ECU (brake actuator assembly).
(a) Clear the DTCs.
