DESCRIPTION The skid control ECU (brake booster with master cylinder assembly) receives signals from the yaw rate and acceleration sensor (airbag ECU assembly) via CAN communication. The airbag ECU assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition using 2 cir
DESCRIPTION This DTC is stored if internal or external brake fluid leaks are detected due to improper sealing in the brake actuator (brake booster with master cylinder assembly) or brake booster pump assembly. Internal leaks are suspected if the pump motor operates frequently without braking. DTC
