  1. FAIL-SAFE OPERATION


    • If there is a problem with sensor signals or actuator systems, the skid control ECU prohibits power supply to the brake actuator assembly and terminates ABS control.

      ABS control will be prohibited, but EBD control will continue to the extent that EBD control is possible. If EBD control is impossible, the brake warning light will come on to warn the driver.

    • If an ABS system component malfunctions before ABS control begins, ABS control will be prohibited. If a system component malfunctions during ABS control, the system will gradually stop performing control so as not to trigger a sudden change in vehicle operation.

      If it is impossible for control to continue, the warning light comes on to inform the driver of system control termination.
