Anti-Lock Brake System -- Fail-Safe Chart



FAIL-SAFE OPERATION
  1. If there is a problem with sensor signals or brake actuator systems, the skid control ECU will prohibit power supply to the brake actuator and terminate ABS control.
    ABS control is prohibited, but EBD control continues to the extent that it is possible. If EBD control is impossible, the brake warning light comes on to warn the driver (LandCruiser RM000000XHP0JQX.html).
  2. If a system component has any malfunction before control begins, operation is prohibited. If a system component has any malfunction during control, the system will gradually stop operating so as not to trigger a sudden change in vehicle conditions.
    If it is impossible to control the systems, the warning light comes on to inform the driver of termination of control of the systems (LandCruiser RM000000XHP0JQX.html).
