Anti-Lock Brake System -- Fail-Safe Chart



FAIL SAFE OPERATION
  1. If there is a problem with sensor signals or the brake actuator system, the skid control ECU will prohibit power supply to the brake actuator and terminate 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 (COROLLA_ZRE142 RM000000XHP0ELX.html).
  2. If an ABS system component malfunctions before ABS control begins, ABS control will be prohibited. If an ABS system component malfunctions during ABS control, the system will gradually stop performing the control so as not to trigger a sudden change in vehicle operation.
    If it is impossible to control the systems, the warning light will come on to inform the driver of system control termination (COROLLA_ZRE142 RM000000XHP0ELX.html).
