Anti-Lock Brake System (For Sedan) -- Fail-Safe Chart



FAIL-SAFE OPERATION
  1. 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.
    The ABS control will be prohibited, but EBD control will continue as much as possible. If EBD control is impossible, the brake warning light will come on to warn the driver (YARIS_NCP93 RM000000XHP0BBX.html).
  2. If system components have any malfunctions before starting control, immediately stop the operation. If system components have any malfunctions during control, gradually stop the control 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 the systems (YARIS_NCP93 RM000000XHP0BBX.html).
HINT:
  1. If the ABS system malfunctions, the brake system operates normally without the ABS system.
  2. If the brake booster encounters a malfunction, brake performance is gradually lost and ABS control is prohibited.
