Failsafe List

  1. Fail safe operation
    NOTE:
    • If there is a malfunction in the sensor signal or the actuator system, the skid control ECM prohibits the power supply to the brake actuator assembly.
    • In response to the signal received from the skid control ECM, the brake actuator turns the solenoid off. Under this condition, the vehicle operates in the same way as those vehicles without ABS, TRC, and Vehicle stability control systems.
    • The EBD control continues to function in a range where the control is possible, although ABS control is prohibited. When the EBD control becomes impossible, the brake warning light illuminates and the driver is warned of the condition.
    • When a malfunction occurs in the Vehicle stability control system components before the Vehicle stability control takes place, the Vehicle stability control will be prohibited. When a malfunction occurs in the system components while the Vehicle stability control is active, the system will be disabled.
    • When its steady control becomes impossible, the warning light illuminates and the driver is warned of the cancellation of system control. (Refer to DTC C1231 STEERING ANGLE SENSOR MALFUNCTION  )
