Failsafe List
- Fail safe operationNOTE:
- 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 )
ABS, EBD, and BA systems
ABS, EBD AND BA SYSTEMSItem Operation ABS system malfunction ABS, BA, TRC, and Vehicle stability control are prohibited. BA system malfunction ABS, BA, TRC, and Vehicle stability control are prohibited. EBD system malfunction ABS, EBD, BA, TRC, and Vehicle stability control are prohibited. TRC and Vehicle stability control system
TRC AND VEHICLE STABILITY CONTROL SYSTEMItem Operation Malfunction of engine control system (TRC and Vehicle stability control system) Before control takes place: Disables the control. Control ON: Control with brake only Malfunction of automatic transmission control system (TRC and Vehicle stability control system) Disables the control. Malfunction of brake control system (Vehicle stability control system) Disables the control. Brake control system malfunction (TRC system) Before control takes place: Disables the control. Control ON: The control is disabled.
