GENERAL INFORMATION

OUTLINE OF CHANGES

Due to the addition of an electric parking brake, the troubleshooting has been changed.
The Forward Collision Mitigation (FCM) is controlled by the FCM/LDW/AHB-ECU instead of the ACC/FCM-ECU. For the details of the FCM/LDW/AHB-ECU, refer to GROUP 54A - FCM/LDW/AHB-ECU .
The troubleshooting procedure for the Forward Collision Mitigation (FCM) has been changed as a FCM/LDW/AHB-ECU has been employed.
A steering wheel sensor has been integrated in the column switch assembly.
The wheel speed sensor <rear> has been relocated (Refer to GROUP 35B, Wheel speed sensor removal and installation <REAR> ).
"FCM ON/OFF switch" has been renamed as "FCM and Ultrasonic misacceleration Mitigation System ON/OFF switch."
A brake auto hold function has been added. <Vehicles with electric parking brake>

BRAKE AUTO HOLD FUNCTION <VEHICLES WITH ELECTRIC PARKING BRAKE>

General

When you press the brake auto hold switch while the vehicle is driven or stationary, the system enters the brake auto hold mode, which constant braking force is held hydraulically. In this mode, you can release the brake pedal while you wait for a traffic light or are in a traffic jam

Operation

Status	OFF	ON (stand by)	Active	ON (stand by)
Vehicle status	-	Press the brake auto hold switch while the vehicle is driven or stationary with the seat belt fastened.	Stop the vehicle to wait for a traffic light, and then release the brake pedal. The ASC holds the vehicle stationary hydraulically.^*	Start the vehicle by depressing the accelerator pedal.
Vehicle status
Brake auto hold switch indicator	OFF	ON	ON	ON
Brake auto hold indicator	OFF	OFF	ON	OFF
Stop lamp	OFF	OFF	ON	OFF

note

^*: When any of the conditions is satisfied while the vehicle is held stationary hydraulically, the electric parking brake holds the vehicle instead:
The electric parking brake is activated under any of the conditions below:

Unfasten the seat belt (driver’s side).
Open the door.
Turn the ignition switch to the "OFF" position.
The system detects the movement of the vehicle.
The vehicle is held stationary for ten minutes.
The selector lever is held halfway between any two positions for at least five seconds.
Malfunction of hydraulic unit (ASC-ECU)

When the electric parking brake holds the vehicle, the brake auto hold function will be deactivated. Then the brake auto hold switch indicator, the brake auto hold indicator and the stop lamp will go out.
