VSC(VDC) Centering Mode
CAUTION:
- When the skid control computer (brake actuator ASSY) has been replaced, make sure to perform VDC sensor midpoint setting.
- Make sure to perform [VSC(VDC) Centering Mode] on a level surface (grade of 1% or less). While centering, do not shake the vehicle or open/close a door.
NOTE: When performing [VSC(VDC) Centering Mode], make sure to set zero point of yaw rate sensor & G sensor (brake actuator ASSY is integrated) and steering sensor.
1. Turn the ignition switch to OFF.
2. Shift into neutral and apply the parking brake.
3. Connect the SSM4 to the DLC3.
4. Turn the ignition switch to ON.
5. Set the steering wheel in a straight position.
6. On the SSM4 screen, select [Brake Control System]→[Work Support]→[VSC(VDC) Centering Mode].
7. Following the SSM4 screen, perform [VSC(VDC) Centering Mode].
Changing modes
- When it is necessary to temporarily stop the control while operating the vehicle on a device such as free rollers, enter into the check mode. While in the check mode, DTCs listed in the list may be stored.
- If any DTCs are stored, clear the DTCs using SSM4. After turning IG OFF→ON, the conditions are normal if speed sensor related DTCs are not stored.
