Note
When replacing the DRS ECU (rear steering control ECU), perform neutral position memorization and motor rotation angle sensor calibration.
If the rear steering link assembly or rear suspension is removed and installed, replaced, or adjusted, after performing actuator calibration value initialization, perform neutral position memorization and motor rotation angle sensor calibration.
PERFORM ACTUATOR CALIBRATION VALUE INITIALIZATION
Note
When actuator calibration value initialization is performed, the actuator is forcibly activated. Therefore, raise the vehicle so that the rear wheels can be turned without any load.
When actuator calibration value initialization is performed, DTCs are also cleared.
If any VGRS system DTCs other than C15C9/76 are stored, actuator calibration value initialization cannot be performed.
Raise the vehicle and position the tires straight ahead.
Turn the power switch off.
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Enter the following menus: Chassis / DRS / Utility / DRS Off-center Correction.
Follow the GTS display and perform actuator calibration value initialization.
PERFORM NEUTRAL POSITION MEMORIZATION AND MOTOR ROTATION ANGLE SENSOR CALIBRATION
Note
When neutral position memorization and motor rotation angle sensor calibration is performed, the actuator is forcibly activated. Therefore, raise the vehicle so that the rear wheels can be turned without any load.
If DTCs other than C1B01/11 and C1B04/14 are stored, neutral position memorization and motor rotation angle sensor calibration cannot be performed.
If any VGRS system DTCs other than C15C9/76 are stored, neutral position memorization and motor rotation angle sensor calibration cannot be performed.
Make sure that the vehicle speed is 4 km/h (2 mph) or less.
After raising the vehicle, position the tires straight ahead and center the steering wheel.
Turn the power switch off.
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Enter the following menus: Chassis / DRS / Utility / DRS Neutral Memorization.
Follow the GTS display and perform neutral position memorization and motor rotation angle sensor calibration.
