VARIABLE GEAR RATIO STEERING SYSTEM FREEZE FRAME DATA

Tech Tips

The VGRS system stores data when a trouble code is stored which can be viewed using the GTS.


  1. FREEZE FRAME DATA OF VGRS ECU (FRONT STEERING CONTROL ECU)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Chassis / VGRS / Trouble Codes.


      Chassis > VGRS > Trouble Codes

    5. According to the display on the GTS, select the trouble code data display with Freeze Frame Data.
