BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS  ELECTRONICALLY CONTROLLED BRAKE SYSTEM(w/o VSC OFF Switch)  FREEZE FRAME DATA  


FREEZE FRAME DATA/INFORMATION


a.

Using the GTS, check the vehicle condition (ECU, sensor) when the brake system operates or a DTC is output.



CHECK FREEZE FRAME DATA AND INFORMATION WHEN DTC WAS STORED


a.

Freeze Frame Data is stored when a DTC is output.

Once Freeze Frame Data is stored when a DTC is output, it is not updated or cleared until the DTC is cleared.


c.

Check the corresponding freeze frame data and detailed information of the DTC.

i.

Turn the ignition switch off.


ii.

Connect the GTS to the DLC3.


iii.

Turn the ignition switch to ON.


iv.

Turn the GTS on.


v.

Enter the following menus: Chassis / Brake / Trouble Codes.

Chassis > Brake > Trouble Codes
