Lexus ES: Freeze Frame Data

FREEZE FRAME DATA

FREEZE FRAME DATA/INFORMATION

(a) Using the Techstream, 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.

(b) 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.

(1) Turn the engine switch off.

(2) Connect the Techstream to the DLC3.

(3) Turn the engine switch on (IG).

(4) Turn the Techstream on.

(5) Enter the following menus: Chassis / Brake/EPB / Trouble Codes.

Chassis > Brake/EPB > Trouble Codes

(6) Select a DTC to display the Freeze Frame Data.

(7) Check the Freeze Frame Data for the output DTC.
