FREEZE FRAME DATA

FREEZE FRAME DATA

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

CHECK FREEZE FRAME DATA WHEN DTC WAS STORED

HINT:

  • 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.

(a) Turn the ignition switch off.

(b) Connect the GTS to the DLC3 and turn the ignition switch to ON.

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

Chassis > Brake/EPB > Trouble Codes

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