Lexus NX: Freeze Frame Data

FREEZE FRAME DATA

FREEZE FRAME DATA

(a) The absorber control ECU stores the vehicle condition when a DTC is output, and this information can be displayed using the Techstream.

(b) Freeze frame data when a DTC is output.

(1) When a DTC is output, the freeze frame data at the time the DTC is output is stored.

(2) When freeze frame data is stored when a DTC is output, the data is not updated or deleted until DTCs are cleared.

CHECK FREEZE FRAME DATA

(a) Turn the power switch off.

(b) Connect the Techstream to the DLC3.

(c) Turn the power switch on (IG).

(d) Turn the Techstream on.

(e) Enter the following menus: Chassis / Air suspension / Trouble Codes.

Chassis > Air suspension > Trouble Codes

(f) Select a DTC to display the freeze frame data.

(g) Check the freeze frame data for the output DTC.
