Lexus ES: Freeze Frame Data
FREEZE FRAME DATA
FREEZE FRAME DATA
(a) The absorber control ECU stores system condition information as freeze frame data the moment a DTC is stored. The Freeze Frame Data can be displayed using the Techstream.
(b) Freeze frame data when a DTC is stored.
(1) Freeze frame data is stored the moment a DTC is stored.
(2) When freeze frame data is stored when a DTC is stored, the data is not updated or deleted until DTCs are cleared.
CHECK FREEZE FRAME DATA
(a) Turn the engine switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the engine 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.
