Lexus ES: Freeze Frame Data
FREEZE FRAME DATA
DESCRIPTION
(a) Whenever a front camera system DTC is stored, the forward recognition camera stores the current vehicle state (ECU and sensor information) as Freeze Frame Data.
CHECK FREEZE FRAME DATA
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Chassis / Front Recognition Camera / Trouble Codes.
Chassis > Front Recognition Camera > Trouble Codes(e) According to the display on the Techstream, select a DTC with freeze frame data.
(f) Read the freeze frame data recorded when the DTC was stored.
