Special Service Campaign (SSC) FLD - Certain 2007 Model Year RX400h Vehicles - Engine
Has anyone done this update?
Description
The subject vehicles may be unable to pass certain state emission testing requirements due to incomplete sensing by the required Air Fuel (A/F) monitor. Lexus has developed new engine control software logic to help prevent this condition from occurring.
Any info would be great??

Not sure of the details for your SSC but there was one a few years ago that was just a software bug fix. Hybrids were failing the emissions test even though their emissions were fine and the patch corrected the issue. Many states exempt hybrids from emission testing so this was not a widespread issue. It seemed to pop up when CA started testing hybrids. Did you flunk an emission test?

Thank you for the response smassey321!
Just hope it doesn't affect MPG!
its a Cali car, but its not in Cali anymore. Lexus dealer just wanted to make sure it was done?
Just seeing if it had any ill effect on MPG ....
Thank again!
