It’s not really a big deal whether it has it or not but if it does I would like everything in the car to work. I’m pretty hands on and have been working on Lexus for about 10 years all of my own cars. So I am familiar with how they do things. This is my first ls I’ve been a gs boy. Regardless I just find it hard to believe I have 3 out of the 4 things needed for this to work. Can anyone direct me which ecu the wave sensor is wired to? This may help me also I may find a harness open or taped up

 

Then you should have no trouble checking the VIN for a list of options the car came with. That will give you a definitive answer. It's understandable why you you think you may have it. You don't need to take members opinions as fact. A dealer can easily look up the VIN if you don't know how.

 

A used steering wheel is cheaper than an air bag.

 

DRCC either works or it doesn't. If it does, it's great. Have 2017 and works about 80 percent of the time. Taken to the dealer about 5-6 times and has NEVER been resolved. Good old fashion pedal control seems to be the answer!!!
