Hello I have a 2007 IS250 that I've owned for around 4 years and has around 134,000 miles on it. I'm on a trip for work so my mother has been driving my car for the past couple of weeks. She called me a couple of days ago saying that almost all the lights on the dashboard lit up.
Check Engine Light
VSC Light
AFS Light
Traction Control Light
All these lights are on the dash right now. I told her to go to an auto parts store to do a free engine light check to see what codes they get.
They gave her these four codes:
B1660
C1201
P0441
P0455

I won't be able to take it back to a shop until I'm back and I wanted to know what these codes meant and if I should have her stop driving the car immediately. She says she notices nothing different in the way the car drives or starts. Thanks!

 

I would have her tighten the gas cap, and then have the auto parts store clear the codes. P0441 and P0455 are both codes associated with the evaporative emissions system, usually a loose gas cap.

B1660 is for the passenger airbag; Did you recently have the passenger airbag replaced due to the recall? If so, perhaps this code won't come back once it has been cleared.

Don't worry about C1201 yet. It will probably go away when the other problems are fixed. (The ECU disables traction control when the check engine light is on)

 

Thanks I will let her know! I don't remember if the dealer replaced the airbag when I took it in for some of the recalls it had. It's been over a year since. I will check on that. So the other lights should go away after fixing those? Such as the VSC and check engine? Thank you so much for your help

 

like the previous user said, open and retighten the gas cap, clear codes, have it rescanned. if they come back up on the rescan the gas cap is obviously not the issue. you can google the car make and year and code numbers to get a description of whats wrong. take it to a mechanic and ask him whats wrong then compare to your research (if you dont trust the mechanic) or just tell him what you found (if you trust him)

no way the airbag was done a year ago, its a more recent recall. you should get a letter in the mail when your local dealer is taking care of it. or call your lexus and ask
