[Solved] Corolla 2012 airbag light issue

Hi Scotty,

 
I'm writing you from Romania and I'm watching all your videos every night (as the time you're uploading the videos, is already night in Romania :)))
 
I have a 2012 Toyota Corolla, 1.6 vvti gasoline, standard transmission and brought this last year from Toyota dealership for a really good price, about 5500USD. The car was 233000 km, now is 241000 km and works perfectly. However, I have one minor issue that is driving me crazy: sometimes, the passenger airbag light is displayed. I took it to a mechanic and he erased the error, but guess what, it came again. I made some research and found this is related to the plastic yellow jack located under passenger seat. Used a cable tie to tight the jack and worked perfectly for months, but now from time to time the light is displayed again. 
 
Any idea about this, is there any solution that may fix this permanently? I'm thinking that an imperfect contact might trigger the error. I saw this is not happening at all when the passenger seatbelt is on. Can I use some WD40 or contact cleaner to spray inside the jack?
 
Regards

Hi Yaser, Scotty,

 

Managed to solve the issue by myself. Followed your advice to change the mechanic and took it to other "toyota dedicated and recommended" service but it looks like I just found other idiots. Probably they did not made any diagnosis, just charged me for nothing.

Then I ordered an Autel Ap200 to make sure the diagnoze is correct. Found that my car has the error B1660, related with the passenger security/airbag panel. Opened the panel, made sure the connection is tight and the airbag on light of that panel start to work again. I never notice that the light never worked before. 

No issue encountered since. Cheers!

First of all, change your mechanic. The light you see is related to the weight sensor on the passenger and is on when it does not detect the passenger. If you use the seat belt, it won’t come on as you see. Your car is perfectly fine.

Thanks Yaser! Good point, it might be related with the weight sensor. But the idea is that I've tested with the seatbelt on, but with no passenger. Usually, no one uses the right seat. Probably, using the seat belt is skipping a computer check and that's why the light stays off.

You’re welcome. Yes, the seat belt tells the computer not to count on the weight sensor.
