"Passenger Airbag Off" Light always on

[IQtek]

Hi, I just did TSB036-07 on my 07 I4 for the sluggish problem. It turns out very good. Now I got another problem right after that fix, the "Passenger Airbag Off" light is always on even with an adult (over 150 lb) sitting there. I suspect they touched some wires during the TSB service. I will certainly take it back to the dealer and report it back to you. Searching the forum, I saw one reported that the ECU has to be replaced to fix it. Any other hints? Thanks.

The dealer did not touch some wires when performing the TSB.

I will not offer hints to an inexperienced technician/person when it comes to dealing with the airbag system.

Bring it to the dealer.

It's possible that the battery didn't hold a complete charge during the reflashing (reprogramming). That can cause damage. Don't mess with anything, that's what the warranty is for.

hey what TSB did you get done? what that for the hesitation in the transmission?

I doubt wires were crossed. There is a recalibration function in the factory scan tool they can do for you.

I think it is TSB036-07 but in Canada it is called TSB2650/EM6015. After the reprogramming, the engine is felt very strong. You can still have a little bit of hesitation but good enough if not picky.

In terms of the airbig off light, it is back to normal after 2~3 days before I see the dealer. I am not sure it needs time to initialize after the programming or what.
