Nagging Airbag and restraint warnings I cannot clear

worked on my driver's door the other day, replaced the window. I did start the car with the airbag module not plugged in, and twiddled with the window switch a bunch to ensure it was working.

Now, even after going in and manually erasing all error codes in INPA and also, doing a complete Self-check in DIS and erasing all the error codes related to safety, restraint, seats, etc, I still cannot get the error for "Fault in passenger restraint system affecting airbag, belt tensioner or belt force limiter".

I used INPA first. Seats, pillars, satellites, safety, you name it.

By the time I got to DIS, there were no faults currently present, so it appears everything is plugged in.

but I did still clear

Safety and Information Module, 93DF undervoltage


Any ideas?

I replaced a module under the passenger seat and had to "re-time" all of the modules. After I did that the airbag light went off. Did it through DIS, "service" -> maintenance -> body ->
control units in safety system -> start system time

good luck

I don't think thats your door airbag , After all it does say " belt tensioner or belt force limiter "
maybe you should look into checking or replacing your seat belt tensioner . Maybe it's not
plugged in all the way , or there is actually a problem with it ...

RHummer, I tried what you mentioned and I got to the Service pane, but it seems like nothing is happening, can you check this video out, please?



Paper, check these images, the seatbelt AND Airbag lights are on.

Highlight "satellite" go to bottom and select "test schedule" when you get to the test page click on the green arrow at the bottom right. You will get the test protocol to restart the system time,
select the number 1 square and click the green arrow, Worked for me.

good luck

I saw Test Schedule, was afraid to mess with it, thanks, I'll give it a shot.

dang, there's a ton of stuff hiding in DIS. Useful stuff. I was also impressed with how much stuff is hiding in INPA if you know where to look.

Mein Auto: An old pair of Clarks.
I have the same exact problem.. except mine came spontaneously one night while driving without my seatbelt on. I had not been wearing my seatbelt after driving about 10 unique times over a period of around 300 miles. I always thought that the electrical system thought that since so many miles had been put on the car without ever wearing the drivers seatbelt, that it tripped some sort of safety device. I had to listen to the seatbelt thing dinging and dinging each time, ( dont even ask why I wasnt wearing my seat belt, but I assure you it was a good reason ) but now it doesnt even ding. However, it does show the same lights on the gauge cluster and the notice on the idrive.

Could it be what I said? A safety trip? Like a checks/balance system in the electronics? In other words, a system, where the car thinks that the driver wouldnt possibly drive that many times and put that many miles on the car without a seatbelt on? So it think that there must be a problem with the seatbelt, instead? I've worn my belt ever since and it hasnt gone away.

I would love to solve this problem.

INPA or DIS would be the first or access to someone with the cable and software. Once you scan it will give you a direction to resolve your issue.

Rhummer, thanks a ton for the detailed screen shots and explanations. Unfortunately it did not work for me. I am sure I was doing it right, clicked on square 1, press the right arrow, get an hourglass. once it comes back, prompts you to check all the modules to see if they are re-set. I did, and they all were.

dang it.

In the splash screen for the test it actually has a bunch of documentation describing how the modules need to all agree on time. the only difference is: I never got the error code that they mention that tells you "dude, a module is not in sync with time". (can't remember the code #)

yes, tried #2 for Safety Information Module as well. I think there's a strong possibility I stretched and yanked a terminal out of the airbag module plug. The door panel was hanging on it for a minute or so. Dumb thing to do.

I do have a spare entire plug with wires on my wreck. If I tear off the door cover and check yet AGAIN that I did not leave something unplugged, I could try splicing that airbag module plug, and re-setting everything and see if it helps.

Thing is: all the airbag status polls in INPA say everything is fine.

Re: Nagging Airbag and restraint warnings I cannot clear

Well I had the same fault after adjusting my passenger seat around one night, saw this when I ran diagnostics, I just went and clicked on "Delete fault memory", a few seconds later the airbag light on the dash disappeared as well as the notification in the car's data under Check. Went and sat in the passenger side and the "passenger side airbag off" light went out. So far so good, also deleted a couple other faults the cold weather here in Colorado must've tripped like fuel sensors etc. Now just gotta drive around and see if any of them comes back...

If any safety modules were unplugged they need to be resync before the trouble light can be cleared

Jon745 I did a short test in DIS on all modules and cleared every single error the car had. Also checked things out in INPA in all the safety sections. Waiting to see what Nygel says about syncing the safety module.

In DIS i heard there are some steps to re-sync the time to the module. Or you can use ToolSet32 to resync the time or re-align as they call it

Re: Nagging Airbag and restraint warnings I cannot clear

Well I didn't unplug or replug anything. The fault just came up one night when I decided to move the seat around. Same thing I did, did a self test then cleared each fault after checking out the details. Most of them were caused by the weather conditions here like for example, it threw a DSC code when my tires were slipping due to icy roads a couple weeks ago, It said the battery went undervoltage, and we all know how the cold could kill a battery, I had almost a full tank, and after the temp dropping -20 the dash said I didn't have any gas lol. my 745Li came from el paso, so the I'm blaming the whole climate and altitude change. I've seen around the forum how some owners say that low battery voltage could throw some fluke codes...Imma just wait and see if they pop up again.

Nygel, if you look at the conversation with myself and RHummer. That is what we were doing. Since it did not work, I have to think: OK you idiot, you took your door panel off, you unplugged a bunch of stuff, you even let a plug hang with some weight on it for awhile, you need to go back in and recheck all that stuff. There was even one drive home recently where my arm rest window buttons on the driver door did not work at all. Then next day, they are fine. Makes me think something might be a bit loose.

Have not done so because of the holidays and tons of my own Honey Dos that are more important, like swapping in newer rear trunk lid lifting mechanisms into my aging 760 with the new, somewhat heavy spoiler. I got all the parts off my wrecked 760 parts car.

Nygel, maybe I was not clear. I tried that tab. RHummer walked me through it. I even made a movie for future generations so you can see how it goes. It did not work. Probably because I F'd my door panel or airbag plugs up.

meanwhile, Jon 745: I bought a wreck... for spare parts. I did not wreck mine. Click on my name and look at my old posts for the epic story of the 50K mile motor I traded my old 135K motor for, to keep the car fresh.

YESSSSSS!!!!!!! Had a great conversation with Jeremy at oetuning.com about something totally unrelated. He mentioned there are what he calls "Shadow Faults" that are more like a fault-history list that doesn't get cleared when you specifically clear a module's faults. They get stored in the vehicle's archive. I guess this airbag fault was important enough that it felt it needed to be heard, no matter what.

Here's how to get rid of it:

INPA
E65 (F4)
Choose: Functional Jobs
F4, Error Mem
F1 Read Error Mem.

This is the big difference: make SURE the top of the window says "Scope: All Control Modules". This will clear all errors for all control modules.

F2 clear error memory.

to ensure a good take of this, exit and shut the car off, remove the key and don't start again for at least 5 minutes. Let the car go to sleep.

My airbag light is now gone.
