Airbag light is on. (INPA Screen shots provided)

On Feb 25th 2012 I bought the yellow B800 BMW SRS Airbag Scan & Reset Tool off amazon. It would not clear anything, and gave no meaningful codes. Next I took it to a local shop and was given the same meaningless codes as the B800.

As frustration amassed and time passed I became complacent with the error.

Well today I got INPA up and running and I have meaningful data! Its time to address this issue.














Thank you for any help you can provide.

There are a few different codes there, but they could have been around for ages. The first thing to do is to clear all the codes and then see which, if any, come back so that you know you are chasing a current fault rather than an old or one-off problem. Can't help with the EDIABAS error, I'm afraid.

[Tib]

I get that EDIABAS error when I try to clear the codes

[BladeRunner919]

Oh, that's irritating. Does that happen when you try to clear codes on other modules, or just on the Airbag?

[Tib]

I have no other codes to clear...

[BladeRunner919]

I think you can still select the 'clear codes' function on a module even if there aren't any. Might be worth a try, just to see if the communication works ok on those.

But I suspect you may need to ask on the diagnostics sub-forum about the error.

I've never seen that error before, but I suspect it's not an scanner error. It appears the SRS module is saying "talk to the hand" when issued a code clear command.

You have codes for every component related to the seats. Both sides. Stock seats?

[amancuso]

Error 240 is damning, it cannot be cleared. That means you need a new SRS computer from my harried experience. I bought a used unit that was in a car without airbag deployment that had errors in it, however there was no 240 error in it. Essentially plug n play. Installed new (used) unit in my car, reset the codes and all is well.

Yes stock seats.

Randy, the Error 240 (Internal Error) Is causing the "Talk to the Hand" reaction.

[rf900rkw]

Crap,. I missed that one final code. Yep, the computer is broked.

[Tib]

WELL that's what I thought when I seen the 240 code... The next set of questions.

where is the ECM? hard to get to?

Where do I send it out to get it fixed? (the ecm)

If I buy a used one does it need to be coded?

how to code one?

[amancuso]

Fun times ahead for you!!! The unit is located under/behind the center console. Console removal is a must.



No coding is necessary if you buy used. Ask seller if the car they are from had airbags deployed or if they have read the computer for codes to see if 240 was present, and the return policy.

[Tib]

hope there is a good guide for that console removal... I know I seen one on how to fix the broken glove box to console tabs, but I cant find it now either.

Dissclaimer: (The below statement is compiled information extracted from several sources/threads and forums off the internet and I do not attest to its validity)

The 240 error is caused by bad caps and a resister pac in the ECU. having the unit re-maned will fix it forever. buying a used one will most likely leave you with the same issue down the road. 6577 8386192 was superseded by 6577 6908896 to help resolve this issue and has a much lower failure rate.

I still have not found who remans these units.

it looks like BBA-REMAN repairs these.

BBA Reman believes that re-engineered parts offer a better and considerably cheaper alternative to buying OEM replacement parts. This is because replacement parts will generally retain the same inherent faults that caused them to fail in the first place, whereas re-manufactured parts have these faults re-engineered out of their design. The BBA Reman approach is to take old, failed units (core), process them to return them to their original capabilities, and then test them to ensure quality compliance and reliability. We now offer a product range in excess of 10,000 parts across all makes and most models of cars. And we are so sure of our engineering excellence that we are happy to give all our parts a lifetime warranty.

if anyone else has had one fixed post where please.

still sorting prices and options...

ECS offers the updated one 6577 6908896.

[amancuso]

I contacted a few fixers and they all said they could not repair my 192 unit however, BBA reman was not one of them. Let us know what they say and make sure to tell them your unit works, but has a 240 code, internal error.

I didn't remove the console for changing the module for the same exact error. I have the old module if anyone wants it for studying its problems.

Glovebox out, then work it out by scratching your hands through the side, and looking at your work through the switch cover holes. Have some flexible 1/4" wrench joints. It's possible without console out. You will look like you fought with a cat, but thus it's possible in about 30 mins.

What he said, I tried this but it was very uncomfortable. I ended up using having the console out to clean and vacuum underneath it.

[HeliHover]

I've pulled my consol a few times. I could lend you a hand Tib, but that would require me to drive and you to read my error codes

Mike

you need your DSC read correct?

[HeliHover]

Yes.

I also have an airbag light on too

Interesting. However mine received the error 240 after I plugged in a seat belt tensioner/receptacle from a 2001 Z3 (updated style) onto my 2000. Returning to the old one (with coffee spilled on it), didn't allow clearing of that error. Maybe the difference in tensioner triggered the resistor to blow? Or maybe the module locked itself.

Great now I have to check and see that the srs system does not have any 2001 parts too?

Unlikely, unless you or any the previous owner did it. I'm just saying that there may be other ways to ruin the Airbag module than a resistor failing spontaneously.

I have no idea what was the cause of the 240 code or when it happened.

I 100% agree with you. We have yet to see any definitive facts as to what the code really means, and at this point nothing is off the table.

device failed self test?
communication error?
component failure?
Incorrect component in the system?

I plan to know by the time this tread is resolved.

This turn of events has made one choice easy I will pull the seats console and the belts to verify every component. I don't need to risk 240ing a 2nd ECU

[328 Power 04]

The wire colors on the seat belt receptacle and tensioner differ in each of the different versions, as well as wire count. So identification will be easy.
