B800 SRS airbag tool is not resetting accidental battery on. Getting codes?

While fixing my passenger side window regulator, I reconnected the battery to test the window.
Airbag light instantly went on, and I just shook my head.

I ordered the B800 China SRS tool, hooked it to my OD2 port, and it doesn't reset the light.
(2001 E39 doesn't have the 20 pin round under the hood. You use ODB2 port)
I reopened the door panel, and made sure the airbag power connector was securely fastened. It was.

So, either the SRS tool is bad, or there somehow is a real problem created.

I read the codes it gave.
Codes are given in pairs.
First number is the table lookup number.
Second is the code.

The numbers I get are:
40
11
F0
06

Table 40, code 11. ("Supply voltage")
There is no table F0 or FD, so I can't look up the second error code of 06

Any ideas what I should do?
Will a car pass inspection with an airbag light?

when I had a srs light, I found I had to reset each code separately, with my B800 tool, not all at once.. I don't remember how they we all shown at once... but anyways, I found away to do them separately. Mine was tripped accidently when working on some other part of the car... I never touched any of the parts inside the car itself to set off the srs light. Not sure if this helps at all. it was my only SRS light experience.

How do you reset one at a time?
I either can chose read codes (FA) or clear codes (CA)

You scroll to CA, and then press ENTER.
It doesn't reset anything.

I have found that when using my B800, I had to invoke the CA option several times. From my experience, it's far more reliable when you have the round connector in the engine bay.

I wish I could remember, but it turned out when I did separately, they cleared... but as a group I could not do a reset.. sorry, can't explain it... I was really pissed when I could not reset mine, so it was by accident and persistence.

I had a guy with the DIS setup try to reset the SRS and it came back on.
The error code said something about resistance or voltage.
I was so damn careful and delicate, but I must have somehow damaged the airbag when removing it. Unbelievable.
Maybe the wire got damaged, not the airbag.
If the wire on the airbag was damaged, I can get a replacement airbag.
But, if the wire on the car was damaged, I think I'm screwed.

bump.

EconoBox: any fix for this? I am having the exact same problems-- only difference is it was the driver's side window regulator. The B800 is not clearing the faults and am getting the same code readings as you.

Nope, my airbag light is still on.
I took it to a dealer who tried to reset it with his INPA laptop or whatever, and it would not turn off.
The most bizarre thing is the light went on EXACTLY when I turned the key, so I know this is the cause.
Can turning the key on actually damage the air bag module?

Hey, guys I thought I'd chime in here. This is going to sound very weird, but it worked for me and hell its probably worth a try for you.

Take out every fuse in your glove box.

Every F$%^#$% one.

Disconnect your battery, put the leads together.

Do some kind of lucky thing, Pray, Dance, Drink, Smoke, whatever you need to do.

Put all your fuses back in ( might be good to replace some of the older ones if you have an early e39 like mine with the open fuses. You can also get resetable circuit breakers that fit into the fuse space as well.

Reconnect the battery. Then turn the ignition back on, and from under the hood ( don't connect it to the OBD port ) try and reset.


Worked for me, after 2 weeks of ****ing with it. Even tried DIS and other software nothing would work. I think there was a module creating an error on the bus and nothing would properly communicate. One post I found said that it could be caused from reseting your service light paper clip style but I have no knowledge if thats true.

Good luck.
