SRS Light won't reset?!?!

[DoubleAIm]

I have a SRS light on the X5 since I got the car and wanted to turn the thing off. Got me a BMW SRS reset tool B-800 model and give me two codes

F0 - Internal Error
50 - Supply Voltage

I have tried clearing them but it doesn't work and have no idea on were to look for the problem? Anyone experience this before??

The SRS light being on tells the driver that the system is not active and will not deploy the airbags as designed in the event of an accident. Since this is a safety issue, I kinda doubt if anyone on this forum would want to take on the liability of instructing you on how to repair the Safety Restraint System, blame the damn Lawyers in our society that just waiting to sue your ass. My advice will be to take it in to the dealer or a shop that can repair the problem and willing to take on the liability.

The age of your X will certainly dictate that it should be on its 2nd battery, if not third by now. If the battery was recently change by you, or by whomever you obtained it from recently and then the code came up you will want to double check the 'safety trip connection' (not sure the terminology of the part) on the negative connection. That is, on the negative connection terminal there is also an additional connection that will act as safety trip to disconnect the connection to the battery in the event of an accident.

As with all battery work you will want to work safety first and ensure that you properly remove and shield both terminals a terminal connections from accidentally creating a circuit or accidental conduction on metal by utilizing something non conductive.

If this connection was compromised in that the wires were loosened when connecting/reconnecting a battery, and then those wires are no longer shielded an now in some way touching either each other or its terminal connection (note not the [-] connection, but its own), then it will throw a code that cannot be cleared until you solve that problem. In my case, I had the airbag light on because this connection was accidentally loosened, the wire rose up in the plastic harness/housing and was touching its terminal. Solved by examining battery connections and said safety terminal. Pushing wire back down in proper place and shielding with proper elec. tape, clearing code.

Let us know if this was the culprit and good luck.

As upallnight mentioned, should it be anything other as in something actually affecting your SRS system you will want to have it professionally looked at for your safety.

Yeah, I got my SRS on recently but I would suspect it's something to do with the driver seat in my case. I had it removed to dye it and that's the time it came on and never went off.
I tried clearing it with GT1 or INPA and it doesn't let me. I will have to investigate. It could be something like seat occupancy sensor for example...

When the you can't clear the light it usually means that the light actually resets the same codes and the same problem right away.

Internal error, kinda says it all for me.

If it was the occupancy sensor, you would get an occupancy sensor code. And I'm pretty sure there isn't an occupancy sensor on the driver's seat...

If you cant clear the code (or it comes back right away) it means the fault is still active...

Maybe I misread your post, but are you saying that you bought the car with the airbag light on?? ---Why not take it back to where you got it?

Don't sit I the seat you are trying to reset.

If you removed your seat and unplugged the seat belt wiring harness while the car was still powered (did you pull the negative battery cable first?)...then that is why your SRS (air bag) light is illuminated.

The SRS (suplemental restraint system) includes not only the air bags...but the seat belts, too. If you disconnect any SRS electrical connector while the car is powered...it will set/record a fault code. Since you have access to a GT-1 & INPA...check for a seat belt fault code...especially the one that you removed. Also check its electrical wiring harness to make sure it's plugged back in correctly.

ALWAY disconnect the negative battery cable before disconnecting ANY SRS connector...and DON'T reconnect the negative battery cable UNTIL you've reconnected the SRS wiring harness. (unless you have a SRS reset tool which makes this warning moot).

Thanks qsilver. Well, my double garage does not allow me to have two cars with full open doors in it. So, I had to remove the seat on the driveway and them move the car back in. Removing the battery before and after I guess wouldn't help since I still hade to drive it without the seat. And I thought with GT1 I could clear it after.
For some reason INPA/GT1 return errors when trying to clear it. I will have to double check the harness. Since all the seat functions work I assume that the connector is properly plugged.

Look closely at the connections around the seat belt receptacle (#13 - the tensioner).
