Driver side seatbelt causes airbag warning light


Recommended Posts

After working on my central locking issue and reinstalling the driver's seat, Durametric reports a driver seat belt error code, which triggers the airbag warning light (I think it is is code 45 - don't have it in front of me). Reading various threads including this one, TSB 1/04 6924 Airbag Warning Light Comes On: Fault Codes 45, 46, 48 and 49 -- dated Jul 21, 2004 is referenced. I have verified that my VIN is prior to the manufacturing modification to use the new wiring harness. I've also seen that the driver's side seat belt receptacle is "sticky". I've tried cleaning contacts, etc. but no dice. I've also measured continuity between the ground points and the appropriate pins on the connector to the seatbelt receptacle and they look good. Questions:

  1. Can I remove the seatbelt receptacle without removing the driver's seat?
  2. Do I really need to perform the wiring harness modification or might just replacing the seatbelt receptacle be sufficient? Looks like I would need to get under the passenger seat to get to the airbag module to do so properly.

I removed the driver seat after consulting with my mechanic who suggested that it would be much easier. I put in the new buckle but I still have the same problem (Code 46). With the ignition set to on, and subsequently with the engine running, I cleared the code using Durametric, but it returned when I switched off the ignition and switched it on again. From the workshop manual, I measured the resistance between the buckle pins and got the correct 400 Ohms resistance, so the replacement buckle is good.

2. On the connector that comes from the wiring loom of the car, I've measured the resistance between the grounded pins that go to the belt buckle and the ground point by the alarm control unit and get about 1 Ohm. When I measure the resistance from the brown wires in the same header connector, I get under 1 Ohm. I wouldn't have thought that this difference would be enough to trigger the warning. What do you think?

I determined that the cause of my problem was Durametric 6.5.3.5 not being able to reset codes. The 6.5.3.6 version released on 5/3/17 has fixed this bug. Plugging in the seat belt receptacle to the wiring harness, turning the ignition on and clearing the code did the trick.

thanks very much.  I didn't know that Durametric had an update.  Never see any news about that.

I rarely use it, but have it on a partitioned (via Bootcamp) MacBook Air that I generally take with me on road trips.

I remember updating my Durametric software when I looked at a post on the forum quite a few months ago.

I think I was using 6.5.2, but really don't recall.

I take the Mac so I can reset the airbag light.

I'm current now, uninstalled the older and reinstalled the latest version, and thanks again for the timely heads up.

 

And hello to my Fast Yellow friend as well.  j
