Default 2004 Sedona Air Bag Light On

I found a thread here regarding this problem but it's rather old so I'll post a new thread instead of adding to that one in case anyone out there my have a similar problem.

Here's my sequence of events.

I replaced a battery and as soon as the new battery was connected, the air bag light came on. That really didn't make any sense as why that would trigger the air bag light. I had to go to the dealer for a $100 diagnosis that found broken wires in the driver's seat belt buckle. Apparently from what I've researched, this seems to be a common problem with the 2004 Sedona.

Anyway, the service advisor at the dealer quoted $200 to replace the buckle but said that if I was good with a soldering iron I might be able to repair it (they weren't allowed to do that), and the light should go out after a number of ignition cycles although the code would remain in the computer. (I found out later that wasn't good advice, or even accurate.) The service advisor also said that the code was probably in the computer although the air bag light wasn't previously on and that the loss of power by disconnecting the battery probably triggered the light when power was restored. In the absense of any other explanation, I have to assume that one is accurate.

The broken wires were clearly visible very close to the buckle and it was very easy to remove the buckle assembly from the vehicle. So I took it to my work bench and cracked open (carefully) the plastic buckle housing and easily soldered the wires, put it back together but the light stayed on. It wouldn't go out even after a couple of weeks. A mechanic friend (who doesn't have a code reader) suggested I try disconnecting the battery for a while to see if that would erase the code. I left the battery disconnected overnight and it didn't help.

I went back to the dealer to have the code erased and this time was told (by the mechanic, not the service advisor) that they wouldn't do that because the air bag system probably still wouldn't work after soldering the wires because adding the solder to the wires changes the resistance of the wires which the system measures. So there appears to be no choice but to go back to the dealer again to have the buckle assembly replaced and clear the code if I want the air bag system working.

If there are any mechanics familiar with air bag systems reading this, I'd appreciate if you could confirm if this was a correct explanation (just peace of mind!)

(To top it off, my safety inspection was due in the middle of all this. Fortunately the air bag light being on didn't fail the inspection as the inspection is concerned only with road safety, not passenger safety!)

I bought an '02 that had the bag light on. I took it to a friend's shop and he said his scanner couldn't communicate with my van. It should have been able to, it just couldn't.

I discovered the fuse for the SRS system that's located in the driver's kick panel had blown. I replaced it and his scanner was THEN able to talk to my van. Turned out, bad module as well as the driver buckle. The buckle is easy to see the busted wires on but the module is another story. It's not really a booger of a job, it's just buried under TOO much stuff.

I replaced the module and buckle with ones from my parts van and after starting and running for a few minutes the SRS light went away. I didn't have to reset mine at the dealer. I don't know this but I can see how maybe the dealer (knowing full well that the buckle is likely the problem) just looked at it and, upon seeing it was indeed broken, came to a conclusion without even hooking it up. Check your fuse and if it's fried replace it and hope it goes out.

I can't say whether the resistance thing is true or if it's just a way for the dealer to sell another part but if the SRS system has to get a signal from a sensor and THEN back it up with a signal from a belt (to ensure that the bag truly needs to be deployed) then it's possible that it is the case. The belt would measure different resistance when stressed. You should be able to check a belt with a meter to see if resistance does change when the belt is pulled outward (as in a collision). There are 4 wires to the buckle (right?) so it does seem to indicate that the buckle is able to tell the van more than "the belt is buckled". I don't have a schematic so I can't say what each individual wires is for.

The bad buckle from my van failed because the wire is not mounted to anything (it just dangles from the bottom of the buckle casing) so when you buckle up you move the buckle around, bending the wires at the base of the buckle back and forth. Doesn't take long for a thin piece of metal to fray and break when subjected to those conditions. The replacement buckle came from an '03 and it had a black zip-tie holding the wires to the buckle shaft, just under the buckle case. This keeps it from being sheared of by the buckle case. I don't know if this was a home fix or an update on a subsequent model but it's a good idea to do this on your buckles if they aren't zipped.

I had the same problem, and fixed it!

I located a broken wire right at the seat belt clicker part, where it bends. After unplugging it, I removed it from the seat (one screw to hold the plastic seat cover on, one large bolt) and very very carefully cracked open the seat belt receptacle (breaking some of the tabs - be very careful). From there, I use an appropriate "butt connector" with heat-shrink and so on, and checked it with a multimeter. After re-assembly, I tried removing the main fuse, the "memory" fuse, the "airbag" fuses, etc... No luck. A local shop cleared the code for me, as the normal code readers won't do that.

It's thanks to this post that I was able to get a do-it-myself fix.

Jon9876, glad it helped you. Didn't work out so well for me. After being told by the dealer that I'd still have to replace the buckle ($200) I didn't bother with it until a month or two ago and then we decided maybe we should give in and have the dealer replace it so we'd get our airbag system working again. I had the part installed and as I drove out of the dealer, I noticed the light back on again so turned around and went back. They took the van in again and hooked it up to the diagnostics and came back and told me that they couldn't get any reading out of the it and that the airbag system's computer appeared to be fried! A new computer would cost about $1,500. So I wasted the $200 replacing the buckle and still no air bags and that's the way it will stay now.
