Jeep Help!

****WARNING* - I KNOW LITTLE ABOUT CARS ****

Hey guys, -I have a 2006 Grand Jeep Cherokee Laredo, and a few weeks ago the airbag light showed up on dash. I reset the battery and checked fuses and it will come back on when I power the vechical up. I went to auto zone to try and check codes, but nothing came back. However just recently my wife and I realized that when she doesn't buckle up, the annoying *ding* *ding* doesn't happen any more. Its almost like the seat is not recognize she is there, or buckling it in. I tried to put more weight in the seat (ie.. me) and nothing. I contacted the dealer and told them say thing, and they said its going to be a $115 fee to just check the car out. Does anybody have experience with this, or have some ideas. We are a bit strapped for cash right now, but I would hate to skimp out on safety to save a few bucks.

Thanks,

It sounds like the buckle is bad-the one that has the button to release the belt.
Theres a sensor and wiring in there that goes bad,pretty common on a lot of vehicles.
Also if the airbag light is on there could be a problem with the pre tensioner.Thats the belt part that is mounted to the b pillar-by the door

Try a scrapyard and see how much they want for the belts and buckles.

Take it to auto zone and try reading the codes again. It you get a code you can search for it on the Internet. or, just try searching for the key words with your problem and model of Jeep. I've had good luck diagnosing and fixing problems on my old Cherokee by searching the web. Jeep owners are pretty good at documenting how they fix similar prelims.

Some scanners can not acess the airbag control module only the pcm.
If you get a code it would be a b code-for body.

See if this can give you a hand ;)

Great link, i'll take it over to autozone again and try to get them to read the codes. I'll post an update.

Does the buckle work OK? Get a flashlight and look inside it real good for foreign objects. My wife had a buckle quit working, turned out she'd lost an earring and it fell inside the damn buckle. That thing was a BITCH to get out too.

I never thought about FO being in the devices its self. Great tips. I've never heard of jeepforum until just today on this post. I'll start exploring...

Besides the buckle look under the seat itself. A lot of new cars have weight sensors actually in the seat, for controlling airbags and the no seat belt dinging.

Simple fix and no autozone will probably not be able to read the code. You have a sensor in the buckle that tells the SRS computer that you have your belt on. The sensor has gone bad, and most likely you need a new buckle with the new sensor in it.

ETA: Just checked my aftermarket sources and you need to get the sensor from the dealer.

That is a pad in the seat itself under the cloth and on top of the foam. In the drivers seat it dosen't matter. Car assumes that if it is running then someone is there.

I would check to see if you have any recalls. You might luck out and it could be covered in a recall.

When you initially turn the key to on, see if the bag light flashes. That's the code.

For example, 3 flashes, a pause, and 4 flashes = 34.

Post that here.

Considering that airbag codes are going to be along the lines of B1203 and B1B0A and things like that, it isn't going to flash.

My Taurus will flash them. I'm not talking about the advanced codes, but in my case it was a pulled wire to the pretensioner.

A lot of that depends on year and make. And also what system. Scrolling through the airbag codes on a Jeep of that year shows that there is not a single two digit code among them. And every single code has letters in them as well.

ETA: An 06 Taurus has only 4 digit codes as well, though only 1 letter per code.

I didn't think you had flash codes in post '95 vehicles?Since they have obd 2.
Each manufacturer is different I guess.

Mine is a 2000, only the SRS system flashes em.

Flash codes typically went out of style when the vehicle went to OBDII but I am not intimate familiar with all makes and models. I know for a while Dodge was giving actual codes in the digital odometer display for a key one key off key on key off key on.

Now that you mention it I do remember that when I worked for Dodge.It only lasted for like 2 years.

Thanks,
If you still had the "ding ding" seatbelt sound, I'd say look at the clock spring in the steering wheel. Jeeps, specifically Wranglers, are famous for the airbag light comming on because of the clock spring. But you typically loose one or more gauges as well. A tap or two on the horn usually takes care of it, for a while. Hell I don't even have airbags, and I've had this problem....

^^most likely the issue, but check the easy stuff before you start throwing money at it. Fuses, the plug/connector under the seat, debris in the buckle, etc. (all of which has already been mentioned)

www.colorado4x4.org (http://www.colorado4x4.org) is a great resource as well. Digger would be the man to ask; he's an ASE master tech, and has forgot more about Jeeps than most folks will ever know. And most of the people are local and could point you to someone trustworthy to look at it if needed.

Pretty sure that stopped in early 1996 for Jeeps. I had a 1996 Cherokee that would still work with the key on off on off on method, my 1998 won't.
Good luck!

My 99 TJ does the on/off/on/off code display.

Great tip, i'll check out the dealer for a buckle and sensor!
