This is a 2006 Hyundai Sonata w/ 3.3 engine. 62,000 mi. The air bag warning light on dash comes on and goes off intermittently.

Any ideas of what causes this? What can i check? Is there really a problem?

Had that happen twice on our 07 Sonata. First it went off by itself, second time I checked through some threads here on our board. I found a few people with the same issue. It was recommended to check and secure all the plugs under the drivers seat. I unplugged all the plugs and reseated them. Problem went away and hasn't come back. Barring all that it still may be wise to have any codes read just in case there's a serious problem.

[b]Yes, SRSCM has detected a fault somewhere in the SRS system.

What can i check?
[b]Nothing, will need to visit Hyundai dealer and scan the SRSCM for DTC and proceed from there.

Is there really a problem?
[b]Scan and retrieve the codes, go from there.

thanks for your input. I pulled all the information I could find at hmaservice.com

I think i will try to reseat all the connectors that i can get to for the Restraint system.

I can't even pull codes since the Hyundai specific tester is required.


Question: is there a way to temporarily prevent the fault light from being illuminated? The reason i ask is not because I want to see this getting fixed but that my son needs to do his driving test in this car on Wed. It's my understanding that the car can't be used for a driving test if there are any vehicle fault lights illuminated. Actually I am told it might be even more extensive than that. Since Maryland went to a on the road driving test they said you must have working air conditioning as well. well at least the AC is fine in this car.

Gots to call BS on the working A/C as a safety requirement.. sound like inspector comfort request..

SRS.. as noted before, nothing you going to do except guess,, and waste a bunch of your time.. SRS is constantly checkiing itself for faults, so you know it is ready for popping squibs when needed.

If you really wanted to go to extreme, you could replace squibs with dummy loads.. then SRSCM wont know if igniter is there or not, it just see the load on the circuit and assume all is well. Could unplug themodule, and hope inspector not know to look for SRS light during self test when initail key-on.

i really liked this suggestion. I reseated all connections under both the driver's and passenger's seat, but I still have the Air Bag light lit.

I will take it to Hyundai service since that seems the only way to reset the light and hey maybe there is a real problem here. I also have a recall that also needs to get taken care of on the brake lights.

Question for SBR: in another thread you mention also getting a PCM update. Since the car is in there anyway is that something they will do for free?

If the car falls in the 5/60, tell them the idle fluctuates cold... they dont need code for that concern, that'll get you the new style TPS and PCM upgrade to latest version if not there yet.

Biggest SRS thing we see with the early NF is 1448 for OCS mat defect ($1000 seat bottom replace) and buckle pretension codes for either front buckle exploder.. buckle assembly is just less than $200 each, come in grey or beige.. I got a pile of them here and at home that I need to discharge the exploder before tossing in trash.

I have 1 with a warning light circuit code that wont go away.. back for 3rd attempt. Found previous history on chassis that shows body shop visit numerous times, and previous warning light circuit before I got it.. and appesr to have had wiring harness repair or replace (need to dig deeper and find the truth).

thanks for your input. I think it just passed 62,000 so there may be issues at the dealer over the 5/60.

I remember reading somewhere about the OCS mat. that sounds expensive. Is safety related stuff warranties by Hyundai for over 60,000 mi?

thanks again everyone for your input.

OCS (seat cushion) is customer pay after 5/60.. runs approx $900 for cushion, add labor.


Couple pics of cushion-OCS mat, and last is pic of seat frame minus the cushion
