2001 Hyundai sonata, airbag light is on, checked under passenger seat and found small modular that has 2 connector's and the bottom of the modular is broken which I can see the circuit board, I unplugged it and nothing changed so I imagined it might be bad, I looked under driver seat and found no modular and there is a wire with a connector that goes no where, help please. thank's
First the airbag system can be dangerous to work on and it is usually best to consult a professional since to accidental inflation of an airbag can cause injury, do not cut any wires and disconnect the battery when working on the system.
When the airbag light is on it disables the airbag system inmost vehicles meaning if there is a collision the airbags will not deploy. Some autoparts stores can check codes which is where to start with the warning light on and modular connected check the airbag trouble codes with this information it will be easier to diagnose the system and the cause of your problem. I hope this helps

You change One spark plug, and One wire at a time. Do you know where your timing belt is? If not, its on either the right or left side of the engine. There is a covor to the timing belt. You take the First plug that is closest to that belt. Then you work your way to the next closest all the way to the last one. Remember, you have to do ONE at a time.

The problem is the seatbelt latch. The wiring right at the latch and the strap are broken. Seems there is not enough slack in these wires to allow much stretch. You may be able to repair it if you can splice these wires back together if not about 160 to 170 for a new one. you can have it put on a machine and if the code leads back to the latch then you know this is the problem.

Often there are 'UNUSED' wire harness connectors in various places on vehicles (i.e., heated seats for example when the vehicle didn't come with them). The best solution is to find out what trouble code exists in the SRSCM (Supplemental Restraint System Control Module). There are over 100 different codes/troubles which can turn on the AirBag light. Take the veh in to a Hyundai dealership to find out what code(s) has/have been stored in the SRSCM -- it simply might be a "History" code, like DSAB (Driver's Side Air Bag) Resistance - High - H. Hyundai Dealerships use two different scanning systems - HighScan and GDS. Once you find out which code, you can go to http://www.hmaservice.com/ and register and access all the info you want about your Sonata. CAUTION: Air Bag systems encorporate explosive components - trust the professionals

There are no campaigns/recalls for the SRS (Supplemental Restraint System - Air Bag). However, there is a Service Bulleting regarding the wiring harness under the seats:
DESCRIPTION:
Motion of the side impact air bag wiring harness and connector may result in illumination of the air bag warning light and one or both diagnostic codes listed below:
This campaign provides a new side impact air bag wiring harness connector mounting procedure.
VEHICLES AFFECTED:
SPECIAL NOTES:
The service procedure to be followed depends on the original wire harness routing under the seats. The required parts are different for each procedure.
If your vehicle doesn't fall within the production range, it's not affected.
I recommend you take the vehicle into a Hyundai Service Department and ask them if your vehicle has had this repair already. If it doesn't apply, pay the diagnostic fee to find out what the problem is. They will give you an estimate of repairs (parts, labor, tax, time-frame, etc.).. Then you'll know what the problem is.
