Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

SOURCE: Air bag light won't go off

It likely is a bad passenger air bag. Did you try switching it back to off on the switch,and unhooking the battery for 5 minutes.

The only thing I can think of that would explain your problem is a faulty ignition switch.

SOURCE: 2001 GMC SIERRA . ABS LIGHT STAYS ON

Wheel speed sensors misadjusted, damaged , or metal shavings and other debree, since they are magnetic can give false readings from one of the wheel circuits. Over sized tires can give of false speed readings as well. there are many other causes including bad relay, control module, e.t.c. It is best to have the proper scan tool to diagnose an ABS problem

SOURCE: 2006 Ford F150 ABS light and Air bag light stays

The usual problem causing the AIR BAG light is a poor connection on the YELLOW CONNECTOR under the passenger seat.

Push it firmly together and that should cure the Air Bag Light

SOURCE: 2003 VW Jetta air bag light and ABS light stays on

no it wont. in order for the air bag light to go off you must get a VW air bag resetter. they sell for about 45 bucks. it will reset the light and crash data. since your airbag light is on the airbags are locked up. once reset they will work again. anymore questions give me an email... andrewlangner@yahoo.com

Air bag light came on sudenly on my prius 2009, what could be the problem?


The air bag light is only part of the srs system
You have seat belts,seat sensors,air bags,all sorts
of sensors,so it could be any thing
In most cases you would need factory service manuals,
if you were to diagnose yourself, as abs codes & trouble
charts are not an internet source of info, as with generic
obd codes
You start at a repair shop with professional software to get the
codes,then they have to go into a data base to find trouble
charts to follow.

My 96 blazer was running fine then battery light came on and abs light and air bag lights came on and then engine started missing.


Blazers aren't necessarily known for bad ignition switches (which it sounds like), but I would suggest a battery problem ( known more for this). Check the battery connections, especially the positive post. Make sure the connections are tight and no corrosion. If the battery checks out good then I'd suspect the ignition switch failing. The ABS and AIR BAG lights will come on when the battery gets low.

Heater not blowing,air bag light on,abs light on


These faults wont be related.

No hot air will be the thermostat very common on these cars and not an nice job to do either.

Abs light will most likely be a sensor to the brakes they have 4, you can clean these up and it sometimes resets the light, but not always, these are attached to the callipers and easy to remove.

Air bag lights are very random, you will have to get it turned off by a garage, they just come on for no reason it seems. you can check the air bag sensors but to be honest it's not worth the hassle as like I say they just randomly come on.

Hope this helps

Air bag light giving a 37 code and abs light has been on for two years


As for the ABS light you probably have broken wires at the wheel hub. I just had mine repaired very little cost if you have the right mechanic that knows what they are doing they should have an ABS scanner to pin point the break . this is an ongoing problem with ABS systems.
