I know the way to "shut off" the SRS light, using the key, turning the car to on and off without starting rapidly, and it didn't work. Where are the sensors that are known to rot in the bumper? Also, how would I check to see if the airbag is actually there(besides crashing into something, I'd like to avoid that, lol). It seems to me that the car was in a wreck, as I noticed today that there's two layers of color on the car; There's what looks to me like sandstone grey on my front driver's side fender, under the blue and clear coats. There's also a lighter blue with clearcoat on it, underneath the top coats of blue and clear. I'm thinking I'm missing air bags and/or sensors, so how do I confirm that, without going to the stealership?

Impact sensors are in the fenders, they have red wiring loom going to them just like everything else airbag related.

Not sure but I think the airbag just tears through the steering wheel when it goes off and is a whole assembly? So I think you would know if you didn't have one... I really don't know though someone else is gonna have to tackle this :p . If you really need to check just disconnect the battery and leave it for a few minutes, then take the four screws out from behind the airbag.

Turning the key on and off rapidly is NOT guaranteed to reset the SRS codes. I tried this several times on mine and it never worked. I finally broke down and took it to a dealer to have them reset it and it never came back on.

As much as I hate to say it, I'd recommend taking the car to the dealer and getting them to read the codes so that you know what's actually tripping it so you know what to go about replacing to fix it.

There's a very good chance that the light might have gotten tripped if you've ever had a dead battery as the SRS computer will trip a code if it tries to run it's self test anytime when the voltage is to low.

and on top of that, if your srs light is on, your bag will not deploy. so even if you do decide to run into something to see if it is there it wont go off.

chances are you have a bad clock spring and not crush/g sensors.
that is 100% false information right there.

SRS light does NOT mean airbag malfunction nor does it mean they will not operate. Trust me. It just means that there is a code that it detected at one point.

Sure its possible they won't if something is ACTUALLY wrong, but the vast majority of the time nothing is actually in malfunctioning.

Check your reverse light switch fuse and see if its blown out. If it is, try removing the fuse and doing the key turn on/off 15 times.

Sometimes when your reverse light switch burns out and blows your fuse your SRS light comes on as well. Easy fix to try.

So, looks like it's off to a stealership... :( Can I take my car to a Dodge dealership that I trust, or doesit have to be a Mitsu one?

To read SRS codes off of your 91 ES- a scan tool would have to be hooked up to Mitsu's proprietary OBDI data link connector. I would highly doubt that any Dodge dealerships still have anything for you. Mitsubishi MUTII and even the MutIII still has the available adapters and software to read codes from your 91 so i'd suggest you start there. If Mitsubishi is too far away- you can call your local Dodge dealership and ask specifically for the shop foreman to address your concern with scan tool compatability with your 91 before setting up an appt. Otherwise, you'll llikely end up wasting your time.

From what i learned when i worked for Mitsubishi- any time the SRS lamp is on, the system is disabled. A "low voltage" code can be detected triggering the SRS lamp- then be corrected (by replacing the fuse or battery) causing the SRS light turn off. The system will then be ENABLED even though the "low voltage" code remains stored in the SRS ECU memory.
So even with a stored DTC in the SRS ECU, the system can still remain active provided the SRS lamp is OFF. Even reading through Chysler's TSB- the final step of every diagnostic procedure is to assure that the light is off.
