93 corolla air bag & Module replacement

[Cobnobuler]

Hi again all,

I was searching the threads looking for the correct info on airbags for a 93 Corolla and I'm not seeing it specific so I thought I would ask here. I need to change the airbag and module after my sons curb incident. I've never done this before either so a few questions:

I know to disc the battery !
I understand the module to be in the console somewhere near the center? Does anyone know is it in front of the floor shifter under the carpet? Its an automatic.
Also is there any order to changing the bag and module? I figured with the batt disc it shouldnt matter either way?
I got both the "new" airbag and "new" module from the junkyard. They do look good though !
Any tips on this installation would be appreciated !

Thank you

Cob

By module I assume you're talking about the airbag computer. You shouldn't need a new airbag computer, but it's behind the shifter, right under the arm rest (if equipped, if not the best reference point is the e-brake). You might want to replace the airbag sensor that tripped the airbag, seeing as it had to be damaged to do so. However, I'm not so sure on how to replace the actual airbag.

As I'm understanding it, once the airbag is deployed, the computer either has to be reset or replaced. I of course never knew it existed, the guy at the junkyard that gave me a new bag said not to forget this piece too, it goes with it he said.

The computer would need to be replaced. Also, there are 2 sensors in the front bumper (I believe one on the passenger side and one on the driver's) besides the one under the center console.

Is that going to matter in replacing in this case? It was hit on the front pass wheel only. My hope is that by replacing the bag and the module (computer) at the same time, I'll have a bag that would work if needed, and put out the 'airbag' light on the dash as well.
Or, is there any other code sweep or something when replacing the bag and module?

Thanks for your input``

Unfortunately, yes. When the air bag deploys, you'd need a new steering wheel, air bag, sensors, and computer (this is why insurances companies "write-off" cars where the air bag has been deployed, because the cost to fix can exceed what the car is worth). Reason for this, not only do you want the Air Bag Light to go out, but also the air bag to work in the event of another acciedent (hopefully you would not have anymore), and also so it does not deploy inadvertently. I'm not going to steer you wrong, so if you're unsure, call some repair shops and see what they say. Good luck

Finished this job after finally getting the right module. The junkyard cowboys gave me a module from a 94 and it wont fit the 93. First year of the double bag in 94 so it turns out. Anyway, changed the bag in the steering wheel, changed the module, and did nothing else to the sensors in the bumper and it went perfect. The light came on to say its active and then went out and didnt stay on. High fives everyones happy, the 93 is back on the streets with 150K and many more to go...!!

.....and to think the place that towed it off the road then buried it in snow thought I was gonna just hand them the title to her...Ha...think again.

Glad you got it fixed.

My 93 airbag light is on but I don't know if it has an airbag. The car had some front left corner damage and there is red paint on the airbag cover (I think it said "no airbag" or something).

How do you verify the airbag is in place?

[zythr]

You'll need to take it to a repair shop and have them test to see if there is one. Unless you know what you're doing, the air bag, if there is one, could accidently go off. Better to be safe than sorry.

You need to reset the computer using this -

This is taken from chris's airbag reset. http://www.cardomain.com/ride/801395/7#Airbag

gold94corollas 1994 Toyota Corolla This diagram shows how to reset the airbag computer for any situation. I paid 40 bucks for this paper LOL. Yours for free. It is kind of confusing, I probably can't explain it with words. Find the little box under the hood marked "Diagnostics". It is attached to the driver's-side strut tower. Open it up, and you'll see the picture in the top left corner of the diagram. Insert two wires as shown that can reach to the - battery terminal. You will ground the wires in the pattern shown. First ground TC, then none, then AB, both, only TC, none, AB, only TC, none. All pretty quick. I'm a drummer so some rhythm helped LOL. You have to do this grounding with the key switched all the way on.



Here's the best I could do to show it under the hood..... the diagram is there, and the TC wire is marked in green, the AB in blue. With the key on, and the successful completion of the tap dance, the airbag light will flash and then turn off if there is no problem. It took me several tried before I got it down pat.



edit- sorry for posting, see you got it already.

[billwagnon]

With the reset tapdance, if the light resets then I don't have a problem?

Also if the airbag is missing, it sounds like the reset tapdance means I *don't* need to get a computer module along with a replacement junkyard.

Thanks for sharing!

[billwagnon]

The diagram looks like this to me - I may be reading it wrong.

TC (release TC)
AB follow with TC (release AB, then release TC)
AB follow with TC (release AB then release TC)
..continue and hit the pattern within 1+- .5 seconds, once within 20 seconds.

Is this right?

[billwagnon]

Hey I finally got around to this and it worked!

Glad to hear it.
