Had this exact issue in my identical 1993 white Miata. Turns out, if you don't care about the airbag, there is a simple fix. Unplug the connectors from the airbag control module, pull the plastic inserts out of the connectors on the car side (this allows some pins to short together), and no airbag light comes on, no trouble codes reported. I did that many years ago now, and I did actually pull my old module out which was painful to say the least. I opened it up, and it did have the normal problem for them of the electrolytic capacitors leaking all over the board. I tried replacing the caps, but the board was fried already at that point. I have a replacement Ford module out of a '93 Mustang that I will be trying out this weekend to see if that fixes the issue. It is the version that has the battery built in, so no need for the second blue box that is needed for the stock module. Lots of places have said it works perfectly that way, we shall see.
@@robsrestorationgarage The Mustang module was likely bad as well, I did manage to source a replacement from a Miata for far too much money, and it works like a champ. One thing on yours I noticed is that your airbag light does not come on at all, it should come on showing the self check is occurring, then turn off. If it doesn't blink after that self check, you are good to go. Mine is now working properly once again.
I have a white 93 NA, I'm the original owner. Kept it in the garage all this time. Mine has power steering and it's automatic. I just put a Cat Back exhaust in it along with a front grill and front air dam, some mud flaps and door sills. It sounds real sweet! I have the air bag issue as well. Took it into Mazada for a dignostic check several years ago. They no longer make that module and they set my car so the air bag light no longer blinks. Enjoy your Miata!
@@robsrestorationgarage It is also trivial to do. Unplug the module, pull a couple of plastic inserts on the vehicle side of the connector, and no airbag light ever again.
Im more of an NB Miata (or ND2) guy myself, but of course you can never go wrong with the classic NA! So much cool stuff you can do with that car. I love Mazda really in general. Great get!
@@robsrestorationgarage hey, even stock or lightly modded, they tend to be fun - tho I think they excel most as a cost effective blank canvas. Build out internals, K swap, even the Rallycross builds I've seen seem awesome and pretty successful!
I am not sure how much of that I will get into. I tend to not want to mess with a bone stock car that is in really good shape. My plan was to keep the Miata until I finish the Midget and then make a decision from there about its future.
I have a 1993 Miata. The air bag just started flashing on and off when I drove it home from being detailed yesterday. Any suggestions. I live in Cincinnati area and would love to reach you directly if possible. Thank you.
So if it works correctly the air bag light shouldn’t be illuminated at all even when u just open the ignition like the other lights ? Or is it supposed to to turn on temporarily
I have a stock 93 Miata . My air bag light turns on when the ignition is turned on , then turns off after a few seconds. It’s my understanding that if it never turns on it is not working.
@@The44smileyes you are correct. A lot of people just disconnect the sensor or light which means the airbag doesn’t work. I wanted mine to work as it should which is the reason I went the route I did. If yours turns off you should be fine.
@@robsrestorationgarage It should absolutely turn on when you start it, then turn off and stay off. That is what mine does now that I replaced my module, and what it used to do before mine went bad. I would be concerned that your replacement module is not in fact working correctly.
Thanks so much for this! I have a White 93 NA as well and recently I've had a three blink code that turned into a four blink code and I'm worried it's going to blow a fuse. Do you have any suggestions? Looks like an s-sensor from what I've seen online but I'm not sure if I should buy a whole new module or what not. Thank you!
You are correct that a 4 is a faulty sensor. You could replace the sensor which I think is in the bumper. This is different from the control module that I replaced.

Let me know if it works. My replacement module will eventually go out and I will need another solution.

That is definitely one way to do it since the replacement modules are getting harder to find.

They are fun cars to drive for sure. Not sure what I will do with it yet.

I don’t think the airbag light comes on at all even during the start up process

@@robsrestorationgarage ooo shoot okay! I was thinking it was the same one you replaced. You saved me all that hasle. Thank you!
