1990-Mazda miata I replace my 1990 mazda miata airbag because it goes off. How do I get rid of this airbag light to go off?

Question edited for clarity.
Question moved to model category.

Yes, you are correct, disconnecting the fuse box has broken the pairing between the key and the immobilizer system. Did you remove the main connection plugs to the fuse box? My thought is that those connectors have never been removed since the car was built and breaking a remaking the connection, you might have some connections that as not as good as they should be. Pull the connectors again and give them a good spray with electrical contact cleaner (that is NOT WD40). Then reconnect.

There is various ideas on resetting the Immobilizer here.

the best thing to do to check your fuel pump is to take out the connector near to injector then switchs the ignition on if the fuel comes out then it is not fuel pump.if not buy new fuel pump

10 blinks is a faulty diagnostic module. If available at the dealer it will be hundreds of dollars. You do see these at salvage yards and on eBay but remember you're purchasing the same 25 year old part that you had failed so make sure you can return the item if it doesn't work. Airbag Blink Codes

You'll have to inspect the brake light switch at the pedal box assy. Damaged switch or wiring could give the previous symptoms you describe.! Good luck

shouldnt be too hard mate, gather the boys over for the weekend because it`ll seriously take only 2 hours MAX to do.

Jack the kent up and take the wheels off...couple bolts here and there and bobs ya mum.

check that there is a good connection from the earth to body (a lot of electrical problems are earth related) also that the connections on the battery are firm. check that the battery has good voltage.

mcdevito75 here, The Mazda people should have the manual with the picture. Also speak again with the Mazda people.

Ken,
This is a common problem. I have a similar issue with my 92 Miata. I currently have a 10 code problem with my airbag.
You can see the codes and what they mean at:

Hope that helps.

disconnect the neg battery terminal for about 15 or 30 seconds to reset the computor

This is either a problem with one or both of your airbags or the airbag connector located at the back of the glovebox has been disconnected for some reason. (ie. to prevent airbag opening when installing baby seat) (1999 miata does not have a baby seat airbag disabling sensor).

You should get your car inspected at your local mazda service to check if this is a wiring (plug disconnected) issue or one of your airbags is malfunctioning and needs to be replaced.

Flashing airbag light could indicate that either one of the airbags or both have a problem. Disconnecting the passenger's airbag has the same effect.

Warning! Do NOT attempt to do any kind of airbag/airbag wiring related repair yourself. Airbag problems should be addressed ONLY by certified technicians at your local Mazda service. (Airbag fixing requires for example that the car battery is disconnected, you MUST NOT attempt anything with the car battery connected).


Hope this helps.
