Air Bag Blink Codes

May 23, 2006 4 Replies

Hello all,



I've got a 91 with 2 concerns:



AirBag light blinks 4 times and sometime 5 time. According to the miata.net web site 4 blinks is a Faulty "S-sensor" and 5 blinks is a Faulty "D-sensor" What is an "S-sensor" and a "D-sensor"?



Second problem is the headlights. When I turn on the lights the headlights no longer pop up. I have to go to the emergency switch on the dash. When it is wet or very muggy out the lights won't pop down when I turn off the lights or when I use the emergency switch on the dash. I have to manually crank down on the headlight motor. The repair shop is telling me that the emergency switch is the only way to make the lights go up and down and the switch is bad. I don't quite understand?


With your problems, you should poke around the garage section in miata.net. All will be answered! (maybe) in far more glorious detail than is practical here.

and third paragraphs are the most helpful for you...:-D My first thought is that somewhere some water got into some electronics and started shorting things. That would explain the faulty sensors and the non-working lights. Just the same...while contrived in design, the Miata headlights were some of the most reliable flip-ups in the business. You'd have to have gotten some serious fluids in there...or accidentially unplugged some things! Have you been dash diving lately? Maybe you knocked a connector with your knee? Or perhaps you unplugged some things under the hood? All speculaiton...just to get you thinking.

My other thought (for the lights) is that there's a short or a connector is coming loose in the stalk itself (where you say "HEY LIGHTS, turn on!") Are you having issues with any other lighting functions? Signals, brights?

Slowly try ruling things out.

Also...take a good long time to browse the miata.net FAQ

1215&highlight=airbag+sensor You should be careful that you're getting the correct airbag codes. I know, for example, that my "solid on" light in my 96 means something other than the same code in other cars...just be careful...these *are* airbags.

Best of luck.

It sounds like you have either a bad switch or bad connector(s) for the headlight motors. I would suspect the switch on the steering wheel column since the headlights work properly with the dash switch. I would also suspect the connector nearest the headlights OR the 30 amp switch in the fuse block under the hood.

Definitely sounds like water is getting in somewhere.

Where exactly is the airbag diagnostics module located in a 93?
