Flashcode 22 is indicating a fault in the drivers-side side air bag circuit. Does your van even have side air bags?? Should be indication on the outside upper part of the seat back cushion with a label.

Only if you want to nickyplumb. About a 1000:1 probability that the fault is within the side air bag sensor itself. If you have a ratchet, 10mm socket, short extension and about 30 minutes of your timethenI see no reason why we could not easily diagnose this for sure and even make the needed repairs to get system working normally again and light off.
Would expect the dealer to probably charge 1 1/2 hours labor plus retail for part if you decide to take it in.

If you are a plumber then I am sure you are good with the hands and mechanically inclined so this should be a walk in the park for you.

One of the best ways to quickly diagnose if a problem is due to a certain component is to just replace that component with a known good replacement and see if the problem goes away. You actually have a known good replacement in the passenger-side side air bag sensor. They are exactly the same OE part number from side to side. If you were to swap the passenger side sensor with drivers and visa versa then if the sensor itself isfaulty, you would no longer be getting a 22 flashcode but instead a code 32 (passenger-side side air bag sensor circuit) indicating fault had moved with the sensor and new sensor should get you back in business.
Getting to the sensors is very easy. They are located near the floor behind the lower B-pillar trim panels (this is the trim piece between between the front door and rear sliding door that extends from the carpet to about half way up )

First thing to do is to disconnect the negative battery cable for 5 minutes so that there will be no power available to the air bag system. This will prevent any accidental deployment of air bag when disconnecting sensors. (Not that it would probably happen anyway but is a good precaution).

Start by removing the front door scuff plate. Just pull straight up on it and clips will release. See first drawing below.
Now open the sliding door and remove the rear scuff plate in the same way as the front. #2 diagram.
Slide the front seat all the way forward.
Pull the front and rear sliding door weatherseal away from the area of the lower B-pillar trim.
Pull the lower B-pillar trim straight away from body to remove. #3 diagram
At the very bottom near the floor, just below the seat belt retractor is the sensor you are after. Last picture below. Electrical connector has a slidingsleeve near the sensor. Just slide the sleeve away from the sensor and connector will release. Remove thetwo 10mmbolts and it is out in your hand. Mark with X so it identified as the suspect faulty one.
Repeat with thepassenger side, swap the two modules, reconnect the battey, and start the van, If flashcode is now 3 long flashes followed by 2 short ( flashcode 32 ), then order up a new sensor to replace the faulty one.
OE part number is LC62-57-KC0B ( that is a zero and not letter O in part number) dealer retail is $87.25 but available from www.onlinlemazdaparts.com for $69.80.

Pull the front scuff plate upward, then disengage clips A, pin B and hooks C from the body, and remove the front scuff plate.

Pull the rear scuff plate upward, then disengage clips A, pin B and hooks C from the body, and remove the rear scuff plate.

Here is the side air bag sensor below the seat belt retractor.

Could upload one more pic so here is one disconnecting the sensor connector.

I have the exact same code flashing on my 2000 MPV, although it's intermittent. One day the darn thing will flash, the next day it won't. Would you recommend the same diagnostic procedure here? I recently replaced the whole airbag computer (well, sometime last year, thanks to help from babyhuey) and was hoping that it wasn't in the computer again. That thing was expensive.
