I had error 12 and 51. I found a disconnected plug under the driver seat (occupency mat). I repluged it, and the error 51 is gone, but I still have the error 12. My batterie and alternator are 100% functionnal.
I checked all my fuses (in cabin and under hood) and they are all good.
I would like to probe the module to see if there is voltage on pin 13 but I don't know where it is located.
I saw a light blue-greenish plastic box under the dash, driver side, inline with the headlamp switch that has two connectors, is it this one?
Is there a reset possible on the airbag system?
I was reading on a Mustang forum that those cars (same era) had a 2 pin connector behind the glove box, that you had to jump a wire between the terminals to reset the airbag module.
Does our vans have the same, if yes, again, where is it located.
i believe you have found the airbag module aqua colored box with one white and one black plugs. this is from a 95 bronco

to remove plugs on one side in the middle there will be a tab push with a screwdriver and pull module. now as far as testing or resetting i haven't the slightest clue. i personally don't trust the things anyway. good luck hope you fix it
Here is an update of what I found.
1. The plug under the driver seat was unplugged. I reconnected it, and now the code 51 is gone. Only code 12 is left.
2. I opened the air bag controller, and found that the thermal fuse was blown. I bought a new one (168*C) and reinstalled it, but the code 12 is still present.
I checked at the controller's plug, and I have 12V feeding the box, and the ground is good.
I rechecked the thermal fuse to make sure it was not blown again, and it is still good.
Code 12 means that the controller doesn't see batterie voltage, but everything seem to be ok.
I have no more ideas.
