Airbag light stays on

2002 Tacoma
My airbag light stays on. I have a cheapo code reader that I will use to see if it will throw me an airbag code.

Then I will check:
* crash sensors(I'm unsure of where they are located)
* loose connectors under drivers seat(I'm not sure if this is relevant)
Any other diagnostic ideas?

Is their anyone with an obd code reader that is able to reset an airbag light?

I was told the usual code readers will not read an Airbag problem. Only the dealers reader can read those.

 

My horn works fine and I don’t have cruise control. My truck I guess is 1st generation being its a 2002. It’s a V-6 4x4 extended cab.
