Hey Mr. Mod.... post a link eh

I teach by example, learned that from Beow.... errrrr...... never mind....
okay, I'll bite on this one.
Point:
I honestly don't know what Toyota would be "inspecting". In that link from Riley, offroadkid hit the nail on the head. The diagnostic unit checks for a proper circuit each time the vehicle ignition is turned on. if something is detected, your airbag idiot light would go on. There should be nothing else to check.
Light reading on airbag systems:
As a Mfg. Engineer in the Automotive field, I've built every component in an airbag system (airbags sensors, diagnostic units, inflators, and bags themselves). Nearly every item in the airbag system is hermetically sealed with the exception of the diagnostic unit, bag, and the wiring between connectors. The system as a whole should be good for the life of the vehicle but he reality is that between 20 and 30 yrs, there's a 50/50 chance of it working on pre-1990 vehicles. After and around that time-frame, the sensors started to become all electronic and all components reside on the inside of the cab.
In the good 'ol days, all the sensors were electro-mechanical which resided in the engine compartment. Stated design life is dependant on the vehicle make and model as almost every vehicle is different and used unique (and sometimes strange) methods for sensing a crash (>17mph). typical guaranteed number of years is something like 15 yrs on avg. What eventually and inevitably prevents the system from working on older units is moisture. All salt-spryed snowy roads will eventually 'wick' water molecules into the sensors and stop them from working (ie rust). Moisture can also break down the inflator chemicals (sodium-azide, gels) and make them lose thier punch (so to speak ).
So the point here is pre-mature inflatalation is extremely rare but trying to make it rise when you really want it to can be difficult when the vehicles reach that golden age :whoops:

doesn't your car do a prelim check right before you turn the key on the ignition....and as everything is good to go, the lights all come off...somethign wrong, it stays on...ie....seatbelt not on, light for it stays lit on the dash....luckily my 93 doesn't ahve an airbag...
I have a 95 Tacoma with an airbag that "should" be inspected.
Honestly, I think if I took it to the dealer, they probably wouldn't know how to "inspect" it and tell me that I needed to change it altogether, regardless of whether it needs it or not.
There has to be a Toyota mechanic on this board that can tell us what the normal procedure is for the 10 year airbag checkup.

I would think that the on-start diagnostic may check the electronics but wouldn't know a thing about the condition of the "explosive" or bag. But then, not obvious how the dealer would know either... So, not obvious.
Still, be a bummer to get into a crash and the thing doesn't go off....
Somebody call a dealer and ask, furr cryin' out loud!
