How are you reading the code (i.e. is it possible you have it wrong).

Since the SRS ECU is new, and the wiring tested fine, if that is the correct code, then the pretensioner has to be the culprit. Before buying another one, you can connect a 3 ohm (make sure it is 3, not 3K ohm) in place of the pretensioner to verify.

For the heck of it, check the connector under the driver's seat for the driver's seat belt buckle. That would be code "37".

Replaced the whole damn seat, tried different wheel airbag and a clock spring, nothing seems to work. This is crazy!

It definitely is crazy. Check that connector now though, as you never know.

The only thing left would be the actual wiring harness.

Can you take a video of the light pattern?

The floor one is the one that goes from the SRS ECU to the pretensioners. I really don't think that it is the harness though, with what I had you test.

I would really like to see the light pattern. If it would be easier for shooting it to me, I can PM you my cell or email to send it to. From there we can go through a step by step bit of testing to try to pinpoint the problem.

I am on the edge of my seat. This is playing out like that Nicolas Cage movie National Treasure. I hope you find the answer, dude.

here is the video! first i jump two pins to read the code (7 and 3 blinks) than i try to erase the code (two attempts) after which you can see when you turn the ignition off for about one second the light functions normal, but when its off for a little longer the light comes back on again with the same code!

OK. I definitely agree that it is code 73, which the service manual says is "short in right hand pretensioner squib". What if that is a misprint, as 73 is short in left hand on many other Toyotas?

Have you perchance checked the driver's side one?

thats the thing.. some service manual say its the right side some say its the left side, thats why i've tried both sides..right now i got the new floor wiring in it, new seats (both sides) new seat belts (both sides) new wheel bag, new passenger bag, new module, and a new front airbag sensors (both sides) the only thing i haven't replaced on that is the dash harness and the wires that go out to the front impact sensors. i am just clueless about this whole thing!

I can't believe that you've replaced all of that. I don't even want to know what you have spent thus far. Let me force a fault on the pretensioner on one of mine and verify that 73 is really correct (and for what side). I will do that this evening...

OK. I had a chance to try it now before I have to run out to meet with a client. Code 73 came up when I disconnected the left pretensioner, the right pretensioner and both. Code 74 never came up. So, that code 73 alone is not particularly helpful in figuring out which side is the issue.

When I get back I will put together a set of instructions for what to do next.

Out of curiosity, did your parts car have one or both of the airbags pop?
