Anyone knows if pin-shifting these to the "standard" ODB2 pins would allow a non-hawkeye code reader to reset the light? (on the '96, if you battery drops below a specific voltage and you try to crank the engine [which I would do since I might not know the battery is weak], you will record a code on the SRS computer, the light will stay on until you reset it and, here, you will fail inspection because the light is on! :/ Not sure if I want to invest on an Hawkeye....)
Ill try to stay out of the weeds on this, but obd2 is complex.
it's probable if you are referring to a bluetooth or wifi adapter. at the top of the stack itll still need custom software or something that will let you change details like the message structure, so the harbor freight scan tool will never be able to do this. it might need to be a more specialized bluetooth adapter like the obdlink models. they let you do more outside the box stuff that no proper obd2 device should ever need (disable auto checksum, disable incoming message verifications, send a single byte with no header, etc)
this is what I intend to solve and open up the definition

Yes, I was hoping that the "reset airbag" OBD2 (set of) command(s) would be generic and using any ODB2 code reader would work.
I havent checked the airbag yet, but the alarm is not going to work with a generic obd2 reader. 15bps init followed by 96008n1 with minimal message structure
Right now Im looking at trying either a reader with the scantool.net chip and a pin shifter adapter, or a hm-10 bluetooth module with a simple circuit to take it from logic level to 12v 1 wire similar to what rovergauge requires and pre obd2 gm stuff used
go a neat breakout board for this. makes hooking it up to the analyzer wire hacking free

Any update?
Got my OBD2 extension cord last week and will modify it for the need.
now…… I’m really hoping that Hawkeye is not needed and I can use either generic adapter (or any easy piece of code to run through something like Rovergauge) or a Nanocom (since I own one)?
Thats one Bad ass engine scan tool
Only thing missing is a glass of bourbon
For making shit happen
I got distracted yesterday and left the ignition on overnight. The battery was dead in the morning. I jump started it with a jump pack and now the SRS light comes on, blinks for a while, and then stays on.
I have read about a connection under the right hand seat but I don’t think that is my issue.
Any suggestions to correct this? This is 96 D1.

Have you gotten the battery back above 12.5 or so with the truck off and re started it? That module hates voltage sags starting it on a dead battery can be enough to make it upset until you power it off and get started with sufficient voltage again.
I didn’t check voltage but drove it about 10 miles. I disconnected the negative cable and will leave it that way a while. I don’t really think that will help but it’s worth a try. I will check voltage before I restart it.
It absolutely may not be the thing, but it's absolutely a thing and an easy one to eliminate so you aren't chasing your tail.
The newer a vehicle you're working on the worse that all gets. I'm at the point where I have a charger hooked up on everything while I'm working on it if I'm gonna be running electronics as part of that, and I usually am as I'll need at least the ECU powered on for live data/2 way commands so it doesn't all go sideways the first time I start it for real after the work is done.
I like the easy button when it comes to things like this. Anybody use one of these and use it to reset the SRS?
Or maybe this one?

I have a very old 619 that indeed still gets free updates and it will absolutely reset SRS codes on my 98. It's one of those "best purchase for the money things" you only realize many years later when you realize how much you've used it and how you haven't spent any more money on it.
Update: No, it won't sorry. I'm confusing it working on my 98 with it actually working on my 2002 D2.

Nope, its a different language compared to the standard ODB2. You will need something that understands it.
Sorry for being late to the party. Two new jobs (one job being absorbed into a new company) and a mild stroke have kept me busy. I have since made a new cable and have the old one I could ship out to a guy in need.
