Yes, I was hoping that the "reset airbag" OBD2 (set of) command(s) would be generic and using any ODB2 code reader would work.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
Any update?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
Thats one Bad ass engine scan toolIts time. Thanks again Toran
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.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.
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.I didn’t check voltage but drove it about 10 miles.

Nope, its a different language compared to the standard ODB2. You will need something that understands it.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....)
