Yeah, it comes with a jumper that will give you 10K Ohms, Short out pins A - B (for "paper clip mode" or setting IAC), or leave it open.
Yes, the 10K resistor is for TPI or some earlier TBIs but, GMt 400s don't use it. It'll cause higher Idle RPMs like @scott2093 mentioned.
So, if I get the cable you previously linked it would have the 10K ohm resistor already? So if I understand correctly the resistor and such the cable will put the truck into diagnostic mode, That would mean the only difference is really that the truck would idle worse, but I could drive with the tuner connected it would just be in "field service mode" right?
I don't think you'll need the 10k in circuit if I'm understanding correctly. And actually, the settings for all the tbi trucks in my 1320 adapter shows to keep the resistor out of circuit. But who knows...
No, you don't need to use the resistor in our case, it'll stream data all the time with Key On, Engine Off or running. You just use the jumper to short pins A - B so, with KOEO you'll see the diagnostic flashes, starting with 12. You can also use it to reset the IAC and min idle screw. Here's a .pdf on how to do that...
That is the question.... may be some Innova specific pinouts only their scanners use goofing things up?? idk...
Yes, it plugs in 3 different positions for zero Ohms, 10K Ohms, and open, like you pulled it out completely, that position is simply a place to park it when not in use. Make sense?
Okay that makes a lot more sense now, thank you. Hopefully the cable comes Monday and I can see what is going on. Truck started to misfire on startup again and surges a bit when Im barely on the gas and now I noticed a ton of carbon in my passenger exhaust, maybe from the misfire.
