Does anyone know if the 96 pickups will work with the hptuners scanner software or are they not the standardized obdII even though they have the obdII port.

I've tried my cable on both 96 with a vortec 5.7 and 97's with 4.3l, now im wondering if its the cable or not..

it gives the error along the lines of insure the key is in the on position.

what would the standard error be if the vehicle is not truly an obdII standardized vehicle?


I really did search and did not come up with an answer i swear


Thanks,
Greg
