diacom ? talking to ECU's

[Stowe, Ted-SEA]

does a GM 1226867 have any communication capability ?, I have seen threads
about talking rs-232 to the units but I never understood how this got
accomplished and what this would get me.

I would think that if I had the oem socket I could plug in something to help
me with the readout codes ?

thanks, Ted.

How does a diacom work, and what exactly is it's purpose?
