6.6L VIN 8 LML P161A after GPCM Replacement and copy of flow rate codes
Replaced glow plug control module. Copied fuel injectors flow codes to glow plug control module then let power down two minutes per instructions. Checked both ECM and GPCM match flow codes but code P161A glow plug control module not programmed is active. Per repair info copy of injector flow codes was all that was needed. Anybody had this issue before?
You need to reflash the glow plug module it comes with no soft ware in it.

Hi Darren, As Danny correctly pointed out the GPCM needs to be programmed. If you ever have a question - Does this replacement module need to be programmed? GM lets you check what modules are programmable with TIS2Web - tis2web.service.gm.com/tis2web You can also check to see what calibration files are currently in the module and whether or not there…
Yes i own an mdi 2 and have flashed with it. Im currently having issues with it and cant get the laptop and the mdi to talk to each other. Thanks for the reply.
You might take a look at this post that John Rogers put up. diag.net/msg/m6u242jmu5… I'm not sure if this is what you have going on. If all else fails you can call AC Delco and see if they can assist.
Yes you have to flash the GPCM with SPS before copying the flow rates.
