A few GM SPS issues
I’m lumping 3 issues in this post hoping for some feedback and also that someone in the TLC department may see this and address an issue. (Wishful thinking??)
While I was flashing a new cluster in the linked truck for a shop the module list had two ”IPC“ modules listed with no distinction between the two options. Selecting the first using “Replace & Reprogram” got me a pop-up “Make sure the original module is installed” which it was not. (It was not available). I was able to get out and try “Reprogram” as opposed to “Replace & Reprogram” and ended up with the same message. Again I was able to get out (I didn’t see the back button that we used to have). I selected the second IPC module option and “Reprogram” and it went through smoothly. Seems to me the first IPC option must be used when inhale/exhale is an option. I looked up the VIN on GM Cal ID and it only lists one IPC option. It would be helpful if a descriptive gets added to the SPS2 module list to help techs select the correct option.
I don’t have an active GDS2. I‘m finding that the SPS “Clear DTCs” button that used to work for me with SPS1 doesn’t work anymore so I need to connect a scan tool and go through the clear codes process.
And lastly, for some time, even with SPS1, my laptop disconnects from my iPhone hotspot while running SPS. Oddly it doesn’t do this with other applications or browsing other websites. Asking around, it seems I’m not alone with this problem.
I've experienced all three of these as well, so I'm eager to hear how it gets resolved.
Usually one is listed for “Reprogram" and the othe IPC selection will be for “Setup”. Aka… writing the mileage and Eng Hours to the cluster after you have programmed it with the correct OS and Calibration.
You’re likely referring to how we both remember the way it used to be. Both options were listed as Instrument Panel Cluster.
I too could not use the clear codes function this past Tuesday after flashing a Cruze PCM…
