I don't know if you can check the software revision of your IPC module, back when we were able to get the PTI information from ETIS, you could see the current software and hardware version of the ETIS modules. I have not checked if I can see the information in FORSCAN, but I bet we can figure out what revision changed the ability to program the IPC.I've got a MY21 (delivered in November) and I'm not able to change any IPC settings either. I'm trying to add the factory fog switch and the IPC write errors out at 28% every time.
