Several of my J1939 modules are enabled by an IDC. These nodes (GT Modul, engine and switchpacks) are not always powered up, so if they are enabled all the time, it will throw a timeout error. The MD4 and the MC43 are both monitoring these nodes. I am getting a “Channel not available on module” error on the enable channel for these nodes. I have tried moving the IDC from the MC43 to the MD4 and neither works. I am using IQAN Design 6.00.49.5414.
Here is my system layout.
