I need top be able to access or display DM2 log information from the J1939 engine ECU when multiple FMI errors occur under a specific SPN
First you need to have the 'Enable DM2 support' on the DM1 channel enabled.
Then you get the DM2 via the menu of the MD4.
Go to System/modules/Engine module, and you have a button in the upper right corner where you can get the DM2 messages.
