Just thought I would run this past you to see if it was expected behavior.
My M130, CDL3, PDM15 and MDD are all talking nicely.
I save the config from the PDM15 (actually read the instructions for once!).
I upgrade the PDM15, as expected everything stopped because it loses the config.
I reupload the config.
PDM15 all working fine.
No CAN comms from the ECU, or ethernet connection. Check the power to the ECU and it is active but got a zero current reading, possibly with flashes of 1 amp.
Try turning everything off/on again, several times, no change.
Disconnect the ECU and plug it back in.
Everything springs back into life.
Any ideas?
