Unable to Connect CM849
I can not get my V2 to connect with V7.5 scanning tool. When I try to log my CM849 the V2 goes into pass through mode then just the yellow LED is lit. The V7.5 scanning tool shows that it is only connected to the V2 box not the ECU. I have selected CM849 before I attempt to connect. Same problem every time I try to connect. I tried to read the ECU with V8 and it gave an error that no ECU was found. I have OBDII dongle that has no issues connecting and sending data to my phone app so I know the OBDII port & wiring is ok. The one thing I can't verify is if a Cummins licensed V2 box is needed to scan. I have not purchased the Cummins tuning option yet. Do you need to purchased the Cummins upgrade to Scan?
