CEL code reader

Anyone have a recommend OBDII for the Cummings 8.9? I have a CEL and want to capture the code myself before taking to service.

Our coaches have the J1939 port instead of ODB2. I ordered the bluefire reader (green plug) that supports iOS. If it works you can borrow it

Awesome!

I was also able to use the documented procedure to query the fault codes through the informational center. However, it cleared itself, so having the reader might give me the previous codes!

does it have the obd port or the round 9 pin deutch connector?
