Have you looked at if you have a J1939 or J1708 port under the dash? Your coach is 7 years newer than ours, you may have more engine ECU data vs our limited data from ALDL, particularly lacking speedometer, primary and secondary air pressures, engine load, turbo boost and fan speed. I wanted these but unavailable . I am aware that ALDL was primarily tailored to Allison trans diagnostics.

Does anyone with a CC gets these from the port under the dash?

Update - Using repair tool I found out the cause - the data is there but it keeps disconnecting within a minute after manually reconnected even though the tablet is just 2 ft from the adapter. Looks like a USB connected version such as Scangauge is better.
