Computer Diagnostics Code

[bobrow01]

Can anyone tell me how I can get the code to get into the diagnostics in my Mandalay RV?

Should be a port some where under the dash on the right side of the steering wheel the other option is call the factory and ask where they put it

It's called a ODB connector, or ODBC (On-board diagnostics connector). You can buy a reader for under $100 (amazon, etc). Or you can buy a Garmin EcoRoute HD module, which is also around $100 (this is what I use).

If you buy the Garmin device, it consists of a diagnostic cable that connects to the vehicle's ODBC, and a bluetooth transmitter. It will connect to many (but not all) Garmin GPS nav systems that will not only give you diagnostics data, but real-time engine operating parameters (RPM, oil pressure, etc).

And perhaps the best part... it also transmits fuel flow data (as do most of the other diagnostic readers I think).

However, the beauty of connecting it to a Garmin GPS (I connect mine to a Garmin RV760LMT - in vehicle mode), the GPS data can give you real time and accumulated MPG.

And if you don't have a compatible Garmin GPS you can download a Garmin Mechanic app free that works on Android devices to read the bluetooth data from the Garmin EcoRoute HD. For some reason though, iPhones or iPads won't work.
