DME and aux fan error

There is another thread on here where I provide a ship ton of info on that.

Of course, the foxwell commands go through the ECU, so if you really do have a problem with the ECU or the wiring, failure will not be conclusive.

ok...so, I just got another Foxwell scanner (530)...and I'm hunting for this exact menu. Can you give me the tree? I've gone into Diagnosis, DME...but no active test menu. It gives me ECU info, Read Codes, and Clear Codes ...

If post #18 above does not answer it for you, then I don't know. Good luck.
