Title: Engine Warning - where is the diagnostic plug??
Post by: Frederick Thornton on September 18, 2020, 12:08:46 AM

Hi, I have a 2007 Beaver Contessa Bayshore with Cummins 400 engine. For a second time, the Engine Warning light has come on and the tachometer goes to max reading. I pull over, turn the ignition key off, then restart the engine and everything seems ok. The first time this happened was about 2.5 months ago. It happened again yesterday. I am camped by a retired Cummins engineer who has a engine diagnostic device but we don't find the engine diagnostic plug. Can someone tell me exactly where it is on the 2007 Beaver?

THANKS!!

Fredrick,
Remove the panel on the top of the dash in front of the driver. It is tucked up in there (at least it is on the CAT engine units).

Fredrick, Either the data port is under the panel on top of the dash or in the engine compartment. With my PT the trans data port is on the top of the dash and the motor (Cat) is in the engine compartment.

I removed the panel over the dash and there are two plugs, one a six pin and the other a nine pen. I think my Cummins guy said the engine was probably a nine pin. When he returns, I'll get hime to look.

THANKS to both of you for your quick responses!

Not sure that your coach is the same, but perhaps this image of our Monterey will provide some insight.  I think there’s another engine plug in our battery bay.

Thanks Joel, I found the plugs under the dash access panel. It was not exactly like yours, but there were two plugs. I should hav taken a picture! The guy I met couldn't get his 9-pin plug to connect to the nine-pin due to room, and since I was leaving and he just volunteered to check, we didn't try to get better access. Guess I'll have to get an engine shop to check it.
