Location of OBD 2 port

[Marian.]

Does anyone know where the OBD 2 port is located on the 2003 Fleetwood Discoverys?

What is the chassis? That is what determines where the port is.

Have you looked under the driver side dashboard? Might have to crawl in and look up under it.

They are always close to the steering column; I think the federal requirement is something like 30 cm, but I don't recall for sure. Look under the dash on the left side of the steering wheel. Might be behind a removable cover, but on mine it's just dangling.

Your Discovery doesn't have an OBD II port - they are not used on medium and heavy duty diesels. Instead it probably has a SAE J1708 engine data bus and diagnostic connector or it may have the newer J1939 bus. A call to Caterpillar (you have the Cat 3126E engine, right?) or Freightliner should get you the answer which it is. And maybe where to find it too. Most likely back at the engine.

Not really... mine on the car is under a center console cover...

On my 2005 Bounder diesel the engine data bus is above the radiator at the back of the MH. The Cat mechanic that re-flashed my computer today said they are sometimes in the LP compartment.

Engine data bus, for the ECU, and OBD II port, are different things. I missed the part about it being a diesel.

Here's a link to a site identifying the locations of OBD II ports....
