Question IDS Network Fail - No response on the UBP line Pin 3 at the DLC

Doing a "Network Test" on IDS I get a "Network Fail - No response on the UBP line Pin 3 at the DLC" Anyone know anything about this error? Been trying to track down any gremlins in my truck. After reprogramming the PCM(PCM appears to of been pulled from a scrap yard because of the different tear tag), TCM and FICM to the proper tear tag I finally got my VIN to save in the PCM. Pulling up IDS OBD II Test mode 9 my PCM and TCM both show blank spaces. The VSM module fails as well but I'm not sure if line 3 communicates with that.

VIN now has my VIN shown, took 2 reprogramming sessions to get this to take.

I found some references that may help you:

Now you can fix NO Communication problems for 2008 Ford F150 bus network protocol using a voltmeter

The VSM could also be loading the network down.

It's been a bit but you may want to take a look at this PDF.

Just contacted @Motohead911 , he also has the Network Test Fail so this may be due to the fact this isn't a true VCM II or VCM II clone.

You may try disconnection various modules on the UPB network.
As a short would take that network out. Really any of the networks will have issues with a short.

Here is one thing I found when Googling : Ford F-series Network Fail - No response on the UBP line Pin 3 at the DLC.

I have been working on this for awhile now and have found many trucks with a similar problems.

Truck is 2004.5. It will start and idle but is derated. Im thinking its time for a tow to the Ford dealer.

I just checked mine, and I have a failure with the VSM and EATC (which is funny since I don't have an EATC). But I was able to get my info from OBD II Mode 9 Test.
