Bismic is on point. The BAFX adapters are what I use. I buy them in batches and give them to my customers so they always have one in their trucks. It’s money well spent.
When they call me, I walk them through some diagnostics. Most of of the time with the info they can get for me using the BAFX and FORScan or OBD Fusion apps, I can walk them through patching their own truck up. Or I can have a really good idea of what parts to have waiting when they pull in my shop.

Well finally got a good scanner to run DTC and found pcm is mismatch vin#. And only other code it through was icp high. And still want start we checked everything ran test FICM injectors glow plugs etc. all good. Did test starting and everything is getting right numbers. But pcm mismatch keeps popping up.

i took bully dog off return to stock when i did test with obd2. ficm key on 47volts during key cycle it only dropped to 46 volts and cranking it was 46 volts. icp graph (pressure vs voltage) looks like this hope its right <font class="small">Code:</font><hr /><pre>Press Press Sensor (PSI) (MPA) Voltage 0 0 .02v 200 1.5 .4v 400 3 0.73v 600 4 .96v 800 5.5 1.2v 1000 7 1.4v 1200 8 1.6v 1400 9.7 1.9v 1600 11 2.1v 1800 12.4 2.3v 2000 13.8 2.6v 2200 15.2 2.8v 2400 16.5 3v 2600 18 3.3v 2800 19.3 3.5v 3000 20.6 3.8v</pre><hr /> . dont ask me what that means just wrote it all down after i took pics of everything. if you need more i will try and get them posted

If you look back in the thread, there is a list of values requested. We would like to help you. But if you can not or will not provide information, then we are shooting in the dark.
All of the the stuff you posted really equates to two of the things asked for in the original list from the beginning of the thread.
Vin mismatch can be a lot of things. Could be a ghost in the machine, could be a code that popped up during programming, that was never cleared. Could be a true vin mismatch from using the bully dog to tune it.
