2014 Freightliner Cascadia DD13 Engine Swap Problems.
Engine starts but won't stay running without an override.
Damaged Original DD13 Engine Serial # 471927S0211556
2014 Freightliner Cascadia Vin # .....ELFP5206
Engine Year Manufactured 2013
Replacement DD13 Engine Serial # 471927S0348234
2017 Freightliner 114SD Vin# ......8HHK3599
Engine Year Manufactured 2015
Used Original wiring hardness and Original ECM with Replacement Engine.
Is the wiring harness bad or the ECM?
Do I need the ECM from the replacement engine?
Hasn't ran long enough to warm up in order to trigger some of the fault codes and that is why I think it is something else besides faulty sensors.
Deleted Codes and they came right back.
Currently 7 Engine Faults on Replacement Engine
SPN: 3510 – Sensor supply voltage 2 FMI: 4 (Voltage Below Normal)
SPN: 94 – Engine Fuel Delivery Pressure FMI: 4 (Voltage Below Normal)

I would have to talk freightliner on that one. I'm pretty sure they could tell you where the hiccup would be with the difference of wiring between the two chassis.
Bluto04 Thanks this. -
Check the harness. There must be one or two connectors. Check them. With DL trouble shoot each code. What i think one of connectors are not in place...Bluto04 Thanks this. -
Might need the ecm from the 2014 . Are they both the same emission level?
msh Thanks this. -
