...ah the fun part - it's funny seeing how many wires were actually needed to make it run...and how many more were used to make it not run...
I can tell you this that my BCM operated normal with the diesel swap with no crank and rpm signal but mine is a factory manual. I did eventually feed the stock PCM a RPM signal so the factory gauge would work....I guess the question is...does the BCM etc 'need' crank signal (or some other signal from the PCM) to tell it the engine is running...and without it what will it do...but like you said prolly just going to need to work through it all - hopefully it's all moot.
Regardless, when I have the truck running and all sorted out I'll know a lot more about how to "de-computerize" a Dakota
remind me again about your truck - year, specs, major mods?I can tell you this that my BCM operated normal with the diesel swap with no crank and rpm signal but mine is a factory manual. I did eventually feed the stock PCM a RPM signal so the factory gauge would work.
Apology yes the CTM is the what I was mistakenly referring to as the BCM cause thats what it does control the body functions.remind me again about your truck - year, specs, major mods?
On the modules, according to my FSM my '02 truck has 8 Electronic Control Modules (ECM), and if my calculations are correct the only one I'll be keeping/using is the CTM, maybe the Data Link - not sure yet, but everything else is 'not appearing in this movie'. After digging through the CTM info I also don't see anything that really 'stands out' as a show-stopper in terms of stuff not working without driveline connected - we shall see. Funny - a while ago I did a whole thing about how to 'de-computerize' a 1st Gen Dodge Cummins Ram...and it looks like I'm doing a similar thing for a Dodge Dakota...
1) CTM - Central Timer Module
2) Communications Module
3) RWAB/CAB - Rear Wheel Antilock Brake/Controller Antilock Brake
4) Data Link Connector
5) PCM - Powertrain Control Module
6) SKIM - Sentry Key Immobilizer
7) Transmission Control Module
8) Transfer Case Control Module
With all aftermarket gauges you will be fine then.I decided to go with the full set of Autometer gauges/turn signals/high beam indicators, etc., so none of the dash is reliant on anything factory
looked through the site - do you have a thread on your 01 build?
