I've just found ECU from unknown truck.

ECM is by Detroit Diesel. Help me to learn what the engine this ECU for, and its wiering diagram.

Label:

DDEC IV 6 cyl / 12 V only
ddc part #: P23519307
MOtorola model: 6DD4307E02

Thanx!!!!!

 

That's from a late model Series 60. Earliest use was probably 1998, latest use probably 2003. My '96 is DDEC-III, and the 2004+ use DDEC-V.

It's a 6-cylinder diesel used primarily in North American heavy trucks, at least in initial service. They can show up anywhere in the world for the 3rd, 4th, and subsequent owners. They're also used in marine power applications.

On-highway ratings are typically from 350 - 550HP. 350-470HP are 12.7L displacement, and 500+HP are 14 liters displacement.

The Detroit Diesel webpage service locator:

Shows two Detroit Diesel service locations in Moscow. Unfortunately they don't show any locations for Ukraine.

It seems to me PACCAR used these diesels on DAF 85-95 trucks (konwn in America as Kenworth). I'm not sure becouse there were Cummins engines under the DAF's cabine. May be DDEC fits Cummins? Pricipally possible, becouse they both use pump-injectors, like Volvo-truck.

I don't know why, but Detroit Diesel is rare here, but cummins is widly used in Russian trucks and Ukrainian buses.

 

No, DDEC is Detroit-specific. Cummins will have their own ECM. Someone would have had to do a LOT of hacking to get a Detroit ECM to drive Cummins injectors, if it would have worked at all. They *MIGHT* use the same microcontroller (that is, the chip(s) inside the box) but the sensor inputs would be different, and what the programming DID with those sensor inputs would be different. So too would be the plugs on either end of the wiring harness.

Paccar used a lot of Detroit engines in American trucks during the timeframe you suggest.

Well. Thanx! I try to sale it. I hope there is no immo function it this ECU.
