Error internal to the ECM related to memory hardware failures or internal microprocessor communication failures.
This usually means that internal microprocessor lead cracking is the cause,,,replace ECM.
Engine might die. Possible no start.
also may log faults codes 434, 442, 213 & more.
Also while in service tool monitor screen & actual battery voltage can jump from 12 volts to 28 volts.

Engine won't start & no power to the fuel solenoid.

Customer email reply:

Hi Terry


Sure glad I took your advice on everything you told me to do before I installed your ECM.
Especially telling me that I needed a new ECM, cam sensor, fuel solenoid & engine wiring harness.
You were right on Terry!
We installed the complete engine harness, cam sensor, and ECM and she fired right up.
Great ECM Product and Tech Support!
Best money I ever spent on my truck, runs great, better than she ever did before!
I'll be spreading the word.
Thank you for the help!

Jason

Customer Problem:
Stranded in
República Dominicana
Engine Change over Celect Plus to Celect Engine
Engine won't plug up & wrong ECM.


Hi Jose
I see that your engine was manufactured in 1993 CPL 1669-L10-330hp
Now we need to make sure the ECM that's on it is a part# 3619037 or a 3618046
This is very important and helps tell me what harness and ECM/ calibration we might should use.
This is important because the plug on the engine and harnesses must be correct or everything is wrong if we guess wrong on this one.
That means the harnesses and ecm will not plug in to the OEM Connector on the truck
The 98 freightliner probably had a CelectPlus OEM harness, being a FRL. 98 glider kit.
So, did someone change the OEM plug to fit the L10 engine harness/ECM or di someone put a new CelectPlus engine harness in place of the original L10 harness with a CelectPlus Harness?
This info will help clear up the mystery


Hi Terry

We want you to put together a new ECM and the harnesses and any other components we need?

Thanks Jose
 


Hi Jose

I'm sending you The ECM, Engine Harness, cam sensor & fuel solenoid.

 

Hi Terry

We got everything today and finished rewiring ECM supply and put all your parts on like you said.
Just wanted to tell you that the truck fired up without no problems!

 

Hi Jose
I get lucky every once in awhile
Have a great day!

Hi Terry

To me that wasn’t lucky, it was a thorough research from your part.
We got everything you recommended, the ECM, the harness, the sensors, the solenoid, just like you recommended.

So you’ll know, since the day the ECM arrived first, we installed it to try it and surely enough the fuel solenoid gave out, so as soon as we got the one you sent us it worked like a charm. You can expect recommendations from our behalf!

Thanks again, your friend Jose
