My ECM fuse blows as soon as power is put on the engine. Once I swapped the ECM from the other engine, the engine operates properly. I need to order a replacement ECM for my Volvo Penta 5.7 GI-J. My 2009 Regal 3360 came with 3594198 installed on both engines. I was told that ECM part number 3594198 was superseded to part number 3594199. Volvo Penta Shop https://www.volvopentashop.com website shows my engine serial number calls for a 3594195.


Please advise which part number to purchase.


Engine part number 3969403

Engine serial numbers 4012253553 4012253554

ECM p/n installed 3594198

ECM superseded p/n 3594199

ECM website p/n 3594195


Thank you in advance for your help.

A very interesting problem. Here is what I see.

3594198 comes up in the Volvo parts system as an unknown number, so I'm unsure how you found that it superseded to.....
3594199 which does come up as the ECM for a 5.7GXi-J. When I run supersession chain for the 3594199 it shows that that number has never been superseded up or down.

But the Volvo system says your serial numbers belong to 5.7Gi-300-J engines and those engines use the 3594195 ECM

Your engines are to old for me to see the "as built" parts list, so I don't know what they shipped with new.

Unfortunately my best advise is to ask your dealer to call Volvo tech support. It's possible that iBOATS may be able to call or email for you because they are an authorized supplier of genuine Volvo parts. I would sure get to the bottom of this before risking having mismatched ECMs on a twin engine boat.

Muc,

First, thank you for the reply and the lead for ECM repair. I have attached a picture confirming ECM p/n 3594198. While searching for 3594198 one website linked me to 3594199. I have a call into Regal to see if my engine was delivered with the wrong ECM part number. This is the same ECM that gave me a code SPN 710 FM:4 (Problem with Ocean X system). Ocean X system is not installed on my boat. https://forums.iboats.com/forum/eng...drives/10806483-volvo-penta-5-7-gi-2009-alarm

Some of the problem is the part numbers. Volvo sells ECMs as a kit. The module and decal/calibration
The 3594195 is the part number for a kit. This kit includes 2 pieces
21211981 MODULE
3594196 DECAL

3594199 includes
21211981 MODULE
3594200 DECAL

The decal part number isn't available separately and comes up as unavailable.

I'm guessing 3594198 is the part number for the decal. So I would think your ECMs have a different calibration file in them.
I think you will need to call Volvo, I don't think Regal will be much help with this.

Did you ever get the previous problem resolved?
