yanmar 4jh57 can buss

[David B]

Sounds like a good project. I have wondered about this for myself. We have full Raymarine instrumentation, and a Yanmar 4JH4TCE.
Can anyone advise if that engine has the necessaries, and what data I could expect to pull onto the Raymarine MFD (E90W)?

Adding N2K to a mechanical 4JH4TE requires a device to connect to the various senders to collect the analog signals and turn them in to digital. Various vendors are out there, but it's a completely different project than the one being discussed here since the 4JH57 is natively an electronically controlled common rail engine.

Thanks for the advice - will pursue when I get the time. Sounds like my project would be simpler in many ways, so that's encouraging.

Based on one suggestion in this thread, I did find the ECI-100 interface online, which says that it is compatible with your engine 4jh57.
Yanmar Engine & Steering Connection Guide for the ECI-100 | Raymarine

It appears to be priced at $300. I'm still confused how it connects to the actual engine, though. My 4JH surely doesn't have a NMEA2k coax connector just sitting there, and the diagram is, to my eyes, unhelpful.

VICTORY!

Engine 4JH80 - 2015 vintage
Control panel - C35
MFD - B&G Zeus2
Gateway - Maretron J2K100

--

I went with the Maretron as I have found thier products to work.

The gateway is a one way only product. I like that!

The J2K100 has 2 CAN ports. Both use an N2K connector. One port speaks J1939 and the other speaks NEMA2000.
J1939 and NEMA2000 are just languages that are carried on the CAN bus. The gateway 'just' takes the J1939 engine messages, translates them, and broadcasts them on the N2K bus.
Both the connectors on the J2K100 are wired the same from a CAN side.
This means that for the engine interface I can just take a CAN cable, cut off the end that doesn't plug into the J2SK100 and put on a suitable connector for the engine.

I tried 2 places on the 'engine'. Both worked.

--1--
On the back of the control C35 panel there is a 4 headed Y able that links the tack to the pressure guage and oil temp guage.
This Y cable is carrying the J1939 to the guages.

The plugs on this cable are 4 pin Delphi / Packard GT 150 connectors.

I ordered up the parts from Mouser ...
- 15326820-B body
- 15373402 pins. You need at least 3... but get some spares.
- 15418546-B - secondary lock.... not srictly necessary but nice.

On the n2k cable that will carry the J1939 to the gateway crimp 3 pins. Black, white and blue. Cut the red wire back as it is not needed and tidy the cable end.
Insert the newley crimped pins in the body so that
- black - goes to the Y harness black
- white goes to yellow on the Y harness
- blue goes to green on the y harness

Then plug, cable tie and make nice the cable routing and YAY ... engine information on the n2k bus.

If you have a B25 panel I believe you don't have the Y cable. In that case you will need the femal plug version of the above connector and plug into the back of the tac.

--2--
On the engine diagnostic connector which is about where the control panel plugs in.. there is a series of 3 connectors arranged vertically.
grey 12 pin - control panel
green 12 pin - aux control panel
grey 6 pin - diagnostic connector.
All 3 of these connectors are Deutsch style connectors.

The diagnostic connector is a pigtail and is 'stored' on the engine in an empty socket.
I got a grey 6 pin connector set from a vendor on Amazon. I took 3 male pins. and crimped them on a NEMA2000 cable I had cut to lenght.
The I inserted the deutsch pins into the empty socket on the engine, installed the lock I got with the connector kit.
- black - goes to the engine black
- white goes to yellow on the engine
- blue goes to green on the engine

Again this worked flawlessly.

------

I decided in the end to go with method 1 as the cable routing was easier and it left the engine diagnostic connector usable.

Hope this helps!

I would mention that it is extremely important you don't cut off the 6 pin diagnostic connector, otherwise your friendly Yanmar dealer will not be able to hook up their YDT tool.

No one was suggesting this...

Brian, THANK YOU, will order parts (again thanks for part #).

Brian, one more question. Maretron has a 4 pin cable part # MCF-2M-D4 would this work?

Unfortunately that cable won't work.

But .. A couple of updates....

A friend of mine attempted to follow my lead and found that in his system it didn't work.
We traced the difference to the main guage in the instrument cluster.
My guage seems to be passing the J1939 messages. His seems to be filtering the messages.

I only have a NMEA2K analyser .. but I see far fewer messages between his instruments.

For his system he purchased a :-

Maretron J2K100 Adapter Micro Female - Deutsche 12 Pin 2T [MCF-2M-D12CAT]

We re-pinned the the connector.
Check on You-tube a small flat bladed screwdriver will allow you to move the pins around.
On the as bought cable.
Pin 7 needs to be swapped with 11. Pin 8 needs to be swapped 10. All the others stay the same.

He plugged the this in between the harness and the terminator and got his system working.

Realize this is n old post but just in case you can buy these for about $200 now seamlessly integrates with B&G and you need an extra cable for Raymarine (I’m told). https://yachtdevicesus.com/ No affiliation but I’ve seem them work it’s amazing rpm, fuel burn, all temps etc etc disputed on your chart plotter

[davedindubai]

I’ve bought all this kit months ago but it’s still on my job list... ooops.
