yanmar 4jh57 can buss

Trying to tie into can buss on JH57 and found that it requires 2cables that dealer quoted at about $1000. Is there another solution? Just want to get engine info on Raymarine MFD.

Re: yanmar 4jh57 can buss

Can you be a little more specific? What is a can buss? What does Raymarine MDF have to do with a Yanmar 4jh?

According to a thread on another forum it would cost more like $1,800.00.

Re: yanmar 4jh57 can buss

I have the 4JH80 so the slighlt bigget sibling of the present generation common rail 4jh familily.
I am assuming that you mean this family.

Summary -
CAN is an electrical communication bus used in things like engines and boats (N2K is the protocol that sits on the bus).
'We' want to display the engine informaion on the MFD displays

I have been very frustrated by this issue - and the dealers have not been very helpfull.

The CAN bus on this engine is available in two places.
1) On the 6 pin Deutsch connector labled C on the wiring diagram. That is located at the top of the ECU above the control panel cable.
2) On the control pannel (pins 10-11 for signal). I believe there is a spare 4 pin connector here that has the engine CAN bus on. But I haven't traced the connector name.

My assumption is that the engine is running J1939 - the engine information protocol that runs on CAN bus. I have verified that it is CAN and that it is not NMEA2K. ( Using a N2K analyser ).

The 6pin Deutsch cable looks remarkably like the Volvo engine link connector. Even seems to have the same wire colours and locations.
Raymarine make one to plug into their J1939->N2K gateway, Part number E70240. Cable is about $75

Then you need a gateway to do the message conversion.

Raymarine's J1939 gateway (ECI-100) is about $300.
Maretron - j2k100 - $350?
Offshore Dynamics - 3185 - $385 This looks like it would be good in multi engine situations.
(There are probably more but..)

I have the cable and the Maretron on order. (My MFDs are B&G and Maretron setup may be easier on the B&G)
Now the cable may need rewiring to work... this is is not a problem for me.
And the engine may not be J1939 - this would royaly suck. But Raymarine show pictures of thier gateway working in a Yanmar setup. So I am hopefull.

Amazon say the parts will arive this week.
Total about $500 including N2K drop cable.

I will update you all with the progress.

Re: yanmar 4jh57 can buss

Brian, thanks! Hope you find a solution and let me know how it works. Can not understand why Yanmar wants such a high price?

Re: yanmar 4jh57 can buss

I'm glad you guys figured it out. Guess I'm a little technically challenged at times.

Re: yanmar 4jh57 can buss

Note that the Yanmar CR spec sheet specifically lists a converter for NMEA2K for these engines, but I have yet to find a dealer that will deliver the accessory. The spec sheet describes, in the optional accessories list, "NMEA 2000 convertor [sic] for Engine monitory system"

Re: yanmar 4jh57 can buss

Would a Maretron adaptor display the required info?

Re: yanmar 4jh57 can buss

Depending whether you have the full VCI10 control package or just a bare bones JH57 with mechanical controls will depend what exactly you need to connect to an N2K backbone.

In the first instance (full VCI10) you probably have everything you need. In the latter instance, you'll need an ACI-100 interface and harness.

Consult your Yanmar dealer for system diagrams and parts pricing. Maretron is unlikely to be a substitute since every manufacturer adds their own property stuff on top of J1939.

Re: yanmar 4jh57 can buss

Got the ACI 100 from Ray marine, it's the cables (2) that connect engine to ACI 100 that are a mystery. Dealer can only find in Europe. Cheapest is around $1000. Ray marine and Yanmar literature both indicate plug and play but elect diagrams show (2) extra cables, dealer called Yanmar who stated requirement for cables. Cannot understand why this problem has not been investigated before? Why the high price? Why not stocked or readily available?

Re: yanmar 4jh57 can buss

When I looked at the parts last I did see one of the cables listed for about $1000 but it wasn't apparent if you would need that one or not. There were a couple others that you definitely would need costing approx $400.

Where are you located? Yanmar distributors & dealers are regional - I'm happy to help but don't want to step on any toes by going out of area.

Do you have the JH57 and VCI10 installation manuals? I'm sure they answer most of your questions.

Wowee ! Just confirms my belief that any diesel I would own would only require diesel fuel and compression to run.

Oak Harbor Wa. Part number 164000 29000 fig 41 in parts book looks like right connector but probably not. Do not have VC 110 have 38' sail boat no need for VC 110.

Re: yanmar 4jh57 can buss

That part is the can bus terminator and the link that tell the ecu that the control panel is there.
The resistor is just like the n2k can bus terminator that you have.
