No data to vessel view mobile module

[chsapeak]

Let me first say my 2010 opitimax outboard lost communication with my smartcraft gauges. After unhooking and re-hooking every connection several times and still receiving the "lost engine com" error on both my tach & speedo, I decided to hook a vessel view mobile directly to the motor harness. placing the terminator cap on my short VF lead. when I turn my key on I get three blinks of both lights on the VF monitor and then only my bluetooth light remains lit. No smartcraft green light. On a side note when I was troubleshooting the gauges, I removed my tach from the dash and placed it directly to the end of the helm harness, removing the jct box from the equation. still no worky. After a master reset of the gauge it tells me "no starboard engine detected" I did just recapped the boat and may have pulled a wire loose, but damn I checked and rechecked multiple times everything looks good

You're dealing with a digital system.

The fact that you have nothing means that you have issues with the pcm or gateway module.

Check to make sure you have power to the harness then unplug and reseat the main and gateway connectors.

Would hurt to put a bit of dielectric grease in the connections when reseating

I'm almost certain I dont have a gateway module as I'm running the smartcraft gauges and there's nothing plugged into the empty port on the junction box. Isn't that where the gateway would plug into?

 

[Scott Danforth]

The gateway is between the sensors and the gauges. In this case, most likely the ECM

No. A gateway is typically connected directly to the CAN connector on the motor if required. The junction box is just a breakout point for multiple gauge /sensor applications.

This may be of some help while troubleshooting

I can't seem to find where it's hooked into the motor, when you say the CAN connector is that where the resistor is near the ECU? That has a yellow cap on it now at the motor and my 14 pin is in the other lead. For what it's worth, my trim gauge doesn't work either. Everything worked until I swapped some batteries out and moved some wires under the dash to replace a rocker switch. I did have to kinda pull the panel out a bit in order to get to the switch, but from what I see there should have been nothing Can P related there. Also the previous owner said that his charts never showed gauges since he's owned it (10 yrs) so I'm thinking this was unhooked earlier.

The 14 pin connector is your CAN connection

That has a yellow cap on it now at the motor

More than likely that is where the NMEA 2000 Gateway would be plugged in to communicate with a Chart plotter, etc.

A digital system is constantly monitoring the various components for activity. Only take one component and or connection failure to shut you down.
Make sure the termination resistors are all in the proper location and seated
Are all network drop connections (items H-K) on the 14 pin harness tight?

Reading back through your original post, I note that you removed a terminator and plugged something in it's place. You can't to that. There are very specific locations where the terminators need to be in the system for it to operate.

Termination resistors are CAN line signal conditioners. The resistor places a known load on the CAN line to ensure proper system communication. All CAN bus termination resistors are 120 Ohms. Each CAN bus has two termination resistors installed, one at each of the furthest ends of the bus' running length. Resistance between the two data communication wires of the CAN bus should be approximately 60 Ohms. An incorrect number of termination resistors causes CAN bus communication errors.

Also the previous owner said that his charts never showed gauges since he's owned it (10 yrs) so I'm thinking this was unhooked earlier.

Need a NMEA 2000 Gateway to support that feature

I just purchased a new 14 pin motor to helm harness and hooked it to my motor and then to my ignition, kill switch and gauge...Same results... No starboard engine located... the new harness had the 120 ohm resistor near the end of the run (2 wire) and I made certain there was a yellow resistor on my engine harness.

Also when I say I removed the terminator plug that was to install a vessel view mobile module, which also did no communicate with the ECU. The motor starts and runs fine

Did you check to make sure you have roughly 60 ohms on the comm lines?

I had 115.8 ohms of resistance checking at the restore connector at the helm.. blue and white wire

Do you have a junction box ? Are we talking about smartcraft gauges, monitor or vessel view screen ? A gateway is not required for anything other than having a readout on a chart plotter or the vessel view screen units.
Make sure you have a yellow terminator in any spare or unused ports or plugs. Check the 10 pin plug that comes out the remote throttle control too. Tell me what exact unit we are dealing with. Sounds like you might be referring to something like sc1000 gauges and a VVM unit ?

There is a jct box which I replaced. The system is a SC1000 tack and speedo. I was not get data to those, I then plugged in my vessel view mobile module to the motor harness and it too would not read data. Terminators are in place and I even went as far as replacing the 14 pin harness from the motor to the dash. No luck. I ran continuity tests on the blue and white wires from the PCM harness to the 14 pin & diagnostic connector with good continuity. Basically no breaks in the wiring so I sent the PCM out to Simon Performance and they found a problem in the smartcraft circuitry, replaced a part or two and its on my way back... I sure hope this is it as it cost me close to $800 with shipping (2 day) IF it fixes the problem, what do you think could have toasted the circuitry?

It’s very possible that something like a short inside the remote control box, may have carried through the harness from the remotes up to the gauges. Can I be so cheeky to ask if the tacho and Speedo both have their correct dedicated loom plugged into them ? Easy to mix them both up and the plugs fit one another…but there is a very strong warning around absolutely making certain they aren’t mixed up the wrong way round.
I also know that if the master gauge (usually tachometer) has an issue…the Speedo slave unit can get lost.

I never unplugged both gauges at the same time. Always unplugged one connection, cleaned with contact cleaner, and reconnected. By hooking up my vessel view mobile module to the engine harness I figured that this is taking both gauges out of the equation. Also installed a new wire harness from 14 pin to helm and plugged only my tack into it.. Still no worky.. Like mentioned Simon Perf got the ECM and repaired it so we shall see on Tuesday when its scheduled to arrive.. By the way, what is the engine remote you speak of?

No worries. The remotes was meaning the throttle and gear control unit up at the helm. Never sure what to call it on here. I’m from Scotland and normally call it the throttle probably…but aware that might be known as the remote control box in the us?
Sounds like you might hopefully have a solution perhaps.
All I’d say though (had a few beers though..I’ll admit and could be wrong)…is that I’m sure that on my 2016 engjne, there is a separate port to plug in some of the smart craft gear. Mine is a port down under the coil packs. I’ve an analogue to digital conversion module in there somewhere too. That allows the functionality of things like digital trim display on the sc1000 gauges…water pressure etc etc too.
Did you try plugging the VesselView mobile into one of the ports on the junction box ? Just out of interest ? Do you have anything plugged into the link port on the tachometer or Speedo loom port ? Like voltage or fuel gauge ?

 

[QBhoy]

Meant to also ask…what’s the vf monitor ? Sorry to even ask this…but can I also ask that the terminator cap you used was obviously the yellow one ? Some engines come with a purple cap..looks similar but isn’t a terminator and won’t work. You’ll know all this, I’m sure.
Came to mind there too…but sometimes or maybe even anytime, when there has been a reset done or anything messed with..you need to make sure that the gauges are set up to know which is the master gauge. Then also in the case of having only one engine…that it definitely shows as much in the menu, that it’s set up for single engine and known as (starboard engine). Anyway. Likely all not relevant and hopefully your issue has been dealt with since. My tachometer gauge was replaced under warranty a few years ago. Stopped working or the screen lcd did at least.

 

[QBhoy]

Just to elaborate more on the mention of making sure it’s set to “starboard engjne”. You need to make sure it’s set to that on the gauge and on the engine ecu or pcm too.
Just came to mind there that you may have had a short circuit in that harness somewhere or at the remotes (like I was saying earlier). This could have caused a jolt back to delicate items. Meaning the dealer has to reset it and reconfigure it as “starboard engine”. Needs a diagnostic kit to do this on the pcm.
Going back to the remotes and harness. I don’t suppose you have one of the remote throttle units that there was a recall on ? There was an issue with them in the years around yours…where the power trim wires running up the handle get pinched and end up shorting out causing often quite serious issues. See below

VF = Vesselview mobile module that gets plugged into the engine harness and relays data to your smartphone through bluetooth. That could not find the engine eithera nd it's a simple plug and play. My terminator caps are yellow. Also I did a master reset on my tach gauge (master) and it went into auto detect for the engine and found nothing. Basically everything pointed towards the ECM. Especially after I placed a brand new engine to helm harness into the system with the same negative results. Something bit the PCM in the ass, just not sure what and that has me a little nervous about simply installing it on the engine and plugging it back in.

Got you. Yeah. I have a VVM too. Great things.
Did you see the bit about having to reset the ecu to configure starboard engine. Sometimes needs done by the sealer if there has been and Interruption
