matthew_129 Posted November 1, 2023 Report Share Posted November 1, 2023 Hi All, I have a Link G5 Voodoo and a Link MXG Strata and i am unable to get any information to pass over the can bus to the dash and not sure where to even start troubleshooting this as I think ive covered everything so far. On the can bus are the following -G5 Voodoo (Termination Enabled) -CAN Keypad 12 -Razor PDM -Blink Marine PG8 -Link MXG Strada (Termination Enabled) The G5, PDM, Keypad and PG8 are all communicating happily back and forth without any issue. However im unable to get the MXG to display any data, I have created a new layout and loaded it into the dash with just ECT and Voltage showing as I figured those values should pass quite happily to the dash. Dont think its of any relevance but the engine is currently not running but have most of the sensors hooked up so far. Screenshots and photo of dash below, any ideas?

Adamw Posted November 1, 2023 Report Share Posted November 1, 2023 All your settings look ok. Can you unplug the 14pin plug from the back of the dash and measure what voltage you have between pins 2 & 8 (gnd & CAN H) and also between pins 2 & 9 (gnd & CAN L). If there is data reaching the dash you should have >3V on pin 8 and <2V on pin 9. Quote Link to comment Share on other sites More sharing options...
matthew_129 Posted November 1, 2023 Author Report Share Posted November 1, 2023 Just checked and I'm showing 2.6v on pin 8 and 2.4v on pin 9, so I'm guessing something isn't right there? Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 1, 2023 Report Share Posted November 1, 2023 Those voltages at least suggest it is connected to a CAN bus, but I would have expected a bigger voltage difference if there were the 4 streams transmitting on that bus. Is it possible the dash is actually wired to CAN 2, not CAN 1? Quote Link to comment Share on other sites More sharing options...
matthew_129 Posted November 1, 2023 Author Report Share Posted November 1, 2023 No chance of being on CAN2, am coming off the 6 pin CAN1 connector with a CANLTW cable on the G5 through a handful of link CANTEE Y splits Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 1, 2023 Report Share Posted November 1, 2023 Do you have the same voltages if you check at one of the other devices? Can you attach a copy of the tune. Quote Link to comment Share on other sites More sharing options...
matthew_129 Posted November 1, 2023 Author Report Share Posted November 1, 2023 I will check the voltage at the other devices tonight when i get home, but copy of the tune is attached. Its fairly empty as it hasnt run yet, just getting the last few sensors connected APQ665 G5 Voodoo.pcl5 Quote Link to comment Share on other sites More sharing options...
matthew_129 Posted November 2, 2023 Author Report Share Posted November 2, 2023 Ive taken measurements at other places around the can bus and showing the same voltages all through. I also grabed a few photos of the very limited scope function on the power probe while looking at the can pins and there is defiantly some data there Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 2, 2023 Report Share Posted November 2, 2023 I just loaded your map into a G5 on the bench here, running the same firmware as yours, and had a good look at the broadcast data. The dash stream is there and all looks correct. With no other explanation that really fits your symptoms, Im leaning towards there being an issue with the dash now. One thing I would try is changing the ecu stream in the dash to something completely different, then change it back to the LINK CAN BUS BASE so it reinitialises the CAN set up. If still no go after that then I think the dash is going to have to come back for testing. Quote Link to comment Share on other sites More sharing options...
matthew_129 Posted November 6, 2023 Author Report Share Posted November 6, 2023 Just tried that this evening and no change, whats the go with sending this off to be looked at? Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 6, 2023 Report Share Posted November 6, 2023 Email [email protected], you can point them to this thread if you like to show troubleshooting that has been done already and they will advise options. Quote Link to comment Share on other sites More sharing options...
Electredge Posted November 15, 2023 Report Share Posted November 15, 2023 if you haven't figured this out yet, I've seen similar issues when CAN hi and CAN lo is wired backwards to the dash Quote Link to comment Share on other sites More sharing options...
