Default 12iS w/G3X FADEC Issue

Looking for some help troubleshooting why my G3X is not seeing the 912iS FADEC. I have no engine instruments - red Xs through all. When I go into Configuration Mode and select SYSTEM INFO, the FADEC line item has no green check or any info. There are no lane faults and no blown fuses in the cockpit as far as I can tell.

Support had me check continuity on CAN LO and CAN HI between the EMS and HIC and there was no issue there.

I really hope this is something obvious, even if I look dumb for it.

Any ideas are greatly appreciated.

(I am still pre-first engine start and I have never seen the engine gauges work. Until now I thought maybe the engine had to be running first.)

Both lane lights come on and then go out after a few seconds as expected.

Bobby,

What G3X Touch software version are you using? That is always the first thing to tell us in a report like this.

Sometimes people build a plane and try to power-up and use software that is many years old and lacking many of the newer features.

The current software is V9.01.

There are LED Status lights on the GEA 24; my install manual Rev. AN lists them in section 36.1.1 the troubleshooting section, a place to start.

The GEA 24 LED is flashing green, which the manual says is "On and communicating using the CAN Bus."

Since the CAN BUS is communicating, you won't need this CAN BUS troubleshooting guide:
