3120RL none of tank sensors working

[mpd2001]

I have been searching but can not find any info. On my 2021 3120rl none of my tank guages are reading on my incommand. Is there a fuse for the tank sensors or is there a common hookup that would cause all 4 sensors to not read? I'm not sure where to start. Thanks

All tank signals come into the BCM as indicated with this pic I’ve attached .Simce all tanks are not reading you either have no inout signal from BCM to each tank sensor unit or you have a bad ground

Use your multimeter and you should be able to find the issue pretty quickly

Thanks Chuck, that's super helpful. Now I have a place to start. Thanks again
