I came accross something interesting while navigating my Coupe ESM. (I'm assuming the Sedan's is the same or similar.)
It's a way to diagnose and confirm the operation of all your gauges in front of you in the dash: Infiniti calls these 'Combination Meters' and consist of Speedo, Tach, Coolant temp, Fuel gauge, *including low fuel light*, the 2 trip meters & odometer and all their segments, and all the segments of the A/T indicator.
I'm converting from PDF to JPEG format and couldn't put both segments on one post. (there's P1 + P2)

A quick word of caution: go slow and read the instructions carefully. It took me a few tries to make it work properly, but it works. This is neat stuff......enjoy

Just because I feel like showing off a bit before crashing for the night, here's the single-ply version, in a shiny, tiny gif. [img]/w3timages/icons/smile.gif[/img]

And it does work on the sedan, too. I just tried it. Pretty cool.

this info would be great to have my fuel gauge is all loopy

 

Here’s how to put the gauge instrument into test mode:
