NOt to say the cluster ( Combination meter) cannot be faulty.

I just read the very first post where you say you got a $1500 discount in lieu for the meter replacement.

Sounds like you got the wrecker special, full of water and probably internal corrosion or bent pins etc.

You also say you have a sport model. I think someone stole your cluster and replaced with non-sport or one without rev matching pin-outs.

They didn't even bother to check the markings for the country.

I'm guessing this last dealer may have done the proper T/S to determine your wires are ok. Hence the diagnosis of bad Combo meter.

But what puzzles me is, this dealer should have realized what pin-outs are on the back of combo meter that supports the Harness in your car.

non sport dash doesn't have a gear position indicator.
and the trans does not send gear position can messages
iirc

seems like:
gear position works
wheel speed works

if you have a flashing n when you press the button then the switch works
but sounds like you have no flashing N
the switch is new (possible it came broken, don't rule that out)
or the switches wiring is messed up.

Time to get out a multimeter. and test those wires.

Here’s the diagnosis.

Thanks a ton!!

I could not find anything in the FSM that differentiated Sport from Non-sport. Only that the Mexico version had a different colour wire in the harness to Combination meter. (for one of the wires)

Not surprising that Nissan would leave gear Position indicator out for non-sport.

I'm a late model Nismo and not familiar with internal features of other models.

I would be very interested to see if the "window" for gear position is still installed, just not lit up. Oh Nissan.
