Newbie 2019 S-Mode not working, tried everything

photoguy007

Unfortunately it wasn’t. I removed the switch from the console, and activated it unmounted, clicked fine, still no go.

Such a mystery!

Thanks

Well, dealer says it’s the cluster. It’s a Canadian vehicle. Was the cluster damaged upon the conversion from KM to Miles somehow?

Of course, Nissan won’t cover it, or even supply the U.S. dealer with the Canadian part number. They won’t allow a U.S. or Canadian cluster to be installed, WTF!

The dealer isn’t recommending I install a U.S. cluster, they believe it will be an electrical issue. Does anyone have insight regarding this?

Honestly, I’m not sure I agree with the assessment, have no idea though, I do like this service department. I’m only out $160 for diagnosis, if I’m going with a new cluster, it’s an easy diy, but would need the correct miles programmed.

I just want Rev matching working, probably won’t use very much, but want my car functioning properly.

Thanks for help!

Update

Don’t believe the cluster in my Z is the original one. It appears to be a U.S. cluster, believe it was swapped in. MPH are in large white numbers, not KM/H. Plus, there’s an old inventory sticker attached to it, probably from a recycled yard. My car is only 3 years old, shouldn’t have an old faded sticker anywhere. There’s no signs of this being any sort of salvaged car, body and interior are flawless, no signs of bodywork. Only feature not working is the Rev Matching. I’ve already road tripped it, drives perfectly! They probably swapped with U.S. cluster after taking in inventory.

So maybe it’s the cluster after all?

I was always insisting on wiring issue. Not sure if they actually dug into it per the FSM I posted for you.

Its a switch! Power, ground and signal to ecm. If cluster is bad, it's not the actual cause. Its just not providing one of those 3 things. In other words, shouldn't matter if Canadian or US cluster.

Its just dial markings. Everything else is just signal. Does ECM care how fast you going...YES. Does it care if you are doing KMH or MPH? Don't know, but it's just a conversion so both the same really.

second this
i can't think of any reason they would use different canbus ids across regions.

If the N is flashing it then it probably just needs a neutral position relearn and you can definitely do that by yourself, no need to give it to some stupid techs at the stealerships.

From FSM:

"SYSTEM DESCRIPTION
Refer to Owner's Manual for SynchroRev Match mode (S-MODE) operating instructions.
SynchroRev Match mode (S-MODE) controls engine speed at a suitable level from the present to the next
gear position. This control is switched by S-MODE switch (Refer to EC-531, "
Description"). When clutch pedal
is depressed and shift lever is shifted while S-MODE is being operated, gear position signal is sent to ECM.
ECM calculates target engine speed by gear position signal and vehicle speed signal, and then controls throttle
opening angle and ignition
timing. When downshift
is performed,
even if
accelerator
pedal is not depressed,
ECM
automatically controls throttle
opening angle and
increases engine
speed. When upshift
is
performed,
ECM
controls engine speed so
that it does
not drop lower
than the necessary level that is required
after
upshifting.
Engine
speed is controlled
according
to shifting
operation above
and
driver can perform shifting
operation
quickly,
smoothly,
and without shifting
shock.
When S-MODE
malfunction is
detected, S-MODE
warning
on information display illuminates
and S-MODE is automatically
cancelled.
At this
time, S-MODE indicator
turns OFF."

The signal from combination meter vehicle speed to ECM is via CAN BUS and subsequently, s-mode shift position indicator to combination meter is also CAN BUS.

If there is a short on the CAN BUS, you will have other failures. You do not show any of that. (ie: Tachometer not working or shift position indicator blank)

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.

N isn’t flashing.

It’s not the original cluster, but appears to be a sport one. My gear shows on the cluster, but the “S” window is blank. Maybe this is actually an A/T cluster? When I had the cluster out, I checked the pins, visually all seemed okay, didn’t notice any bent, missing, or rusty ones. But, I wouldn’t doubt it could be a crappy cluster they swapped in. I worked many years in the auto industry before my career, I know how things can go wrong.

Here’s the official diagnosis (below). I also discovered “Useable Auto Parts” in Canada. They specialize in recycled Nissan and Infinity parts, kinda lucked out there. I’m just going to purchase the appropriate cluster, they have a low miles one for $250. If the appropriate cluster is indeed the issue, no major issue, I’m only out a few bucks. Plus, I actually would like a KM/H cluster.

I’ll keep everyone updated, once my cluster gets here, will probably be a week or two going through customs. Extremely grateful for all the help from everyone!!! Thank you!!!

I hope it gets it fixed for you. It must be very frustrating.

As I mentioned earlier, seems like they did good troubleshooting for $160.

ZoomZ

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.

photoguy007

They even discounted the $160 a little. Synthetic oil change and diagnosis for $200, I do actually like their service department, total opposite of the previous dealer disaster.

Any updates mate?

Yes, dealers are hit and miss, the care of your car in their property is never #1 priority.
