I'll start as you suggested, test power to the switch.

Just a couple last questions below, then I'll let you be for a couple of days (lol), til' I get back to this.

1. I was wondering, is there a specific connector for S-Mode to the cluster, or is it routed into a connector with other functions? Hope this makes sense.

2. If there is a connection issue to the cluster, would that affect the function of S-Mode, or does it just not display "S"? I ask this because, one issue I had with the cluster, the turn indicators were actually working outside, but didn't display on cluster. This was remedied when I replaced the shipping fuse.

3. Ironically (first thing I always do), I haven't checked fault codes. Just purchased the Z, and haven't ordered a system reader yet. Can you recommend one for around $200? Not a simple code reader, but something more involved, like my "iCarsoft" scanner for my truck.

I really appreciate all your help, this is extremely helpful! I'm actually excited and driven now, to figure this out, can't let it go!

Thank you!!

There are two fuses. 1 for combo meter ( Fuse #4 which you pulled) and another fuse for S-mode switch (fuse #3. both 10A)
Check #3.

There is a "signal" connection between Combo meter and S-mode switch. It should be one connector with specific pins.

4.CHECK S-MODE SWITCH INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect combination meter harness connector.
3. Check the continuity between S-MODE switch harness connector and combination meter harness con-
nector.
S-MODE switch Combination meter
Continuity
Connector Terminal Connector Terminal
M255 1 M53 12 Existed
4. Also check harness for short to ground and short to power.

So you want to check Connector 255, pin 1 at Switch to connector 53 at combo meter pin 12.

I highly doubt you have a short but there are "junction" connector (M98) along the way. Those could have not been connected or loose.

good luck.

oh and for OBDII, I use APP called "OBD Fusion" with A wifi dongle and ipad.

Many more out there, just google or youtube

[QUOTE=ZoomZ;4023383]There are two fuses. 1 for combo meter ( Fuse #4 which you pulled) and another fuse for S-mode switch (fuse #3. both 10A)
Check #3.

Just for fuse reference, the one circled is the one I replaced (Elec. Parts), you call #4, the natural order doesn't seem to be #4. Which would be #3/S-Mode fuse? The "Meter" fuse?

Just noticed the upside down fuses, on that right away!!

Thanks.

And no more questions for you today.

Unless you're just OCD there is no reason to change the fuses. Current is flowing through both sides of the fuse in the same direction, no matter the orientation of the fuse.

[QUOTE=photoguy007;4023390]a little different from the FSM but generally same. ( not accepting my image)

Looking at your fuse box image, left column, upper slot (empty) is #1. So #3 and #4 is electric parts and meter.

Hey guys, sorry to thread jack. I’m having the same issues with S-mode; it isn’t working. Upon initial start up the S will be displayed in the cluster, then after driving a few seconds it throws the warning on the cluster screen. Codes I’m getting are P2765 input turbine speed sensor circuit B. I’ve changed the sensor on the trans on the left hand side and no avail. For reference, my Z is single turbo and triple disc clutch with cmak. S mode was working perfectly even after the build, and only recently have I run into this issue. I’ve checked the mentioned fuses, all good. I took it to Nissan today, and their scanners couldn’t connect to my Z. Unsure if tuning could be the culprit. Idk if it’s a CAN communication issue, nor do I know where the CAN-BUS wires/connector is located to assess it. I’ve checked all connectors going to the transmission and all is well there too. I’m open to any ideas or advice as I’m truly out of ideas and Nissan was of no help unfortunately.

I might have an S mode button if yours is bad. I just hacked up a manual trim ring for my build.

[QUOTE=ZoomZ;4023430]Really appreciate all your help, I’m back on this.

1. I purchased a new switch, no change
2. Going to check the other end of the S-Mode harness tomorrow, I’m hoping it’s not connected!
3. I am hearing my clutch spinning when pedal is out, but just read this is normal?

Thanks

[QUOTE=photoguy007;4027669]Just and update to anyone interested. S-Mode still not functioning.
1.Today (and so far), I checked all connections (well believe I did)
2. Removed cluster to inspect if anything seemed odd, all good.
3. Replaced switch with brand new one
4. Checked clutch switch under pedal (my cruise works fine)
5. System reboot


I’ll attempt to check power going to switch, I’m little confused how to do, but will figure out

[QUOTE=photoguy007;4027717]Dropped off at dealer today, after a full day, they still haven’t figured out the issue.

[QUOTE=photoguy007;4028264]My S mode wasn't working when I got my car as well. I also noticed a few people saying there's no "click" to the button. Mine did not have any click to it either. That said, I ended up unscrewing the shift boot bezel which released the switch and I noticed I could get a clicking actuation out of the switch, indicating that my button was not getting enough travel and was always being pressed. I added a washer to the screw nearest the button which keeps the shifter bezel and the ring together. This ensured the additional button travel and actuation which has my S mode working even today.

Hope this helps.

Edit: I see OP bought a new switch so my thoughts may be null :/ hope the dealer figures it out.

[QUOTE=Iammeowwwwww;4028270]That's extremely interesting, I noticed I wasn't getting a click when installed, but would click uninstalled.

I'm just going to pick up my Z, they can't figure out the issue, I'm sure it's sitting on the sidelines anyhow.

Dealer couldn’t fix issue
 

The dealer couldn’t fix, they say it’s the switch, the switch is brand new. Plus now my hvac goes from cold to blistering hot in one click. So upon reassembly, they didn’t plug something back in. Now I have to drive all the way back again. Plus my shift knob wasn’t screwed on, and the leather is damaged, and my CD is gone from my head unit.

At this point I’m angry, very sloppy service! WTF!

This is why many despise the dealers!!
