Newbie 2019 S-Mode not working, tried everything

ZoomZ

Everything goes through the ECM. The combination meter also sends a signal via CAN bus to the ECM as well as the shift position indicator via CAN bus.

Since you had dash issues, look for a disconnected wire or connector.

Did they install an aftermarket ALARM system? (if I had a nickel for every F**ck up found after an alarm install.)

I cannot get a print out of the service manual. section EC-125.

Other sensors that send information for REv match to work:

-Crankshaft and CamShaft position sensors
Cluth pedal POSITION and Clutch Interlock switch
-Gear lever position sensor
-Input speed sensor
-Combination meter (via CAN bus)

Look under hood as well as under dash.

Just did:

1. Another ECU reset
2. Checked Upper Clutch Switch, position seems fine, it pushes the switch pin in (assuming this what it's supposed to do, when clutch pedal is not engaged)
3. Checked fuses, though I'm not sure which specific one to check
4. Checked S-Mode switch connection, wiggled a few items
5. The car looks new all over, all stock, only 2400 miles, only evidence of any fiddling around, is the cluster was removed for diagnosis.
6. There is no aftermarket alarm, but there is a device connected supposedly to fight rust corrosion (see pic).

Thank you for all of this info! I'll be back on it mid-week, working long shifts next three days.
