Newbie 2019 S-Mode not working, tried everything

ZoomZ

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.
