2015 Tahoe LTZ instrument cluster ground location?

[BlaineBug]

Just the codes relating to tire pressure, side traffic sensors. Dealer tested and all are fine. Initially all cluster gauges are wacky, turn signal not working, break light is still on, and gear light on cluster does not show the right gear. Car still runs fine and cluster if OK after 2-3 minutes.

Just for the heck of it, if the side sensors aren't working, unplug them and see if the issue returns.

Thanks. It's at the dealer now. I'll have them check that.

I mean I posted that in this thread as the solution to disconnect suspect modules. You need a dealer to pull a connector off a module you can reach in 2 min?

Just disconnect the passenger side module as it’s the master and the driver is the slave. Only the driver coms on the CANBUS.

It's spitballing but who the heck knows with the way the network can get corrupted from a bad module or sensor these days.
