Anyone familiar with that dtc?
“Ignition Switch Run/Start Position Circuit Low.”

2009 Yukon 5.3
remand starter
fresh battery
charging 14 +
ignition switch was replaced over 1 year ago, probably standard ignition products brand

vehicle starts easy, though occasionally starter stays engaged after engine running. It has a new starter solenoid.
while scanning it today with my hand held, it also displayed "PO69? clutch switch". this vehicle is an automatic from factory and with no modifications.

I've read fuse boxes are known to corrode on these GMs. I'm in Arkansas so corrosion is less of a concern but still possible.
