Got a weird issue.
Truck is a 2009 Sierra, Truck had dead batteries when it came into the shop, so I charged them up fully, Good voltage to the truck, Go to crank it, Nothing but clicks to the starter, BUT when I put a diagnostic relay in (dummy relay with a switch) truck cranks.
Throwing the following DTCs:
P0633
(I will post any other ones in a few when I go check the truck again.)
Truck has the xx8594 Cal in (actually flashed a new one from GM).
The Vats light is NOT lit up on the cluster. Just the TPMS light and MIL light.
Key is already learned according to the tech 2.
Has anyone seen this? I always seem to get the troubled children..:roflmao:
I have been lacking in my visits lately, I promise to visit more often , Shop has been busy and growing.
