2002 GMC Yukon Denali - SES light on after battery died
I had my ignition switch turned to the "ON" position this afternoon, and totally
forgot about it being on. After being on for a minimum of 2 hours, my battery had
all but died - Denali wouldn't crank, windows wouldn't come up, etc. So, I
connected a batter charger for about 5 minutes & got Denali to crank. HOWEVER,
the Service Engine Soon light is now on & I can't get it to turn off! I drove vehicle
around my subdivision, which is exactly 1 mile, but the light is still on. How can I
fix this?
