Question about pulling Check Engine Light codes?
I did some searching on here but couldn't find what i was looking for.
Is it possible to read check engine light codes with the car not running? I would guess that it is. My car won't start, and when I turn the key to the 'on' position (not to crank the motor, just to power up the electric) all the dash lights come on and then turn off, but the CEL stays lit. I read somewhere that the CEL is supposed to go unlit after a couple seconds., but mine does not.
So, can I hook up my battery, turn the ignition to 'on' and then pull the codes, if any, with a scan tool or at the local Autozone or Advanced Auto?
