I have a check engine light on but no ECM codes, just BCM codes, wondering if anyone can point me in right direction with these shots of my Autel screen. Thank you.

I just went thru that. Everything worked but it would not start. Lights worked, dash lit up normally and i thought i was going to have to get a new starter because it just clicked or something like that. And i had that check engine light on too.

I checked the battery and it was like 11.8 volts. So, I went out and bought a new battery....problem solved!

It had power for all the lights and stuff, but not to turn the engine over.

I had the problem on and off for several years on a Dodge Magnum 5.7L R/T till year before last. No one could find it, the car ran fine. Finally turned out that I still had the original battery from 2005. Once I replaced the battery, never popped up again - sold the car last Fall.
