Check Engine Light
Hello! I changed my battery today--after installing the new battery, all is good except now the check engine light is on...has anyone had this issue? Any ideas? Thanks for your thoughts!!

I agree on ensuring the small black wire is securely attached. Otherwise strange issues can occur.

Check for DTC's, make a note if any.
Reboot the system.
Remove the neg battery cable, press on brake and hold fo 2 minutes, reconnect cable, allow time for all electronics to come up, reindex windows.
Recheck for codes.

BTW, there are 2 wires connected to the neg terminal, on short one and one long one...I noticed that on some of the utube vids I watched, they didn't have both
of those wires...do you have 2 wires connected to the neg terminal??

And, get a cheapo code-reader/resetter at any parts store. You'll likely need it at some point, on something, even if not now. Mine's an old Altel, as best I recall being away from home right now.
