I just installed the infinity basslink into my car. I only messed with the battery and poking into the firewall. The next morning, when i took my car out, i noticed the check engine light on. ANy idea what the problem could be? Would the dealer check it for me even if he knew i was messing around there while installing sub? please help.

 

How many miles do you have on your car? Does the light stay on constantly or go out after a few seconds?

 

If the dealer is cool and they are concerned with customer satisfaction they wont *itch about anything. try turning the key to acc 4 times with out tunring the car on and check if the light still comes on if it does have a diagnostic check run. if its because u need an oil change go get it
