I just installed a new system in my car, 4 diamond audio d6 6.5 compontes powered by a diamond d5 300.4 amp and a 10" diamond D9 sub powered by a diamond 600.2 amp. After driving my car for about 30 min after the install my service engine light came on. Is this just a coincidence or did my install trigger the light?

 

It's happened before - some just ignore it for a few days and it goes away. Others unplug the battery for ten minutes and get the same result.

 

+1 Be patient! It will go away within a couple of days.
