Engine light on with gascap on dashboard. Checked with flashcal.
Have two codes for right and left low beam circuit high.

Reset the codes and engine light went off.

Double checked the codes were the same after that, and then it had 4 codes. The same two and a evap leak small .020 and a high beam circuit high.

Reset those and it’s back to the two low beam codes.

So question is, with Kc led headlights those codes will just be there, as the light work just fine. Get the gascap word on dashboard fixed with silicone on gascap o ring and part that touches gas tunnel. Reset the codes to get rid of engine light and just know that with led light your going to have codes on there for that.

Just want no check engine light on, so I can get inspection stickers with ease.

Does this sound right for anyone who has had these things happen.

If the KC headlights are LED, it is possible they are throwing a code as they use less current than OEM halogens (if your Jeep was sold with halogens)...common with LED retrofits on a number of JKs. The TIPM detects something amiss when normal current levels are not drawn on the headlight circuit and generates an error.

Yea want to make sure. That is what it came with and have led KC. Good lights.

So I need to get silicone grease and do the gascap o ring and area. See if that takes care of engine light.
