Hi Guys,
Got about 4000 km on my Jeep and last night the check engine light came on.
It actually was the first time I got the car startor to work, and when I got in I noticed the light on.
Also my ECO light doesn't come on anymore either.
Called the dealership but service is closed until January 4th.

Anyone else experience this?

 

Gone!!
Tightened the gas cap, I think that's what made the light go away.
Didn't show any code, just ------------.

Will check the fuel mileage and see if that changed.

 

Anytime I see a code I always check the gas cap first, especially if I was recently at a full service gas station. If that doesn't work I disconnect the battery for 5 minutes. If the check engine light comes back on within a few minutes of driving then I know I have to make a trip to the dealer.
