Check engine on 2011 Jeep Grand Cherokee Laredo

It's been cold, but I had the block heater plugged in and when I started it up, the check engine light came on.

Is there any way to get the code without a scanner on the new Jeep Grand Cherokees?

That would be my instinct, however I'm about 3000km away from the dealer right now, in the Yukon...

I thought someone had mentioned you could still get the codes like the WKI, not sure of that process though. It is just an emissions function that has malfunctioned anyways, you will be fine to drive the car until you can make it to the dealer.

You could try this:
Retrieving codes (2005-2010 Grand Cherokee): Insert and turn the ignition key from "Off" to "On" three times, moderately fast and without pausing ("ON" is when the digital odometer displays):
Tip: use the "count to 5" method, where "1" is the first "On":
Off > On > Off > On > Off > On
0 1 2 3 4 5
0 - Insert key (Off)
1 - On
2 - Off
3 - On
4 - Off
5 - On
At the third "On" the odometer display will read "DTC REPORT" and list the codes. If no codes are present the message "Done" will appear.
It can take several times to get it right. Also, make sure to do this with the door closed.
