Is there a way to display the last computer codes on a 2006 H2 without having to attach a special diagnostic tool to the vehicle?

I used to have a Jeep Grand Cherokee that would display the codes in the odometer after a certain ignition-key-turn combination.

Thanks!

 

I would be happy to look into this for you. In order to do more research, I will need the last eight of you VIN. Please feel free to contact me privately as well. Thank you.
