I've got a 00 Durango, and check engine light is on - I tried to do the on/off trick a few times, but I couldn't get the diag code to show on the odometer. I read that some mopars you hold down the trip button near the odometer and turn ignition on, but when I did that, it said "CHEC" on the odometer .. Then came the bad news, when I started the truck, the odometer, overhead display and radio will NOT power on :-/

 

problem solved - thanks for the 3 people that at least viewed the thread - but no more issue
