Wife's Caravan threw a SES light today.  Does an 05 G. Caravan have a trick to read the codes through the dash?  For example, my Ram will tell the codes on the odometer display after a key-on,off,on,off,on cycle.   
I can have it scanned tomorrow, but wanted to know what code it has before I send her out in 6 degree weather tomorrow morning.   
Google turned up nothing...
