3406e check engine light problem

i have a 1994 western star 4964 heritage with a 475hp cat 3406e engine the other day i started the truck to pull out of the dock where i was getting unloaded and the check engine and stop engine lights came on and the check engine blinking i check the oil and anti freeze neither were low they were both good. when the lights are on the truck don't seem to act or run any different....what could be causing the lights to come on?

 

the code that its reading is 62

 

i checked the coolant and it is fine maybe the code needs to be reset?

 

alright will do i will have the code reset and then if that don't fix it i will see if it needs a new censor
