My 08' PSD broke down for 1 HOUR yesterday! The diplay showed Stop Safely Now! I have the Edge with Attitude 70hp chip installed (on level 1)and it showed regen was on and the EGTs were more than 1350f. I called the dealer with the code that it gave me. They said that it showed EGTs of more than 1500f and that it will not start for 1 hour. Later when the truck restarted the EGTs would stay very high. I would have to give it throttle and then let off, so it would cool down. When regen quit, No Problem.
