I have a 2002 Dodge Ram 2500 van with 110k miles, parked it in the driveway last night went to leave this morning wont crank, sounds like its going to start but doesn't, I'm getting a "NO Bus" indication on the OD panel, and error codes 920 921, and 999. I have looked at all wiring everything seems to be okay found no corrosion, any ideas ????

 

anybody????

 

anybody????

 

this is a 5.9gas eng??
the codes (p09xx) were read with a scanner? will this scanner also read manufacturer specific p1000+? OFTEN THERE IS some codes

they indicate transmission codes likely


anything below apply may give us a direction-
1)vehicle is stock no MODS OR aftermarket BS
B) no remote starter!!!
3) repairsor accidents?

if nothing applies start by cking PDC FUSE 1 GOOD TRANS RELAY ?

 

no aftermarket stuff, van is stock, no crashes, the codes were read off the OD display by holding the reset button for 10 seconds while turning the key on, where is the pcd trans relay fuse???

 

PDC under hood fuse and relay

if you can autozone - advance auto and others will scan for free the p09xx are trans codes....
