Freightliner shuts off while driving

good point. my lawn mower does the same stuff. the switch is bad and grounding it self out.

 

i cut the white wire. lawn mower wont cut off. i have to take air filter cover off and choke it down with a rag

 

Hello Mikem, what was the fix to your problem?, I have a 2010 Cascadia DD15 doing the exact thing: Fan kicks on; I lose fuel pressure; check engine lights up; plus low engine break and lose cruise control. Mechanics checked for wiring and one suggested is the connection between ECM and CPC however he could not get to it. Your input is appreciated.

 

You make alotta money and you spend alotta money! I replaced the harness(1,200.), and that didn't fix it at the local mechanic, so I took is to Detroit where it sits waiting to replace the CPC, and clean the MCM connector (1,800) estimate plus the down time. I just hope I don't ave to fork out the final 900 plus labor. thanks for the reply.

 

FYI: if any time you notice the voltage gauge shows > 14.2 volts that indicates the 5A fuse of the PNDB is busted. This fuse is to keep the voltage from the alternator to PNDB at 14.2 or less. There is a relay in the PNDB that cannot handle more than 14.2v. If the 5A fuse is busted the relay will eventually wear out and it will cause loss of power while driving and you’ll have to replace the whole PNDB which costs about $405+tax. But it’s so to prevent this by replacing the 5A fuse any time you see truck’s voltage more than 14.2. There are 2 latches holding the door, snap those off, take out the door and you’ll see 4 fuses, the brown top one is the 5A fuse and if it’s busted, replace it and you’ll see the voltage drops back to 14.0 or 14.1v.

 

What and where is the PNDB? I have 2000 FLD112 that just started doing this yesterday.

 

My cascadi has the same issue , i wonder if you got it fixed? And what was the problem ?
