2010 Freightliner Cascadia - codes onguard errors

Here's what I have:
86325/9--timeout of CFG_E message
625/9--ACM PT-CAN DM1 Message Not Received or has Stopped Arriving
(I'm assuming you have a Detroit Powertrain...FYI post your powertrain info as well so I know which relevant fault codes pertain to your 2010 Cascadia.)

Recommendation:
It seems something is going on with your Engine CAN network--PTCAN in this case possibly. Your ATS module is one of the most crucial for operating your vehicle without the derate. I bet you probably have a stop engine light and can only go 5 mph max w/stop override.

 

Good. That is helpful information. Have you load tested your batteries? What condition are they in? Maybe your voltage rails to your ACM are not getting up to voltage to make the module turn on. I'm wondering if you have a power issue. The PDM is next to the steering column-- if that's what you mean. Located on the driver fender. Also your PNDB is on the firewall that's close to the steering linkage.. Should be a little red light next to it. Does it ever blink fast or anything like that when this problem happens? Now that I think about it, the circuit 439B that controls the ACM connects to the PNDB. Should be that 30 amp fuse. Possibly the fuse is cracked?

Inspect, and post what you find.

 

Okay...after looking at your truck, you don't have an ACM. You just have CPC and MCM that controls the aftertreatment.

 

So your DDECVI has the powertrain fuses on the PDM which circuit is 439B. 30 amp is for the MCM and 10 amp for the CPC. I'd check those out.

 

There you go!....you're welcome.

 

Quite possibly...
