Circuit low fault codes

freightliner ? anyways you can call a dealer most will tell you

 

Can I get a follow up on this thread? I have same 3 faults. Installed new ACM, aftertreatment harness and sensor harness for 1 box. Installed test ecm and same 3 faults 3609, 3509, and 3610 all fmi 4

 

Same here. Have been chasing 3610 fmi 2 for months. Have replaced Box 1, DPF, wiring harness, def lines, doser, etc. Anyone else have any ideas?

 

Have u fixed the problem? Having same issue

 

We thought we did. Replaced another sensor and everything was fine for about a week....the 3610 once again a couple days ago. Just replaced the inlet pressure sensor as it’s literally the only thing left of the old system....it is entirely new now....

Something tells me it’ll be back in the shop next week. We’ve lost 9 weeks of running so far....

 

Have u replace batteries?did inlet pressure sensor do the trick ?

 

Any luck ? Having same issue check engine light won’t go away. Tech wants me to swap batteries now.

 

We have replaced batteries recently actually. The inlet sensor seems to be helping but it took a couple weeks last time before it came on so fingers crossed but I’m not convinced just yet. I’ll update post after a month or so and some regens.
