SAE - 61446 - Root cause not known SPN 61446 and 61448 are both undocumented codes. The only place I saw 61448 is in the SAE J1939 list and here is what I found.
Hydraulic Intake Pressure
Hydraulic Discharge Pressure Set Point
There is a manual for under 25 in PDF that has the full list of codes but there will still be some undocumented codes as well. Here is the link. What symptoms are you having with this truck?
Hi, Did you get this resolved?
