hi my name is ***** ***** is your engine full model and serial number? ISX15? etc?
CODE REASON EFFECT
Fault Code: 3712PID: P105SPN: 5246FMI: 0LAMP: RedSRT:
Aftertreatment SCR Operator Inducement - Data Valid But Above Normal Operating Range - Most Severe Level. Critical SCR related fault codes have been active for an extended period of time and require immediate attention.
Immediate engine power derate. Vehicle speed will be limited to 8 km [5 miles] per hour.
Your ECM has derated engine power due to an existing fault
The codes definitions tell you what circuit has the fault. Your aftertreatment circuit has a fault and regen is not possible. This will need to be corrected before full power will be restored by the ECM
So you already know what these codes mean and what circuits the faults indicate there are problems? So you do not want me to look them up? unfortunately you can not bypass this. The ECm would have to be reset and the fault is still there so the engine will derate again

After treatment Diesel Exhaust Fluid Dosing
Unit Input Lines - Condition Exists. The
after treatment diesel exhaust fluid dosing
unit is unable to prime.
Have the driver check the DEF fluid level and for restrictions or leaks....
Engine Protection Torque Derate - Condition
Exists. Critical fault codes related to engine
operation are active.

There is a restriction or leak or possible faulty def pump not picking up the DEF.
Yes. Either plugged lines, Leaks, or pump problem not picking up the DEF
sometimes the DEF Doser is plugged..... In some cases a manual/parked regen may cure the problem
Same procedure and principle. Click here
I know I did. I wrote same procedure and principle.
There is a test in Cummins Insite DEF Reductant Doser Prime Override Test / DEF Reductant Doser Pump Override Test Where the DEF doser is disconnected and the pump can be tested for proper flow etc with Cummins Insite connected to initiate the test.
it is 12:16 EST here. We can follow up as needed but i am logging out for the night. Your options are look for a restriction or leak and repair if found and if no leaks check for Def pump flow or signs of return pressure that it is working. If not you will need Cummins Insite connected for further troubleshooting
Pleasure to help
