Technician: roybelding, Shop Foreman Freightliner trucks replied 2 years ago

OK, 1569 is the last or final warning for the truck in derate.

5246 is the key. I posted below the flow chart for the code.

Do you have the program to read the information on the truck? You will need that to clear the code when you get a complete regen.

1569 31

This fault code is for information only, and indicates that an engine power derate has been implemented in order to make sure that the critical fault codes that are presently active in the ECM are addressed as quickly as possible. There has to be other codes logged active or inactive in the ECM memory for this informational only code to be present. You need to have the ECM scanned and get me the inactive and active code numbers logged in history. At the same tim Insite is connected I would reflash and update the ECM after pulling your codes. Let me know what is logged in memory.

CODE REASON EFFECT

Fault Code: 3714
PID: S115
SPN: 1569
FMI: 31
LAMP: Amber
SRT:

Engine Protection Torque Derate - Condition Exists. Critical fault codes related to engine operation are active.

What fault code? Neither one you gave me indicates a knock sensor code.

You need the Insite program to clear the code.
