Hello and welcome to just answer.i can help you with this..


0253-02 Check Customer or System Parameters (56)

SMCS - 1901-038

Conditions Which Generate This Code:

This condition indicates a customer specified parameter or a system configuration parameter that requires programming has not been programmed.

System Response:

When a new Engine Control Module (ECM) is initially powered up, the following parameters must be programmed in order to avoid this diagnostic code:

  • Full Load Setting (FLS)


  • Full Torque Setting (FTS)


  • Vehicle speed calibration


  • Rating number


  • Engine serial number


  • Injector trim files


Note: If the "Rating Number" has not been programmed, the ECM will limit the engine power to 119 kW (160 hp).

  • The ECM may limit the engine speed to low idle.


this is the code if the serial number on your engine starts with mbn,let me know how you do,this code can come up if the ecm is starting to act up..
