Engine Control Module Programming and Setup W/RPO LMM

The following service procedures require either a programming or a setup event performed for a complete repair.

ECM Replacement

If the engine control module (ECM) is replaced, the following procedures must be performed:

  1. Capture the Option data.

    2. Important: Clear any DTCs that may have set after completing the programming procedure.

  2. Enable ECM Reprogramming--Refer to Service Programming System (SPS).
  3. Restore the Option data in the new ECM.
  4. Start and idle vehicle.
  5. Using the scan tool, perform the Turbocharger Learn Procedure. Refer to Turbocharger Learn.
  6. Perform a DPF Regeneration Enable. Refer to Diesel Particulate Filter (DPF) Regeneration Enable.
  7. If necessary, perform the following:
    8. • The Fuel Injector Flow Rate Programming--Refer to Fuel Injector Flow Rate Programming.
    • Engine Oil Life Remaining--Use scan tool to reset Engine Oil Life.
    • Fuel Filter Life--Use scan tool to reset Fuel Filter Life.

ECM Reprogramming

    Important: It is necessary to record Fuel Filter Life before reprogramming. The ECM reprogramming procedure will reset Fuel Filter Life to zero.

  1. Record Fuel Filter Life.

    2. Important: Clear any DTCs that may have set after completing the programming procedure.

  2. Enable ECM Reprogramming--Refer to Service Programming System (SPS).
  3. Reset Fuel Filter Life to the recorded value.
  4. Start and idle vehicle.
  5. Using the scan tool, perform the Turbocharger Learn Procedure. Refer to Turbocharger Learn.
  6. Perform a DPF Regeneration Enable. Refer to Exhaust Particulate Filter Cleaning.
  7. If necessary, perform the following:
    8. • Speed Calibration Programming--Refer to Speed Calibration Programming.
    • The Fuel Injector Flow Rate Programming--Refer to Fuel Injector Flow Rate Programming.
    • Engine Oil Life Remaining--Use scan tool to reset Engine Oil Life.

Setup for Component Replacement

The replacement of some components will require a setup procedure for complete repair.

If any of the following components are replaced, a Turbocharger Learn Procedure must be performed.

    • Turbocharger
    • Turbocharger Vane Position Sensor
    • Turbocharger Vane Position Control Solenoid Valve

Engine Control Module Programming and Setup W/RPO LF8

The following service procedures require either a programming or a setup event be performed for a complete repair.

ECM Replacement

If the engine control module (ECM) is replaced, the following procedures must be performed:

    • The ECM Reprogramming--Refer to Service Programming System (SPS).
    • The Fuel Injector Flow Rate Programming--Refer to Fuel Injector Flow Rate Programming.
    • The Option Programming--Refer to Option Programming.
    • The Speed Calibration Programming--Refer to Speed Calibration Programming.
    • The Turbocharger Learn Procedure--Refer to Turbocharger Learn.
    • Engine Oil Life Remaining--When available, use a scan tool to reset the Engine Oil Life Remaining back to the original percentage recorded before the module was reprogrammed.
    • Transmission Fluid Life Remaining--When available, use a scan tool to reset the Transmission Fluid Life Remaining back to the original percentage recorded before the module was reprogrammed.

ECM Reprogramming
    • If the ECM needs to be reprogrammed, refer to Service Programming System (SPS).
    • Engine Oil Life Remaining--When available, use a scan tool to reset the Engine Oil Life Remaining back to the original percentage recorded before the module was reprogrammed.
    • Transmission Fluid Life Remaining--When available, use a scan tool to reset the Transmission Fluid Life Remaining back to the original percentage recorded before the module was reprogrammed.

Setup for Component Replacement

The replacement of some components will require a setup procedure for complete repair.

If any of the following components are replaced, a Turbocharger Learn Procedure must be performed:

    • Turbocharger
    • Turbocharger vane position sensor
    • Turbocharger vane position control solenoid valve

If any of the following components are changed to a different specification, a Speed calibration Programming procedure must be performed:

    • Tires and wheel
    • Differential gears
    • Transmission

If any of the following components are replaced, a Fuel Injector Flow Rate Programming procedure must be performed:

    • A single fuel injector
    • Multiple fuel injectors
