The fuel pump and the engine cooling fan(s) may run during the following procedure. If you are programming a 6.0L diesel, the FICM relay must be removed before programming.
Set the ignition switch to ON (Connect SVCI J2534 tool and ECU module again)
It starts reprogramming PCM and will take about 4 minutes, please keep patient.
Then follow the prompt to set ignition switch to OFF…ON…OFF till it shows “Calibration has been loaded and checked”.
Note: If you programmed a 6.0L diesel, please reinstall the FICM relay.
If required, obtained a PCM reprogramming label and complete with the following data in the prompt. A reprogramming label is not required on vehicles serviced in North America.
Place the completed label in the appropriate position.
Then start engine, do not depress the throttle pedal!
Set ignition to OFF (position 0)…ON, and it starts clearing the fault codes
Finally set ignition switch to OFF
