Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
PCM REPROGRAMMING:
1. Verify the customer concern.
2. Using the image above, verify the PCM is manufactured by Mitsubishi.
3. Reboot the IDS to clear memory before reprogramming.
4. Using IDS 113.01 or later software, reprogram the PCM to the latest calibration (refer to “Calibration
Information” table) by following the “Module Reprogramming” procedure.
NOTE:
• Always update the IDS tool first, then follow on-screen instructions to download the needed calibration file
for PCM reprogramming.
• Verify the current PCM file name in the vehicle by log view screen. If it's the same as shown in the chart
below (or a later one), you do not need to reprogram the PCM.
• It is not necessary to remove any fuses or relays during PCM reprogramming when the IDS screen
prompts you to do so. You may accidentally stop power to one of the PCM terminals and cause the PCM to
be blanked, or you may receive error messages during the IDS reprogramming procedure.
• IDS shows the calibration part numbers after programming the PCM.
• Please be aware that PCM calibration part numbers and file names listed in any Service Bulletin may
change due to future releases of IDS software, and additional revisions made to those calibrations for
service related concerns.
• When reprogramming a PCM, IDS will always display the “latest” calibration P/N available for that vehicle.
If any calibration has been revised/updated to contain new information for a new service concern/issue, it
will also contain all previously released calibrations.
• Start/Stop button vehicles: DO NOT press the start/stop button during the reprogramming process.
• When performing this procedure, we recommend using the “Power Supply” mode in the Battery
Management System to keep the vehicle battery up to capacity. If a different charger is used, make sure it
does not exceed 20 AMPS. If it exceeds 20 AMPS, it could damage the VCM.
• After the reprogramming, verify the file name matches with the below chart.
5. After performing the PCM reprogramming procedure, clear DTCs.
6. After clearing DTCs, start the engine and confirm that no warning lights stay on.
7. Record customer presets in the infotainment system.
8. Disconnect the negative battery cable and wait for 30 seconds or more to reset the fuel control learning
data.
9. Re-connect the negative battery cable.
10. Re-enter customer presets in infotainment system.
NOTE:
If any DTCs should remain after performing DTC erase, diagnose the DTCs using MGSS online instructions
and submit a warranty claim according to the normal warranty procedure.
