AWC ECU REPROGRAMMING SERVICE CAMPAIGN

SERVICE CAMPAIGN BULLETIN

Reference Number(s): SC-11-002, Date of Issue: March 01, 2011

MITSUBISHI:

2008-2010 Lancer Evolution; 2009-2010 Lancer Ralliart; 2009-2010 Lancer Sportback Ralliart

Superceded Bulletin(s): SC-09-002, Date of Issue: September, 2009

REVISION HISTORY

NOTE: This bulletin supercedes SC-09-002, issued September, 2009, to update the ECU reprogramming software.

PURPOSE

This reprogramming procedure will modify the All-Wheel-Control (AWC) ECU software to accurately match the operations check of the AYC/ACD motor with current ambient conditions. Extremely cold weather causes increased excessive load on the motor, which could result in damage to the motor. This bulletin describes procedures to reprogram the AWC ECU with new software parameters to prevent this condition.

NOTE: This reprogramming may be performed on vehicles that have not had AWC warning lamp illumination.

REPAIR PROCEDURE

Check the underside of the hood to verify that there is no label previously installed to indicate that this campaign has already been done.
- If a label is present and the ROM ID# on the label matches the ROM ID# below, the ECU is already at the latest level. Reprogramming is not necessary. Do not continue with this bulletin.

For MEDIC 3 users only:

In the MEDIC 3 home screen under Updates, check the Update and Reflash Database numbers.
If your MEDIC 3 is not at Update 26 or higher and Reflash Database N11011 or higher, select Updates in the Admin screen to force a download, bringing your machine to the latest version of MEDIC 3.
Continue with the REPROGRAMMING PROCEDURE below.

For MEDIC II users only:

Verify that MEDIC II is at Download M409 or higher by checking the bottom of the screen.
If your MEDIC-II Download is below M409, update your MEDIC-II as follows:
On the MEDIC-II main screen, click on "Maintenance".
In the window pop-up screen, click on "Download".
After the download completes, click on "Cancel" to exit the "Maintenance" window.

Continue with the REPROGRAMMING PROCEDURE below.

Scan Tool Viewer (STV) ONLY: Verify that your MUT-III has the most current version of the reprogramming database:

Select "Special Function", then select "ECU Reprogramming."
Select "Database File Display (CAN)."
The database version is displayed in the top right corner of the screen. Make sure the database version is N11011 or greater.
If the database version is N11011 or greater , reprogram the AWC ECU as described in the REPROGRAMMING PROCEDURE below.
If the database version is less than N11011 , check to see that your MUT-III version is at 24 or higher.

If it is not at version 24 or higher, locate your MUT-III Scan Tool Viewer version 24 CD, and follow the instructions to update the laptop.

REPROGRAMMING PROCEDURE

BATTERY VOLTAGE (AS MEASURED AT THE BATTERY POSTS WITHOUT ELECTRICAL LOAD) MUST BE KEPT AT 12.4V OR HIGHER IN ORDER TO REPROGRAM THE ECM. MEASURE THE BATTERY VOLTAGE AND CHARGE AS NECESSARY. A BATTERY CHARGER SHOULD BE CONNECTED TO THE VEHICLE'S BATTERY DURING THE REPROGRAMMING PROCEDURE. DO NOT ALLOW THE BATTERY CHARGER TO TIME OUT.

NOTE: VCI Stand-alone reprogramming is not available for this procedure. The laptop and the VCI must remain connected for the entire procedure.

Connect the equipment as follows:

Turn the laptop computer on. If you're running on battery power and the charge indicator in the lower right hand corner of the screen does not show a full charge, it is recommended that either the laptop battery be charged prior to beginning, or that reprogramming be completed with the A/C power adaptor connected to the laptop.
Connect the USB cable to the VCI.
When the laptop displays the MUT-III main screen, connect the USB cable to the laptop.
Connect the MUT-III main harness with the blue DLC connection to the VCI.
Connect the blue connector of the MUT-III main harness to the vehicle's data link connector.
Turn the VCI power switch ON. Verify that the indicator lamp in the upper right corner of the screen is green.

CAUTION: DO NOT DISTURB THE HARNESS CABLES OR CONNECTIONS. INTERRUPTION DURING THE REPROGRAMMING PROCESS COULD CAUSE THE CONTROL UNIT TO LOSE DATA OR PREVENT FUTURE REPROGRAMMING. IF THE USB CABLE IS DISCONNECTED DURING THIS PROCEDURE, A WARNING MESSAGE WILL DISPLAY

AWC ECU Reprogramming Procedure

Conduct the following steps to reprogram the AWC ECU.

Turn the ignition key or knob (F.A.S.T. equipped) to the ON position. If the vehicle is equipped with the F.A.S.T. System, the fob must remain in the vehicle for the entire procedure.
In the MEDIC main page, click on MUT-III.
Select "Special Function."
Select "ECU reprogramming."
Select "Automatic Reprogramming (CAN)."
Click on the car icon at the bottom of the page.
If the VIN listed does not match the vehicle you are working on, click on the eraser icon at the bottom of the page.
Click on the VIN button.
Click on the icon in the lower RH corner of the screen to have the MUT-III automatically read the VIN. If a message appears saying that the VIN cannot be input automatically, manually type the 17 digit VIN into the VIN field.
Make sure the VIN is correct and click on the check mark.

A window may pop up asking you to select either the transmission type or vehicle class. Click the check mark to clear the window.

Click on either the TRANSMISSION or CLASS button and make the appropriate selection from the menu, Then click the check mark at the bottom of the page. Vehicle class can be found on the Vehicle Information Code Plate riveted to the base of the RH B-pillar (see photo below). The class is part of the model code.

Click the check mark to enter the class. Confirm that all of the data is correctly entered, then click the check mark at the bottom of the page.
Select 5. ACD or AYC/ACD
Then click on the check mark at the bottom of the page.
A message will advise you that the system will "Automatic search the data."
Click on the check mark to continue.

NOTE: If a "Complete Reprogramming" message is displayed, the ECM is already reprogrammed for this concern. If this message displays, do not continue with this reprogramming procedure. Click the check mark to clear the window, then click on the Home icon at the lower left corner of the screen to return to the System Select main page.

If a "Complete Reprogramming" message does not appear, continue with this procedure.
The CAN database screen will display.
Confirm the database number at the top right of the table is N11011 or higher.

If more than one row is displayed in the table, select the appropriate ECM part number.

Click on the check mark to continue.
Click on the check mark to begin reprogramming. It may take up to 5 minutes to complete the reprogramming.

CAUTION: The Daytime Running Lights and both the engine and condenser fans will automatically be turned on during reprogramming. Care should be taken to insure nothing gets caught in the moving blades. The radio will be turned off, instrument warning lights will illuminate and you will also hear a chime in the interior for a short period of time. These are normal conditions.
This message will display when the reprogramming is successfully completed. Record the S/W (Software) Part No. and compare it to the "New Software P/N' in the table below.
Turn the ignition key/knob to the OFF position, wait approximately 10 seconds, then turn it back on.
Click the check mark and you will be returned to the "ECU Reprogramming" page.

Click on the "Home" icon at the bottom left of the screen.
