Repair Procedure

REPAIR PROCEDURE

1. Check the underside of the hood to verify there is no 'Authorized Modification" label previously installed to indicate this reprogramming has already been completed. If a label is present and the "ROM ID #" on the label matches the "New S/W Part No." in the table on page 1 of this bulletin, the ECM is at the latest level and reprogramming is not necessary.

For MEDIC II users only: (MUT-III users go to step 5)





2. Verify the MEDIC-II is at version 5.6 and at download M402 or higher.

If your MEDIC-II download is at least M402 continue with the "Reprogramming Procedure" shown in this bulletin.

If your MEDIC-II download is below M402, update your MEDIC-II as follows.





3. On the MEDIC-II main screen, click on "Maintenance".





4. Click on "Download". After the download completes, click on "Cancel" to exit the "Maintenance" window. GO TO THE "REPROGRAMMING PROCEDURE".

5. Scan Tool Viewer (STV) ONLY (MEDIC-II USERS go to the Procedure). Verify that your MUT-III has the most current version of the reprogramming database:





a. From the MUT-III Main Page, select "Special Function", then select "ECU Reprogramming."





b. Select "Database File Display (CAN)."

c. The database version is displayed in the top right corner of the screen. Make sure the database version is N10102 or greater.

1. If the database version is N10102 or greater, reprogram the ECM as described in the "Reprogramming Procedure".

2. If the database version is less than N10102, you must transfer the new reprogramming data from the Reflash Update CD 11/10 to the MUT-III hard drive as follows:

d. Return to the MUT-III main page by clicking the home icon in the lower left corner of the screen.

e. Install Reflash Update CD 11/10 into the PC's DVD-ROM drive.
