TCM REPROGRAMMING FOR SHIFT SHOCK AT COLD ENGINE TEMPERATURE

TCM REPROGRAMMING FOR SHIFT SHOCK AT COLD ENGINE TEMPERATURE

TECHNICAL SERVICE BULLETIN

Reference Number(s): TSB-10-23-006, Date of Issue:  September 2010
MITSUBISHI: 2009-10 Outlander
GROUP: 23 - Automatic Transaxle

PURPOSE

Customers of some affected vehicles may notice a shock when the transmission shifts from 1st to 2nd or downshifts from 3rd to 2nd, when the fluid temperature is below 10°C (50°F). This condition is due to transmission fluid line pressure being higher than expected at these temperatures.

This TSB describes procedures to reprogram the TCM with new parameters to correct the condition.

AFFECTED VEHICLES

2009-2010 Outlander V6 built prior to the following dates:

U.S & Puerto Rico: July 20, 2010

Canada: July 21, 2010

REQUIRED OPERATIONS

The following equipment is needed to reprogram the ECM. 

If an affected vehicle has a Malfunction Indicator Lamp (MIL) illuminated and DTCs other than described above are recorded in the TCM memory (before reprogramming), follow diagnostic instructions for the applicable DTCs per the service manual. Do not reprogram the TCM until the reason for other DTCs being set is corrected.

REPROGRAMMING 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 done. 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 TSB, the TCM 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 M384 or higher.

    If your MEDIC-II Download is at least M384,  continue with the REPROGRAMMING PROCEDURE .

    If your MEDIC-II Download is below M384  , update your MEDIC-II as follows.

    G06948378
  3. On the MEDIC-II main screen, click on "Maintenance".
    G06948379
  4. Click on "Download". After the download completes, click on "Cancel" to exit the "Maintenance" window. GO TO THE REPROGRAMMING PROCEDURE .
    G06948380
  5. Scan Tool Viewer (STV) ONLY (MEDIC-II USERS go to the REPROGRAMMING PROCEDURE ). Verify that your MUT-III has the most current version of the reprogramming database:
    1. From the MUT-III Main Page, select "Special Function", then select "ECU Reprogramming."
    2. Select "Database File Display (CAN)."
      G06948381
    3. The database version is displayed in the top right corner of the screen.
      1. If the database version is N10091 or greater  , reprogram the vehicle's ECM as described in the Programming Procedure  beginning on page 4.
      2. If the database version is less than N10091  , you must transfer the new reprogramming data from the Reflash Update CD 10/10  to the MUT-III hard drive as follows:
        G06948382
    4. Return to the MUT-III main page by clicking the home icon in the lower left corner of the screen.
    5. Install Reflash Update CD 10/10  into the PC's DVD-ROM drive.
    6. Select Special Function
    7. Select ECU Reprogramming.
    8. A screen will appear advising "Installation Check An old database file exists or there is no database file. Please update to a new database file." Click the check mark in the pop up to continue.
    9. Remove the Reflash Update CD from the PC's DVD-ROM drive and continue to the REPROGRAMMING PROCEDURE  below.
      G06948383

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 TCM. MEASURE THE BATTERY VOLTAGE AND CHARGE AS NECESSARY. DURING REPROGRAMMING, A BATTERY CHARGER SHOULD BE CONNECTED TO THE VEHICLE'S BATTERY. DO NOT ALLOW THE CHARGER TO TIME OUT DURING THE REPROGRAMMING PROCEDURE. 

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

Connect the equipment as follows: 

  1. Connect the USB cable to the VCI.
  2. When the laptop displays the MUT-III main screen, connect the USB cable to the laptop.
  3. Connect the MUT-III main harness with the blue DLC connection to the VCI.
  4. Connect the blue connector of the MUT-III main harness to the vehicle's data link connector.
  5. Turn the VCI power switch ON. Verify that the indicator lamp in the upper right corner of the screen is green.
    NOTE: If the USB cable is disconnected during this procedure, a warning message will display. Close the message display by clicking on the OK button and check USB connections.
    G06948384
    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.

TCM Reprogramming
