ENGINE CONTROL MODULE REPROGRAMMING FOR THROTTLE HESITATION

TECHNICAL SERVICE BULLETIN

Reference Number(s): TSB-07-13-007, Date of Issue: July, 2007

MITSUBISHI:

2007 Outlander

PURPOSE

Affected vehicles have incorrect parameters in the Engine Control Module (ECM) software that may cause the feeling of a hesitation or throttle lag. The condition is mostly noticed when depressing the accelerator at slow speeds following a deceleration, as in accelerating after making a turn.

IMPORTANT: THIS REPROGRAMMING PROCEDURE MUST BE COMPLETED AT THE SAME TIME AS TSB 07-23-006 FOR REPROGRAMMING THE TRANSMISSION CONTROL MODULE. WHEN YOU HAVE COMPLETED THE STEPS FOR THIS REPROGRAMMING PROCEDURE, DO NOT DISCONNECT THE SCAN TOOL AND IMMEDIATELY BEGIN THE PROCEDURES FROM TSB 07-23-006.

Reprogram the ECM as described in this bulletin. See the chart under AFFECTED VEHICLES CHART below to assist in determining if a vehicle requires reprogramming. Then refer to the attachments on page 12 for information on software part numbers for confirmation of to which level the control unit is programmed.

AFFECTED VEHICLES

2007 Outlander. See chart below for specific vehicle production dates.

AFFECTED VEHICLES CHART

Control Unit	Specification	Built Prior to	First VIN (last 8)
ECM	FED 2WD	May 28, 2007	7Z021125
	CA 2WD	June 1, 2007	7Z021522
	FED 4WD	May 31, 2007	7Z021383
	CA 4WD	June 1, 2007	7Z021534
TCM	ALL	May 31, 2007	7Z021366

NOTE: ALL VEHICLES BUILT PRIOR TO MAY 28 REQUIRE REPROGRAMMING OF THE ECM.

ALL VEHICLES BUILT STARTING JUNE 1, 2007 WILL ALREADY BE PROGRAMMED TO THE LATEST SPECIFICATION. DO NOT REPROGRAM THESE VEHICLES.

REQUIRED OPERATIONS

The following equipment is needed to reprogram the ECM.

VCI (Vehicle Communication Interface) - MB991824
Laptop computer - 520924 or 528535
MUT-III main harness 'A' (blue connector at the DLC end) - MB991910
USB 2.0 cable - MB991827
"Engine Compartment/Control Module" labels - p/n MSSF-024G-00
MEDIC II Download at MM160 or higher.

If an affected vehicle has a Service Engine Soon (SES) lamp illuminated and DTCs listed in the ECM memory (before reprogramming), follow diagnostic instructions for the applicable DTCs per the service manual information. Do not reprogram either control module until the reason for DTCs being set is corrected.

Check the underside of the hood to verify that there is no label previously installed to indicate that this reprogramming has already been done.
For MEDIC II users only: (MUT III users go to step 5)
Verify that the MEDIC II is at version 4.0A and at download MM160 or higher.
If your MEDIC II Down-load is below MM160 , update your MEDIC II as follows.

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. Select "Special Function", then select "ECU Reprogramming."
2. Select "Database File Display." The database version is displayed in the top right corner of the screen. Make sure the database version is N07061 or greater.
3. If the database version is N07061 or greater, reprogram the PCM as described in the Programming Procedure .
4. If the database version is less than N07061 , you must transfer the new reprogramming data from the Reflash Update CD 08/07 to the MUT-III hard drive as follows:
  1. Install Reflash Update CD 08/07 into the PC's DVD-ROM drive.
  2. Follow the instructions on the screen. The system will automatically transfer the reprogramming data onto the PC's hard drive.
  3. Continue to the Reprogramming Procedure.

REPROGRAMMING PROCEDURE

CAUTION: 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 DURING THE REPRGRAMMING PROCEDURE. DO NOT ALLOW THE BATTERY CHARGER TO TIME OUT

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:

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.

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.

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.

ECM Reprogramming

Conduct the following steps to reprogram the ECM.
1. 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.
2. Select "Special Function."

  NOTE: If this screen does not appear, continue with step k.
  
  If the ECM is already reprogrammed for this concern, this screen will display. If this message displays, do not continue with this reprogramming procedure. Review the AFFECTED VEHICLES CHART and the charts in Attachment 1 of this TSB to determine if this vehicle may have been partially or completely updated. If the chart indicates that the TCM may still need updating, procede to TSB-07-23-006 to conduct TCM reprogramming.

  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.
  
  It is possible that the ECM has the latest software update, but the TCM may still be to the old specification and needs reprogramming. Ensure if the TCM has not been programmed, and continue with the steps on TSB-07-23-006 if necessary.
11. The CAN database screen will display.
  (If more than one row is displayed in the table, select the appropriate ECM part number.)
  
  Click on the check mark to continue.

  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 and you will also hear a chime in the interior for a short period of time. These are normal conditions.
13. This message will display when the ECM reprogramming is successfully completed. Record the S/W (Software) Part No. and compare it to the "New Part No." in the table in attachment 1 at the end of this TSB.

  Click the check mark and you will be returned to the "ECU Reprogramming" page.
  
  Refer to the the AFFECTED VEHICLES CHART and the charts in Attachment 1 of this TSB. If the TCM does not require reprogramming, continue with Step 2. If the TCM does require reprogramming, conduct reprogramming according to the steps on TSB-07-23-006 .
Turn the ignition key/knob to the OFF position, wait approximately 10 seconds, then turn it back on.
Using the MUT III, check and erase ALL DTCs from all systems as follows.
1. Select "Special Function."
