No: TSB-07-13-007DATE: July, 2007
MODEL:
2007 Outlander
SUBJECT:
ENGINE CONTROL MODULE REPROGRAMMING FOR THROTTLE HESITATION
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 below to assist in determining if a vehicle requires reprogramming. Then refer to the attachments for information on software part numbers for confirmation of to which level the control unit is programmed.
AFFECTED VEHICLES
2007 Outlander. See chart for specific vehicle production dates.
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 M160 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.
1. Check the underside of the hood to verify that there is no label previously installed to indicate that this reprogramming has already been done.
2. Verify the MEDIC II/ MUT III/STV version and download numbers.
For MEDIC II users only: (MUT III users go to step 3)
a. Verify that the MEDIC II is at version 4.0A and at download M160 or higher.
If your MEDIC II Down-load is below M160, update your MEDIC II as follows.
b. On the MEDIC II main screen click on "Maintenance".
C. Click on "Download". After the download completes click on "Cancel" to exit the "Maintenance" window.
GO TO THE REPROGRAMMING PROCEDURE.
3. Scan Tool Viewer (STV) ONLY (MEDIC-II USERS go to the Programming Procedure). Verify that your MUT-III has the most current version of the reprogramming database:
a. Select "Special Function" then select "ECU Reprogramming."
b. 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.
c. If the database version is N07061 or greater, reprogram the PCM as described in the Programming Procedure.
d. 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 08107 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.
