Engine Controls - No Start/Hard Start Condition: Overview
No: TSB-08-13-004DATE: April, 2008
MODEL: 2008-09 Lancer
SUBJECT:
ECM REPROGRAMMING FOR NO START OR HARD TO START
PURPOSE
Customers of some affected vehicles may complain that the engine cranks for a long time but does not start. Some customers may state that the vehicle will start if they then depress the accelerator pedal slightly while cranking. The condition is due to an incorrect parameter in the ECM that closes the Electronic Throttle Valve (ETV) during start-up and doesn't allow sufficient air flow.
This TSB advises technicians to reprogram the ECM with new software to correct the parameters controlling the ETV.
AFFECTED VEHICLE(S)
2008 Lancer
2009 Lancer as per the chart shown above.
REQUIRED OPERATIONS
OVERVIEW
This procedure covers the following operations:
1. Reprogram the ECM with new software parameters.
2. Check for ALL DTCs. If DTCs are recorded in memory, diagnose and repair per the service manual.
The following equipment is needed to reprogram the PCM.
^ VCI (Vehicle Communication Interface) - MB991824
^ MEDIC-II Laptop computer - 520924, 528535, or 547708
^ 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-00SSF-024G-00
^ MEDIC-II Download at M207 or higher.
NOTE:
The software for this reflash is the same as the software for TSB-08-13-005 which modifies the software to change the rate that engine speed returns to idle. THE ECM WILL NOT ALLOW YOU TO REPROGRAM WITH THE SAME "NEW S/W PART #" A SECOND TIME. If there is a reprogramming label on the underside of the hood and the ROM ID on the label matches the New Software No. listed in the chart shown above, then the vehicle's software is to the latest specification and no reflash need be performed.
PRELIMINARY STEPS
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.
For MEDIC II users only: (MUT III/STV users go to step 5)
2. Verify that the MEDIC-II is at version 4.5A and at download M207 or higher.
If your MEDIC-II Down-load is below M207, 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 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 N08030 or greater.
c. If the database version is N08030 or greater, reprogram the PCM as described in the Programming Procedure.
d. If the database version is less than N08030, you must transfer the new reprogramming data from the Reflash Update CD 03/08 to the MUT-III hard drive as follows:
1. Install Reflash Update CD 03/08 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.
