Pcm Reprogramming For VSS Malfunction - Emissions Recall Campaign (EMR-05-002)

PCM REPROGRAMMING FOR VSS MALFUNCTION - EMISSIONS RECALL CAMPAIGN

SERVICE CAMPAIGN BULLETIN

PURPOSE

Certain affected vehicles have incorrect parameters in the PCM software that may allow a malfunction in the vehicle speed sensor to go undetected by the On-board Diagnostic System (OBD). A faulty vehicle speed sensor, if undetected, could allow the vehicle to release pollutants in excess of emissions standards. Dealers must reprogram the PCM as described in this bulletin. Affected vehicles that are not reprogrammed may fail an Inspection/Maintenance (I/M) Smog Test.

AFFECTED VEHICLES

2005 Lancer and Outlander models equipped with 2.4L SOHC engine and manual transmission built between 6/22/04 - 6/30/05 (approximately 2,000 vehicles)

CUSTOMER NOTIFICATION

A letter will be sent to all owners of affected vehicles, telling them to bring their vehicle to a Mitsubishi Motors dealer to have the PCM reprogrammed at no charge. A copy of the customer notification letter appears later in this bulletin.

REQUIRED OPERATIONS

Before starting this campaign procedure, CHECK ON THE WARRANTY SUPERSCREEN  to verify that the vehicle is an affected VIN for this campaign and that this campaign procedure has not already been completed.

The following reprogramming equipment is required for this reprogramming:

• MUT-III / STV Reflash Update CD 10/05  or later
• MUT-III Reprogramming Adapter Harness MB991855 (for Outlander only)
• Memory Card 128 MByte Compact Flash MB991853
• Memory Card Adapter PCMCIA MB991939
• "Engine Compartment/Control Module" Labels p/n MSSF-024G-00

1. Check the underside of the hood to verify that there is no label previously installed to indicate that this Emissions Recall reprogramming has already been done.
2. Verify that the vehicle's PCM part number is listed in the table in Step  9 of this bulletin.
   1. Verify whether the ROM ID is the same as the ROM ID listed in the table in Step  9. If the ROM ID is the same as or higher than the ROM ID in the table, the PCM has already been reprogrammed for this concern.
3. Note any DTCs set in the PCM. Then use the MUT-III to erase all DTCs.
4. 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 N05091 or greater  .
   3. If the database version is less than N05091, go to Step 5.
   4. If the database version is N05091 or greater, go to Step  9.
5. Turn the ignition key to OFF and disconnect the MUT-III  .

6. Install Reflash Update CD 10/05  in the MUT-III laptop. Follow the CD installation instructions.
7. Transfer the reprogramming data from the laptop to the memory card. (Use the port on the left side of the MUT-III laptop.) Select ECU Reprogramming  , then Memory Card Transfer  . A status bar will display while the data is loading into the memory card.
8. When the memory card data transfer is complete, remove the memory card from the laptop and install it in the VCI. Connect the VCI to the vehicle, using the RED CABLE  . Be sure to connect both the 12-pin and 16-pin connectors securely  . (On Outlander models, adapter harness MB991855 is required.) YOU MUST DISCONNECT THE MUT-III LAPTOP  .
9. Reprogram the PCM, using VCI automatic reprogramming. It will take up to 20 minutes to complete the reprogramming.
   NOTE: If the message "ECU at Current Level of VCI" appears, the PCM did not reprogram. Verify that the ROM ID is the same as the ROM ID listed in the table below.

   • If the ROM ID is the same as or higher than the ROM ID in the table, the PCM has been reprogrammed for this concern.
   • If it is not, verify that the correct database update is in the MUT-III and was transferred to the memory card, and that the memory card is properly installed in the VCI.
   CAUTION: DO NOT DISTURB THE HARNESS CABLES OR CONNECTIONS. INTERRUPTION DURING THE PROGRAMMING PROCESS COULD CAUSE THE PCM TO LOSE DATA OR PREVENT FUTURE PCM REPROGRAMMING.
   1. After reprogramming is completed, the new ENG ROM ID and new A/T ROM ID will display alternately with the message "Turn IG SW OFF" every four seconds. Note this information.

   Verify the new PCM part number and ROM IDs are the same as those listed below:

10. Using a ball-point pen, enter the appropriate PCM part number, vendor number, ROM ID#, this recall bulletin number (EMR-05-002  ), your dealer code, and the current date on the Engine Compartment / Control Module Label (p/n MSSF-024G-00).

11. Carefully remove all dirt and oil from a vacant area near the VECI label on the underside of the hood, and affix the Engine Compartment label.
12. Affix the Control Module label to the PCM.
