Recall - PCM Reprograming for VSS/OBD Concerns
No: EMR-05-002
DATE: October 10, 2005
MODEL: 2005 Lancer, Outlander
SUBJECT:
PCM REPROGRAMMING FOR VSS MALFUNCTION - EMISSIONS RECALL CAMPAIGN
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 Onboard
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.

already been done.
2. Verify that the vehicle's PCM part number is listed in the table in Step 9 of this bulletin.
a.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:
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
