ECM REPROGRAMMING FOR P0133 - HEATED O2 SENSOR (FRONT) CIRCUIT SLOW RESPONSE

TECHNICAL SERVICE BULLETIN

Reference Number(s): TSB-10-13-005, Date of Issue: June, 2010

MITSUBISHI:

2009 Lancer

PURPOSE

On some affected vehicles, DTC P0133 may set in the ECM after driving on a road with a long, slow descent at a steady speed, with little or no change in the accelerator pedal position. The O2 sensor may respond slowly under these conditions and the PCM incorrectly judges the slow signal is due to a deteriorated O2 sensor.

This TSB describes ECM reprogramming procedures to correct this condition.

AFFECTED VEHICLES

2009 Lancer with 2.0L engine

REQUIRED OPERATIONS

The following equipment is needed to reprogram the ECM.

VCI (Vehicle Communication Interface) - MB991824.
Laptop computer with A/C power adaptor - 520924, or MIT547708.
MUT-III main harness 'A' (blue connector at the DLC end) - MB991910.
USB 2.0 cable - MB991827.
"Engine Compartment/Control Module" labels - p/n MSSF024G00.
MEDIC-II Download at M367 or higher.
For Standalone MUT-III units, reprogramming CD 06/10

If an affected vehicle has a Malfunction Indicator Lamp (MIL) illuminated and DTCs other than described above are listed in the ECM memory (before reprogramming), follow diagnostic instructions for the applicable DTCs per the service manual information. Do not reprogram the ECM until the reason for other DTCs being set is corrected.

REPAIR PROCEDURE

Check the underside of the hood to verify there is no Authorized Modification label previously installed to indicate this reprogramming has already been done. If a label is present and the "ROM ID #" on the label matches the "New S/W Part No." in the table on page 1 of this bulletin, the ECM is at the latest level and reprogramming is not necessary.
For MEDIC II users only: (MUT-III users go to step 5)
Verify the MEDIC-II is at version 5.6 and at download M367 or higher.
If your MEDIC-II Download is at least M367 , continue with the Reprogramming Procedure on page 4.

If your MEDIC-II Download is below M367 , update your MEDIC-II as follows.

Fig 1: Display Screen - MEDIC-II DOWNLOAD
On the MEDIC-II main screen, click on "Maintenance".

Fig 2: Display Screen - Maintenance
Click on "Download". After the download completes, click on "Cancel" to exit the "Maintenance" window. GO TO THE REPROGRAMMING PROCEDURE ON PAGE 4.

Scan Tool Viewer (STV) ONLY (MEDIC-II USERS go to the Programming Procedure on page 4). Verify that your MUT-III has the most current version of the reprogramming database:
1. From the MUT-III Main Page, select "Special Function", then select "ECU Reprogramming."
2. Select "Database File Display (CAN)."
  
  Fig 4: Display Screen - "ECU Reprogramming."
3. The database version is displayed in the top right corner of the screen. Make sure the database version is N10061 or greater.
  1. If the database version is N10061 or greater , reprogram the ECM as described in the Programming Procedure beginning on page 4.
  2. If the database version is less than N10061 , you must transfer the new reprogramming data from the Reflash Update CD 06/10 to the MUT-III hard drive as follows:
    
    Fig 5: Display Screen - Database Version
4. Return to the MUT-III main page by clicking the home icon in the lower left corner of the screen.
5. Install Reflash Update CD 06/10 into the PC's DVD-ROM drive.
6. Select Special Function
7. Select ECU Reprogramming.
8. A screen will appear advising "Installation Check An old database file exists or there is no database file. Please update to a new database file." Click the check mark in the pop up to continue.
9. Remove the Reflash Update CD from the PC's DVD-ROM drive and continue to the Reprogramming Procedure below.

REPROGRAMMING PROCEDURE

CONNECT A BATTERY CHARGER TO THE VEHICLE'S BATTERY DURING THE REPROGRAMMING PROCEDURE. DO NOT ALLOW THE BATTERY CHARGER TO TIME OUT. BATTERY VOLTAGE (AS MEASURED AT THE BATTERY POSTS WITHOUT ELECTRICAL LOAD) MUST BE KEPT AT 12.4V OR HIGHER IN ORDER TO REPROGRAM THE ECM. MEASURE THE BATTERY VOLTAGE AND CHARGE AS NECESSARY.

NOTE: VCI Stand-alone reprogramming is not available for this procedure. The laptop and the VCI must remain connected for the entire procedure.

Connect the equipment as follows:

Turn the laptop computer on. If you're running on battery power and the charge indicator in the lower right hand corner of the screen does not show a full charge, it is recommended that either the laptop battery be charged prior to beginning, or that reprogramming be completed with the A/C power adaptor connected to the laptop.
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.
