ECM REPROGRAMMING FOR FALSE MIL ILLUMINATION WITH DTC P2097 - REVISED

ECM REPROGRAMMING FOR FALSE MIL ILLUMINATION WITH DTC P2097 - REVISED

TECHNICAL SERVICE BULLETIN

Reference Number(s): TSB-15-13-002, Date of Issue:  March, 2015
MITSUBISHI: 2011 - 2014 Lancer/Lancer Sportback, Outlander Sport/RVR; 2011 - 2013 Outlander
Superceded Bulletin(s): TSB-14-13-003, Date of Issue:  July, 2014

REVISION HISTORY

This bulletin supersedes TSB-14-13-003, issued July, 2014 to expand the Affected Vehicles to include additional models. For affected 2011 - 2013 models, linear air-fuel sensor (LAFS) replacement is required. Revisions are not indicated as this bulletin has been completely re-written.

PURPOSE

This TSB provides a field fix procedure to address false MIL illumination with DTC P2097 (Rear Oxygen Sensor Feedback Control System Monitoring) stored in the ECM. To minimize false MIL illumination, this software update optimizes the target A/F ratio adjustment condition when the accelerator pedal is depressed and released suddenly. For affected 2011 - 2013 models, the linear air-fuel sensor (LAFS) must also be replaced.

BACKGROUND

During rear oxygen sensor feedback control system monitoring, if the accelerator pedal is depressed and released suddenly, it may cause false MIL illumination due to an improper target A/F ratio adjustment setting.

AFFECTED VEHICLES

2011 - 2014 Lancer/Lancer Sportback equipped with 4B11 (2.0L) or 4B12 (2.4L) engine (non-turbo) - built before the end of May, 2014

2011 - 2013 Outlander equipped with 4B12 (2.4L) engine

2011 - 2014 Outlander Sport/RVR equipped with 4B11 (2.0L) engine

REQUIRED OPERATIONS

OVERVIEW

  1. Confirm your MUT-III is updated with the latest reprogramming database.
  2. For affected 2011 - 2013 models, replace the linear air-fuel sensor.
  3. Diagnose (and repair if necessary) the failure condition using the applicable service manual.
  4. Reprogram the ECM with the new software. Refer to the ECM REPROGRAMMING CHART  for new software information.
    IMPORTANT: If an affected vehicle has a Malfunction Indicator Lamp (MIL) illuminated before reprogramming  , and DTCs other than described above are listed in ECM memory, diagnose and repair those DTCs per the applicable service manual before reprogramming. DO NOT  reprogram the ECM until the reason(s) for other DTCs being set is corrected.

REPAIR PROCEDURE

NOTE: Reprogramming the ECM using the latest database (i.e. N15021) includes all past and current reprogramming for TSBs of affected vehicles. It is not necessary to reprogram the ECM for each previous TSB.
  1. Check the underside of the hood to verify there is no "Authorized Modification" label (see page 11 for example) previously installed to indicate this reprogramming has already been completed. If a label is present and the "ROM ID #" on the label matches the "New S/W Part No." in the table above, the ECM is at the latest level and reprogramming is not necessary. Conduct normal diagnosis for the described condition.
  2. If the affected vehicle is a 2011 - 2013 model, replace the linear air-fuel sensor. Refer to the applicable service manual, Group 15: Intake and Exhaust > Exhaust Pipe and Main Muffler (2.0L Engine Non-turbo, 2.4L Engine) > Removal and Installation. 
  3. Before beginning this reprogramming procedure, disconnect the negative (-) battery terminal for 60 seconds or more to erase the learned value. Then reconnect it. 

    For MEDIC 3/4 users only: (MUT-III users go to step   5 ) 

  4. Verify the MEDIC 3/4 is at version 3.2 and at update 321  or higher.

    If your MEDIC 3 update is at least 321  , continue with the REPROGRAMMING PROCEDURE  .

    If your MEDIC 3 update is below 321  , update your MEDIC 3/4 as follows.

    G09911082
  5. Select the MEDIC 3/4 Admin tab and click on "Updates."
    G09911083
  6. IF the MEDIC update screen advises updates are available, click the "Begin" button. After all updates are complete, GO TO THE REPROGRAMMING PROCEDURE  .
    G09911084
  7. STANDALONE MUT-III SCAN TOOL VIEWER (STV) ONLY: (MEDIC 3/4 USERS GO TO THE REPROGRAMMING PROCEDURE  ). Verify that your MUT-III has the most current version of the reprogramming database:
    1. From the MUT-III Main Page:
      • Select "Special Function"
      • Select "ECU Reprogramming"
      • Select: Database File Display-CAN"
      • Confirm the database number displayed at the top right of the chart is N15021 or higher 
        1. If the database number displayed on your MUT-III is N15021  or greater, continue to the REPROGRAMMING PROCEDURE  .
        2. If the reprogramming database number displayed on your MUT-III is lower than N15021,  locate the reprogramming CD containing database N15021  and follow the instructions provided with the CD to update your MUT-III.
          G09911085

REPROGRAMMING PROCEDURE

CAUTION: 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.
