PURPOSE
Some affected vehicles may display an illuminated MIL with DTC P0420: Warm Up Catalyst Efficiency
Below Threshold, recorded in the ECM. An incorrect parameter in the judgment criteria may cause a false
MIL (mis−detection of a fault when an abnormal condition is not present).
This TSB provides dealers with a procedure to reprogram the ECM with new software to correct the
condition.
AFFECTED VEHICLES
2008−2010 Outlander w/4B12 2.4L, CVT, 2WD/4WD
2009−2010 Lancer w/4B12 2.4L, CVT or M/T
2010 Lancer Sportback w/4B12 2.4L, CVT or M/T
2010 models: Applies to FEDERAL Emissions vehicles only.
REQUIRED OPERATIONS
IMPORTANT: If an affected vehicle has a Malfunction Indicator Lamp (MIL) illuminated before
reprogramming and DTCs other than those described above are listed in the ECM memory, diagnose and
repair those DTCs per the service manual before reprogramming. DO NOT reprogram the ECM until the
reason(s) for other DTCs being set is corrected.
OVERVIEW
1. Confirm MUT−III software contains the latest reprogramming database
2. Reprogram the ECM with new software per the Reprogramming Procedure.
3. Perform “Erase and Read All DTCs.”
4. Perform a test drive to confirm DTCs do not return.

The following equipment is needed to reprogram the ECM.
D
MEDIC laptop computer with A/C power adaptor − 520924, or MIT547708.

REPAIR PROCEDURE
NOTE: Reprogramming the ECM with the latest database (i.e.12091) includes all past and current
reprogramming for TSBs of affected vehicles. You do not need to reprogram the ECM for each
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 ECM
Reprogramming Chart above, the ECM is at the latest level and reprogramming is not necessary.
Conduct normal diagnosis for the subject DTCs.
For MEDIC 3 users only: (MUT−III users go to step 5)
2. Verify the MEDIC 3 is at version 3.1 and at update 155
or higher.
If your MEDIC 3 update is at least 155, continue with
the Reprogramming Procedure on page 4.

Update
numbers
If your MEDIC 3 update is below 155, update your
MEDIC 3 as follows.

5. STANDALONE MUT−III SCAN TOOL VIEWER (STV)
ONLY:
(MEDIC 3 USERS GO TO THE
REPROGRAMMING PROCEDURE ON PAGE 4).
Verify that your MUT−III has the most current version
of the reprogramming database:
a. From the MUT−III Main Page:
D
Select “Special Function”
D
Select “ECU Reprogramming”
D
Select “Database File Display−CAN”
D
Confirm the database number displayed at the
top right of the chart is N12091 or higher.
(1) If the database number displayed on your
MUT−III is N12091 or higher, continue to the
Reprogramming Procedure on page 4.
(2) If the database number displayed on your
MUT−III is lower than N12091, locate the
Yellow MUT−III Reflash CD 02/12 and follow
the instructions on the CD label to update your
MUT−III.

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
VCI must remain connected for the entire procedure.
Connect the equipment as follows:
USB CABLE
VCI − LAPTOP
MEDIC−II / MUT−III
MAIN HARNESS
BLUE END
VCI
MEDIC 3 / MUT−III LAPTOP
D
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.
D
Connect the USB cable to the VCI.
D
When the laptop displays the MUT−III main screen, connect the USB cable to the laptop.
D
Connect the MUT−III main harness with the blue DLC connection to the VCI.
D
Connect the blue connector of the MUT−III main harness to the vehicle’s data link connector.
D
Turn the VCI power switch ON. Verify that the indicator lamp in the upper right corner of the screen
is green.
CAUTION
DO NOT DISTURB THE HARNESS CABLES OR CONNECTIONS.
INTERRUPTION DURING THE REPROGRAMMING PROCESS COULD CAUSE
THE CONTROL UNIT TO LOSE DATA OR PREVENT FUTURE
REPROGRAMMING. IF THE USB CABLE IS DISCONNECTED DURING THIS
PROCEDURE, A WARNING MESSAGE WILL DISPLAY.
