REPAIR PROCEDURE
•
•
•
•
•
•
Confirm your MUT-III SE is updated with the latest reprogramming database.
Write down all the electrical device settings such as A/C and radio before reprogramming.
The settings should be restored after reprogramming.
Turn off all electrical devices to minimize the vehicle's electrical load. Also use an external
power source to ensure that the vehicle battery maintains the specified voltage during
reprogramming.
Make sure the USB cable and MUT-III SE main harness are not damaged.
Connect the MUT-III SE to an AC power source to prevent internal battery discharge.
Stay away from the under hood area during reprogramming. If the connection between
the Engine ECU and ETACS is lost, the cooling fan operates as fail-safe.
NOTE: If an affected vehicle has a Malfunction Indicator Lamp (MIL) illuminated before
reprogramming, and DTCs are listed in the ECU memory, save the ALL-DTC results and
then erase the codes prior to reprogramming. If hard codes are present that are
applicable to the target ECU and won’t clear, diagnose and repair these codes first and
then proceed with reprogramming.

REPAIR PROCEDURE
SOFTWARE/MEDIC VERSION VERIFICATION
1.
Verify that the ECU has not already been updated to the latest S/W number in the table above.
If the IPDM ECU is at the latest level, reprogramming is not necessary.
NOTE: Reprogramming the target ECU with the latest database (e.g., N230701)
includes all past and current reprogramming for TSBs of affected vehicles. It is not
necessary to reprogram the ECU for each previous TSB.

(5332/TSL2306016A)
For MEDIC 3.5/4 users only: (MUT-III SE users go to step 5)
2. Verify the MEDIC 3.5/4 is at version 3.5 and at update 808 or higher.
If your MEDIC 3.5/4 update is at least 808, continue with the Reprogramming Procedure. If
your MEDIC 3.5/4 update is below 808, update your MEDIC as follows.
3. Select the MEDIC 3.5/4 Admin tab and click on “Updates”.
4. If the MEDIC update screen advises updates are available, click the “Begin” button.
After all updates are complete, GO TO THE REPROGRAMMING PROCEDURE.

5. Click “STV”.
a. Confirm the vehicle information is accurate and click the ECU reprogramming button.
b. Click “ECU Reprogramming (SDB) and press the OK button”.
c. Confirm that the database number displayed is N230701 or higher.
i. If the database number displayed on your MUT3-SE is N230701 or greater,
continue to the next section.
ii. If the reprogramming database number displayed on your MUT3-SE is lower
than N230701, then the MUT3-SE database needs to be updated.
d. Once the database number
is confirmed, hit the Home
button to go back to the
System Select screen.

REPROGRAMMING PROCEDURE
To ensure that the vehicle battery maintains 12V during the procedure,
hook- up a battery charger to the vehicle during the procedure.
NOTE: VCI Stand−alone reprogramming is not available for this procedure. The laptop/tablet
and the VCI must remain connected for the entire procedure.
1. Connect the equipment as follows:
NOTE: VCI Lite and MEDIC 4.0 Toughpad shown for illustration purposes only.
Data Link
Connector (Blue
End)
MUT−III SE
Main Harness
•
Turn the MEDIC PC/tablet on. If the battery
indicator in the lower right hand corner of the
screen does not show a full charge, it is
recommended that either the battery be
charged prior to beginning or be used with the
A/C power adaptor connected.
•
Connect the USB cable to the VCI/VCI Lite. When
the laptop/tablet displays the MUT-III SE main
screen, connect the USB cable to the device.
Connect the MUT-III SE main harness with the
blue DLC connection to the VCI/VCI Lite. Connect
the blue connection of the MUT-III SE main
harness to the vehicle's data link connector.
•
USB Cable
Toughpad
(back)
VCI Lite
•
For VCI only (p/n MB991824): Turn the VCI
power switch ON. Verify that the indicator
lamp in the upper right corner of the screen is
green.
DO NOT DISTURB THE HARNESS CABLES OR CONNECTIONS DURING THE REPROGRAMMING PROCESS
AS IT COULD CAUSE THE CONTROL UNIT TO LOSE DATA. IF THE USB CABLE IS DISCONNECTED
DURING THIS PROCEDURE, A WARNING MESSAGE WILL DISPLAY.
NOTE: Due to limited space it may be easiest to connect cable onto negative ground post
and ground strap as shown below.
2. Turn the ignition switch to the “ON”
position.

3. Using MEDIC, from the main page, click the
“MUT3-SE” icon at the top center of
the screen.
4. The System Select screen opens and
populates with some basic information
from the vehicle. Look at the label on the
passenger side B pillar to identify the
appropriate class. (See B pillar label below;
class is labeled as “model”). If necessary,
select the correct class from the drop-down
list.
