PURPOSE
This bulletin provides instructions for reprogramming the Telematics Control Unit (TCU) with new software.
This software will address communication malfunctions with Mitsubishi Connect in the following
situations:
D

When a vehicle moves out of the United States to another country such as Canada and Mexico,
and returns to the U.S., some functions of the Connected Car Service do not operate.

D

After a contract for Connected Car Service has expired, and a customer re-signs a contract, the
service cannot be used.

BACKGROUND
Possible causes for these malfunctions are:
D

After crossing a national border, the IP address is not switched correctly. The emergency warning
can be used, but the data communication is disabled, even after the vehicle returns back to the
U.S.

D

After a customer re-signs their contract, the Connected Car Service cannot be reactivated unless
the 12V battery has been disconnected and reconnected. This updates the status of data
communication.

AFFECTED VEHICLES
2018 Eclipse Cross vehicles equipped with Telematics Control Unit (TCU) / Mitsubishi Connect
produced BEFORE March 6, 2018.
NOTE: Affected vehicles can be identified on the Superscreen by the Description “Eclipse Cross Telematics
Re-Flash - See TSB-18-54-001” under “Open Vehicle Services.”
Vehicles with TCU /
Mitsubishi Connect

Identification of TCU-Equipped Vehicles:
To identify whether a vehicle is equipped with the
Telematics Control Unit (TCU) / Mitsubishi Connect:
Look for the “SOS” and “i” buttons in the dome light
area.

These vehicles have been marked with an 8 mm orange sticker on the Airbag Caution tag
attached to the right side of the glove box, in the approximate location shown below.
!! IMPORTANT !!

Vehicles with Reflashed TCU Have an Orange
Sticker on Airbag Caution Tag (approx. location)

1. Confirm your MUT-III is updated with the latest reprogramming database.
2. Reprogram the TCU with the new software. Refer to the TCU Reprogramming Chart for new software
information.
IMPORTANT: If an affected vehicle has a Malfunction Indicator Lamp (MIL) illuminated before
reprogramming, and DTCs are listed in the TCU memory, diagnose and repair those DTCs per the service
manual before reprogramming.
EQUIPMENT
The following equipment is needed to reprogram the TCU.
D VCI Lite - MB992744V.
D MEDIC Laptop/Tablet with A/C power adapter - MIT540031, or FZG1MK2.
D MUT-III main harness 'A' (blue connector at the DLC end) - MB992745V.

For MEDIC 3.5/4 users only: (MUT-III STV users go to
step 5)
2. Verify the MEDIC 3.5/4 is at version 3.5 and at update
513 or higher.
If your MEDIC 3.5/4 update is at least 513, continue
with the Reprogramming Procedure on page 4.

If the reprogramming database number
displayed on your MUT3-SE is lower than
N180201, then the MUT3-SE database
needs to be updated.

N180201

e. Once database number is confirmed, hit the Home
button to go back to the System Select screen.

PREPARATION
Before beginning the TCU software update, 2 fusible links (No. 19 and 23) should be removed during
the reprogramming process to avoid vehicle battery consumption.
NOTE: Removing these fusible links will also prevent the cooling fans from turning on during reprogramming.

1. Locate fuse box in engine compartment.
