PURPOSE
This reflash is to correct a communication error that may occur between the One-Touch
Start System (OSS) and Engine Control Unit (ECU) or the Keyless Operating System (KOS) and
Engine Control Unit (ECU), resulting in a no start of the engine.
1. When pressing the One-Touch Start System button (OSS), the engine will not start and a
warning message "immobilizer system service required" will appear on the multi information
display with the following DTCs:
B2417 - OSS authenticate error OSS
B1139 - KOS authenticate timeout
B1136 - Stop light switch
This TSB instructs dealers to conduct the following repairs within the warranty period, or on a
customer complaint basis to:
1. When "both the B2417 and B1139 DTCs" or all three B2417, B1139, and B1136 DTCs" are
detected;ʲreprogram the software of the OSS-ECU with the countermeasure software.
2. When DTC "B1157"* is detected along with B2417, B1139, and B1136; replace the OSS-ECUʲ
with a new one in accordance with the workshop manual.
*Check the software version of the new OSS-ECU and if it is not the latest version,
reprogram the OSS-ECU with the countermeasure software.
NOTE: If the software of the new ECU is the latest version, no need to reprogram the
software.
AFFECTED VEHICLES
2011 - 2021 Outlander Sport / RVR (equipped with OSS / KOS)
NOTE: The software was modified December 18, 2020 and the VIN cut off: JA4APVAU8MU014266.
IMPORTANT
To maximize customer satisfaction with the quality of their vehicle, affected new or used inventory vehicles should
be remedied before the vehicle is delivered. Dealers must check their inventory vehicles' VINs on the Warranty
Superscreen to verify whether the vehicle is involved in this service bulletin.

REPAIR PROCEDURE
• Confirm your MUT-III SE is updated with the latest reprogramming database.
• Write down all of 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, diagnose and repair those DTCs per
the service manual before reprogramming. DO NOT reprogram the ECU until the reason(s) for
other DTCs being set has been corrected.
EQUIPMENT
The following equipment is needed to reprogram the ECU:
•
•
•
•
•
•
VCI (Vehicle Communication Interface) or VCI Lite - MB991824 or MB992744
MEDIC Laptop/Tablet with A/C power adapter - 520924, or FZG1MK2.
MUT III Main Harness "A" (blue connector at the DLC end) - MB991910 or MB992745.
USB 2.0 Cable - MB991827 or MB992747.
MEDIC 3.5/4 update at 681 or higher.
For Standalone MUT III units, MUT3-SE Reprogramming Database N201201 or higher.

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 Engine ECU is at the latest level, reprogramming is not necessary.
NOTE: Reprogramming the Engine ECU with the latest database (e.g., N201201) includes all past
and current reprogramming for TSBs of affected vehicles. It is not necessary to reprogram the
ECU for each previous TSB.
For MEDIC 3.5/4 users only: (MUT-III SE STV users go to
step 5)
2. Verify the MEDIC 3.5/4 is at version 3.5 and at update
681 or higher.
If your MEDIC 3.5/4 update is at least 681,
continue with the Reprogramming Procedure. If
your MEDIC 3.5/4 update is below 681, update
your MEDIC as follows.

MUT3-SE
lower than N201201,, then the MUT3-SE
database needs to be updated. Once
database number is confirmed, hit the
