PURPOSE
This reprogramming of the ECU is to change the auxiliary battery charge stopping conditions under
low State of Charge (SOC) conditions of the drive battery when the vehicle turns off. Additionally, the
configuration update of the IPDM E/R and BCM increases the charging amount while reducing the
discharge amount from the auxiliary battery while the vehicle turns off.
On a customer complaint basis, please reprogram the PHEV-ECU with the latest one and update the
configuration (C/U setup) of IPDM E/R and BCM.
AFFECTED VEHICLES
2023-2024 Outlander Plug-in Hybrid, VIN Cut-off: JA4T5VA98RZ050396 (built prior to 2/8/2024)
REPAIR PROCEDURE
When battery capacity test is performed, please refer to (4) Electrical & Power Control section in
TSB-24-42-001 (Service Manual Revision) for information regarding removing battery cable before
voltage measurement.
CAUTION DURING 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.
The low voltage of the auxiliary battery may cause the incompletion of reprogramming and
once it happens, ECU must be replaced to brand new one.
⚫ Write down all the customer’s electrical device settings such as A/C and radio before
reprogramming and restore them after reprogramming.
⚫ Connect the MUT-3 to an AC power source to prevent internal battery discharge.
⚫ Before using, make sure the USB cable and MUT-3 main harness are not damaged.
⚫ Do not perform maintenance work in the engine room during reprogramming.
The cooling fan may operate while reprogramming.
⚫ Turn ignition off for 10 seconds before checking the All DTC after reprogramming and
erase them if any.

REPAIR PROCEDURE (Continued)
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.
1. Open the tailgate and engine hood. Do not close until the program update is completed.
2. Turn the power mode of the power switch on and hold the power switch for 5 seconds or
longer.
3. Turn the power mode of the power switch on and do not turn off until the control program
update is completed.
4. Update the control program with MUT3-SE.

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 ETACS ECU is at the latest level, reprogramming is not necessary.
NOTE: Reprogramming the ETACS ECU with the latest database (e.g., SDBN N240201NR)
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 SEV users go to step 5)
2. Verify the MEDIC 3.5/4 is at version 3.5 and at update 862 or higher.
If your MEDIC 3.5/4 update is at least 862, continue with the Reprogramming Procedure. If
your MEDIC 3.5/4 update is below 862, update your MEDIC as follows.
3. Select the MEDIC 3.5/4 Admin tab and click on “Updates”.

REPROGRAMMING PROCEDURE
! CAUTION
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.
• 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.
SE
• 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.
• For VCI only: Turn the VCI power switch ON. Verify
that the indicator lamp in the upper right corner
Lite
of the screen is green.
! CAUTION
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 battery charger cable onto ground point.
