IMPROVEMENT WHILE BATTERY CHARGING (SA427)

This bulletin provides the procedure to upgrade the Battery Management System (BMS) and
Full Auto Temperature Control (FATC) software on some 2016-2017MY Soul (PS EV) vehicles,
produced from May 21, 2015 through August 29, 2017, in order to improve air conditioning
operation while the battery is charging. To correct this concern, apply the improved logic to the
following two (2) systems: BMS and FATC using the KDS ECU Upgrade function as described
in this bulletin. For confirmation that the latest reflash has been applied to a vehicle you are
working on, verify the ROM ID using the table on page 3 of this bulletin. Before conducting the
procedure, verify the vehicle is included in the list of affected VINs.

A fully charged battery is necessary before ECU upgrade can take place. It is
recommended that a battery charger is used in ECU mode during reflashing or
the use of a fully charged jump starter box connected to the battery.
DO NOT connect any other battery charger to the vehicle during ECU upgrade.
Ensure the KDS or GDS is sufficiently charged prior to reflash.
All ECU upgrades must be done with the ignition key in the ‘ON’ position.
Be careful not to disconnect the VCI-II connected to the vehicle during the ECU
upgrade procedure.
DO NOT start the engine during ECU upgrade.
Do NOT turn the ignition key ‘OFF’ or interrupt the power supply during ECU
upgrade.
When the ECU upgrade is completed, turn the ignition ‘OFF’ and wait 10 seconds
before starting the engine.
ONLY use approved ECU upgrade software designated for the correct model and
model year.

 NOTICE
Before attempting an ECU upgrade on any Kia model, make sure to first determine
whether the particular model is equipped with an immobilizer security system.
Failure to follow proper procedures may cause the PCM to become inoperative after
the upgrade and any claims associated with this repair may be subject to
chargeback.

 NOTICE
It is recommended to ALWAYS check the Electronic Parts Catalog (EPC) to locate
the ECU Part Number respective to Auto/Manual Mode ROM IDs. DO NOT reference
the parts label affixed to the ECU.

Printed TSB copy is for reference only; information may be updated at any time. Always refer to KGIS for the latest information.
