This bulletin provides information related to a software update to the Engine Control Unit (ECU) to

The KSDS detects vibrations indicating the onset of excessive connecting rod bearing wear. It is
designed to alert the driver at an early stage of bearing wear before the occurrence of severe
engine damage, including engine failure. If vibrations caused by bearing wear start to occur, the
Malfunction Indicator Lamp (MIL) will blink continuously, and the vehicle will be placed in Limp
Home Mode. This will reduce further damage to the engine and ensure that the vehicle occupants
are not exposed to the risk of a more severe engine failure. At that time, Diagnostic Trouble Code
(“DTC”) P1326, specific to the KSDS, will be recorded in the ECU. The vehicle can continue to be
operated for a limited time in Limp Home Mode, but it will accelerate slowly and have a reduced
maximum speed. Also, engine RPMs will be limited to approximately 1800-2000 RPM.
Please note, since Kia
launched this Product Improve Campaign, Kia has become aware that the
KSDS software version installed on 2014-2015MY Optima vehicles before September 7, 2018 has
an error and requires the installation of a new corrected software. Kia has identified all affected
2014-2015MY Optima vehicles which require the installation of the new corrected software, and
these vehicles are identified under a separate campaign number, PI1802A1, in the WEBDCS.
Kia is requesting the completion of this Product Improvement Campaign on all affected vehicles.
Before conducting the procedure, verify the vehicle is included in the list of affected VINs. Also,
please have your KDS connected to the internet regularly to get the latest software updates
available.

NOTICE
A fully charged battery is necessary before ECU upgrade can take place. It is
recommended that the Midtronics GR8-1299 system be used in ECU mode during
charging. DO NOT connect any other battery charger to the vehicle during ECU upgrade.
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, year.
CAUTION
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
For Optima models included in this TSB:
VINs that start with 5XX are designated Optima (QF/JFa) and produced in the United States.
VINs that start with KNA are designated Optima (TF/JF) are produced in South Korea.
