PRODUCT IMPROVEMENT CAMPAIGN
SUBJECT:

KNOCK SENSOR DETECTION SYSTEM - ECU
LOGIC IMPROVEMENT (PI1803)

 NOTICE
This bulletin has been revised to include additional information. New/revised
sections of this bulletin are indicated by a black bar in the margin area.
This bulletin provides information related to a software update to the Engine Control Unit (ECU) to
install the Knock Sensor Detection System (KSDS) in order to protect the engine from excessive
connecting rod bearing damage. This update is for:
•
•
•
•

All 2011-2013 MY Optima (QF/TF) vehicles equipped with the 2.4L Gasoline Direct Injection (GDI) and
2.0L Turbocharged GDI (T-GDI) engines produced from August 12, 2010 through September 27, 2013;
All 2014 MY Optima (QF) vehicles equipped with the 2.4L Gasoline Direct Injection (GDI) and 2.0L
Turbocharged GDI (T-GDI) engines produced at KMMG from August 28, 2013 through May 15, 2014;
All 2012-2014 MY Sorento vehicles equipped with the 2.4L Gasoline Direct Injection (GDI) engines
produced from April 19, 2011 through February 10, 2014; and
All 2011-2013 MY Sportage vehicles equipped with the 2.0L Turbo Gasoline Direct Injection (T-GDI)
engines produced from December 30, 2010 through August 30, 2013.

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

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.

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) and produced in the United
States. VINs that start with KNA are designated Optima (TF) and produced in South
Korea.
Printed TSB copy is for reference only; information may be updated at any time. Always refer to KGIS for the latest information.
