Summary
TSB: PRODUCT IMPROVEMENT CAMPAIGN: KNOCK SENSOR DETECTION SYSTEM - ECU LOGIC IMPROVEMENT (PI1802) - 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: * Some 2014MY Optima (TF) vehicles equipped with 2.4L GDI engines, manufactured at KMC from August 29, 2013 through April 25, 2014; * All 2015MY Optima (TF/QF) vehicles equipped with 2.4L GDI and 2.0L Turbocharged GDI (T-GDI) engines; * All 2014-2015MY Sportage (SL) vehicles equipped with 2.4L GDI and 2.0L Turbocharged GDI (T-GDI) engines; * All 2015MY Sorento (XMa) vehicles equipped with 2.4L GDI engines, manufactured from January 3, 2014 through December 11, 2014. 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.

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:
Some 2014MY Optima (TF) vehicles equipped with 2.4L GDI engines, manufactured at
KMC from August 29, 2013 through April 25, 2014;
All 2015MY Optima (TF/QF) vehicles equipped with 2.4L GDI and 2.0L Turbocharged
GDI (T-GDI) engines;
All 2014-2015MY Sportage (SL) vehicles equipped with 2.4L GDI and 2.0L
Turbocharged GDI (T-GDI) engines;
All 2015MY Sorento (XMa) vehicles equipped with 2.4L GDI engines, manufactured
from January 3, 2014 through December 11, 2014.
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.

NOTICE
To assure complete customer satisfaction, always remember to refer to WebDCS
Warranty Coverage (validation) Inquiry Screen (Service → Warranty Coverage →
Warranty Coverage Inquiry) for a list of any additional campaigns that may need to be
performed on the vehicle before returning it to the customer.
ECU Upgrade Procedure:
To correct this condition, the ECU should be reprogrammed using the KDS
download, as described in this bulletin.
Upgrade Event Name
374.XMa Theta 2.4GDI Knock Sensor Detection System (KSDS) ECU Upgrade
375.TF Theta 2.0/2.4GDI Knock Sensor Detection System (KSDS) ECU Upgrade
376.SL Theta 2.0/2.4GDI Knock Sensor Detection System (KSDS) ECU Upgrade
377.QF Theta 2.0/2.4GDI Knock Sensor Detection System (KSDS) ECU Upgrade
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) and produced in the United
States. VINs that start with KNA are designated Optima (TF) are produced in South
