PRODUCT IMPROVEMENT CAMPAIGN
NU 2.0L GDI - KNOCK SENSOR DETECTION SYSTEM
(KSDS) ECU LOGIC IMPROVEMENT (PI2106)
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 certain 2017-2018MY Forte (YD/YDm) vehicles equipped with Nu 2.0L GDI engines,
produced from May 19, 2016 through May 7, 2018.
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.

Ensure the KDS GDS is sufficiently charged at 60% or higher prior to reflash.
•
All ECU upgrades must be performed with the ignition set to the ‘ON’ position unless otherwise
stated.
•
Damaged VCI II units should not be used and promptly replaced.
•
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
