LOGIC IMPROVEMENT (PI1805)
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 2019MY vehicles listed below:

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.
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
456. UMA THETA 2.4 Knock Sensor Detection System(KSDS) LOGIC IMPROVEMENT (19MY)
458. JF/JFA THETA 2.0/2.4 Knock Sensor Detection System(KSDS) LOGIC IMPROVEMENT (19MY)
459. QL THETA 2.0/2.4 Knock Sensor Detection System(KSDS) LOGIC IMPROVEMENT (19MY)
NOTICE
A fully charged battery is necessary before the ECU upgrade can take place. It is
recommended that the Midtronics GR8-1299 be used in ECU mode during
reflashing or the use of a fully charged jump starter box.
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.
