 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 2019MY vehicles listed below:
Year

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.
KiaeBay logo 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.

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.

 NOTICE
It is recommended to ALWAYS check the Electronic Parts Catalog (EPC) to locate
the ECU Part Number respective to Auto/Manual Mode ROM IDs. DO NOT reference
the parts label affixed to the ECU.
