*** Retail Vehicles ***
Dealer must perform this Service Campaign whenever an affected vehicle is in the shop for any
maintenance or repair.
When a vehicle arrives at the Service Department, access Hyundai Motor America's "Vehicle
Information Screen (VIS)" via WEBDCS to identify open service campaigns.
Description: Hyundai is conducting a service campaign to enhance the knock sensor logic with the
Cylinder Noise Diagnostic System (CNDS) software update. CNDS is to detect abnormal cylinder
wall scuffing or noise of the engine block before potentially severe engine damage occurs. If
abnormal noise is detected, the Malfunction Indicator Lamp (MIL) will blink continuously. In addition,
DTC P1327 will be recorded in the ECM.
Applicable Vehicles:
 Certain 2019-20MY Elantra (AD*) vehicles with 2.0L Nu engines produced through 7/6/2020
 Certain 2019-21MY Kona (OS) vehicles with 2.0L Nu engines produced through 9/1/2020
 Certain 2019-21MY Veloster (JS) vehicles with 2.0L Nu engines produced through 5/27/2020
NOTE: *Elantra (AD) vehicles have VINs starting with “KMH”.
