DTC P1327 ENGINE REPLACEMENT
SUBJECT:
Description: Hyundai is conducting a service campaign 974 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.
Follow the procedure outlined in this bulletin to inspect the vehicle and replace the engine if a DTC
P1327 condition exists. For engine replacement, please ensure to follow standard HMA warranty
policy and use a new engine long block if vehicle is within ("5/60") and a Reman when beyond 5/60
(if available).
