ENGINE MONITORING LOGIC (SERVICE CAMPAIGN 982)

 IMPORTANT

*** Retail Vehicles ***
Dealers 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 the “Vehicle Information” screen via
WEBDCS to identify open campaigns.
Description:
Hyundai is conducting a campaign to enhance the knock sensor software to detect abnormal engine
bearing noise before potentially severe engine damage occurs. If abnormal engine bearing noise is
detected, the Malfunction Indicator Lamp (MIL) will blink continuously, and the vehicle will be placed
in Engine Protection Mode allowing the customer to drive to the nearest Hyundai dealer for diagnosis
and repair. In addition, DTC P132600 will be recorded in the ECM. The vehicle can continue to be
operated for a limited time in Engine Protection Mode, but it will accelerate slower and have a
reduced maximum speed. Engine RPMs will be limited to approximately 1800-2000 RPM.

NOTICE
Applicable vehicles with previous ECU Update under Campaign 966 will need new ECU Update to
revise the engine monitoring logic to meet Campaign 982 requirements.

Applicable Vehicles:
• Certain 2017-2018 MY Sonata Hybrid/Plug-In (LF HEV/PHEV) vehicles with Nu 2.0L GDI engines

powertrain communication and to prevent system errors.
