Campaign 953 Dea2020-03-07. Service bulletin. ENGINE AND ENGINE COOLING; EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; ELECTRICAL SYSTEM:SOFTWARE. Hyundai has developed a new engine monitoring technology called a Knock Sensor Detection System (KSDS). The technology uses software innovations and leverages existing engine sensors to continuously monitor for symptoms that may precede an engine failure. Watch this video to learn more. The KSDS software continuously monitors engine vibrations for unusual patterns that develop as an engine connecting rod bearing wears abnormally that could later cause engine seizure. If vibrations caused by bearing wear start to occur, the malfunction indicator lamp will blink continuously, an audible chime will sound and the vehicle will be placed in a temporary engine protection mode with reduced power and acceleration. At that time, Diagnostic Trouble Code (DTC) P1326 will be recorded in the ECM. In addition, Hyundai will extend the warranty to 10 years and 120,000 miles (up from 100,000 miles) for original and subsequent owners of the covered vehicles for engine repairs needed because of excessive connecting rod bearing damage.

5NP-H9R6R-022019-02-19. Service bulletin. EQUIPMENT. The software update installs a newly developed Knock Sensor Detection System (KSDS) that detects vibrations indicating the onset of excessive connecting rod bearing wear in the engine. The KSDS is designed to alert a vehicle driver at an early stage of bearing wear before the occurrence of engine damage. If vibrations caused by bearing wear start to occur, the Malfunction Indicator Lamp (MIL) will blink continuously, an audible chime will sound, and the vehicle will be placed in Limp Home Mode. At that time, Diagnostic Trouble Code (DTC) P132600, specific to the KSDS, will be recorded in the ECM. 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 with RPMs limited to approximately 1800-2000 RPM. The update will be done free of charge to customers and will only involve the addition of the KSDS software update.
