Manufacturer summary

Original wording in English

Certain Palisade Hybrid (LX3 HEV) vehicles may display a Hybrid system warning light on the instrument cluster with Diagnostic Trouble Code (DTC) P0C381C when the vehicle is parked for long durations. Technical Service Bulletin (TSB) 26-01-079H provides instructions to perform a Hybrid Power Control Unit (HPCU) software update to resolve this condition.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
