Manufacturer summary

Original wording in English

Some Palisade Hybrid (LX3 HEV) vehicles may illuminate the hybrid system warning light with Diagnostic Trouble Codes (DTC) P0C381C when the vehicle is parked for extended duration. This bulletin provides instructions to update the Hybrid Power Control Unit (HPCU) software to improve the detection logic for DTC P0C381C.

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.
