Manufacturer summary

Original wording in English

Certain Palisade Hybrid (LX3 HEV) vehicles equipped with the 2.5T-GDI HEV engine may set DTC P050500/P050600. This bulletin provides instructions to perform a software update on the Engine Control Module (ECM) 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.
