Traverse — C1XX (2018–2024)

2018–2019 Confirmed

Premier; required with WBL; the guides print H1Y2, the footnote mark 2 (required when WBL is ordered) attached, and no page prints the bare code (the 2018 guide p.65, the 2019 guide p.92), so the row carries no factory citation

This page aggregates every documented appearance of H1Y in the Chevrolet reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
