Lumina — second generation (1995–2001)

1998–2001 Factory-verified

The 2000 and 2001 lists print "Cluster INST, Oil, Cool Temp, Volts, Trip Odom, Tach" for UH6, which is UB3's wording and UB3 is printed in the same lists, so it is read as a copy misprint (4 list entries read Indicators); 2000-2001 added from those lists.

2024 Single-source

This page aggregates every documented appearance of UH6 in the Chevrolet reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
