How this glossary was assembled

OEM source

Toyota RM179U1 · 1991 · page 15

The Toyota OEM list (62 terms) is sourced from page 15 of the 1991 MR2 service manual — Toyota's own "Abbreviations Used in This Manual" table.

Community source

MR2OC Common Abbreviations · PeteJ · 2,430 hits

The community list (34 unique terms) is the MR2 Owners Club's own glossary, written by Peter Jones to cover terms the OEM list doesn't — BGB, BEAMS, Mr T, Moonroof, Speed cut, TTE, and the chassis / engine code shorthand the community uses every day.

Cross-validation

3-way diff against community BGB digitisation

The OEM extraction was cross-checked against dobicinaitis/toyota-mr2-repair-manual's independent transcription of the same page. Result: 57 of 62 shared keys agree on both key and meaning, with zero value disagreements. The 5 apparent diffs resolved to 4 markdown-formatting artefacts and 2 typos in the upstream digitisation (BVSC → BVSV; TDDC → TDC) flagged for upstream correction.
