OEM manuals

Code: RM179U1
Covers: SW20 Rev 1/2 — engine, suspension, axle, brakes, steering
Format: Scanned PDF, 467 MB
Tier: OEM MANUAL
Status: Awaiting OCR. Pure scanned images; needs vision-OCR pass before structured extraction.

Code: RM285U
Covers: SW20 Rev 3 — engine mechanical, body, brake, charging, clutch, ignition, srs/airbag, starting, steering, suspension, transaxle, A/C, maintenance
Format: 416 text-extractable PDFs across 16 sections, 2,067 pages, 1,483 kB of recoverable text
Tier: OEM MANUAL
Extracted so far: 214 SST tool numbers, 69 spec records (capacity / pressure). Torque tables, vehicle part numbers and component lists live in image regions and are pending the next extraction pass.

Covers: All electrical systems: ABS, charging, cruise control, ECT, EHPS, 3SGTE engine, 5SFE engine, fog/headlamps, ignition, power source, power windows, radio, RCM, relay locations, SRS, start, taillights, theft det, troubleshooting, wiper
Format: ~50 component PDFs + one consolidated PDF + one hi-res consolidated PDF
Tier: OEM MANUAL
Status: In hand. Component-level extraction is its own pass.

OCR the 1991 RM179U1. Pure scan; macOS Vision or Claude vision pass to recover its body content into searchable text. Then structured extraction can run.
Comprehensive text extraction from the 1993 RM285U. Beyond capacity / pressure: procedures, service intervals, diagnostic ladders, warnings, component descriptions. Multiple record types into the database.
Image-region extraction for the 1993 spec tables. Torque values, vehicle part numbers, component lists live in image-based tables (no ruled borders, so plain text extraction strips the column structure). Either OCR each spec page directly or use vision-LLM extraction.
Wiring-diagram extraction. 50+ system-level diagrams. Image-only; structured extraction means OCR + spatial parsing.
Cross-validation against third-party sources. Once OEM part numbers are in the database, validate against twosrus.com, MR2 Heaven, MR2-Ben, Amayama / EPC for current availability and supersession status.
