About EV Manual

EV Manual (ev-manual.com) is a global vehicle repair technical data center that covers both new-energy and conventional vehicles with repair manuals, wiring diagrams, DTC fault-code lookup, VIN decoding and full factory parameter sheets. In one sentence: it is the workshop-grade data library that lets a technician identify any vehicle from its 17-digit VIN and open the exact factory document for that model version.

What we provide

EV Manual provides five core data services: model-specific repair manuals and wiring diagrams, a DTC fault-code lookup with repair suggestions, 17-digit VIN decoding with three confidence levels, a full factory parameter sheet for every model version, and an EPC parts catalog that is being expanded continuously. As a result, a technician can move from vehicle identification to the relevant circuit diagram without leaving the platform.

• Repair manuals & wiring diagrams — model-specific workshop documentation, browsable online, downloadable as PDF with token credits, printable with watermark. For example, a 2019 Toyota Camry wiring diagram opens in seconds once the VIN prefix is matched.
• DTC fault-code lookup — definition, common causes and repair suggestions with related wiring diagrams linked directly from the code page.
• VIN decoding & parameter sheets — decode any 17-digit VIN to its exact model version and open the full factory parameter sheet (dimensions, engine / motor, battery, transmission, chassis and more). The decoder follows the ISO 3779 VIN standard.
• EPC parts data — parts-catalog coverage is being expanded continuously, brand by brand.

Who uses EV Manual

Three groups use EV Manual daily: independent repair shops that need factory data without a dealer subscription, parts sellers who must confirm the exact model version before listing a component, and diagnostic-tool makers who embed our data through the API. In addition, dealer groups run the platform under their own domain as a white-label service, so their customers never leave the dealer website.

• Repair shops — a 24-hour free trial and per-brand subscriptions keep the cost aligned with real usage.
• Parts sellers — the VIN-anchored hierarchy (Brand → Series → Year → Model → Fuel) eliminates wrong-part orders caused by similar model names.
• Developers & platforms — JS widget, REST API and white-label CNAME cover every integration depth. See API and Partnership.

Platform architecture

The public site is fully static while all account, order and data-library functions sit behind a private API, so the pages a visitor loads are fast, cacheable and hard to attack. However, this separation also means the raw data files are never directly exposed on the public web server — a deliberate design choice that keeps the dataset safe even if the frontend is compromised.

• Static frontend + API backend separation — the public site is fully static (fast, cacheable, hard to attack), while accounts, orders, tokens and the data library sit behind a private API. Data files are never directly exposed.
• Multi-language — the interface is available in 14 languages and the technical content is being translated continuously.
• API access — repair shops, dealers and partner platforms can integrate via JS embed, REST API or white-label CNAME.

Data sources & editorial process

Technical content is compiled from brand official technical publications, then reviewed and released by the EV Manual technical content team, and the current dataset was updated on 2026-10-15. Because vehicle data changes with every model year, the team refreshes the dataset on a rolling basis rather than in rare big releases; as a result, a 2026 model version typically appears within weeks of its official publication.

Every VIN decode carries an explicit match level — exact 8-character prefix, WMI fallback, or brand-level candidates — so users always know how confident the result is. This transparency is a core editorial principle: no silent guesses.

Why technicians choose EV Manual

Technicians choose EV Manual because it replaces multiple brand-by-brand dealer subscriptions with one search box: instead of keeping a separate portal login for every marque they service, they paste a VIN or pick Brand → Series → Year → Model → Fuel and open the exact factory document. In practice this cuts vehicle identification from several minutes of cross-checking to a few seconds, and the same search reaches manuals, diagrams, DTC data and parameter sheets at once.

• One search, five data types — repair manual, wiring diagram, DTC definition, parameter sheet and EPC data all resolve from the same VIN query.
• Confidence shown, not hidden — every VIN decode states its match level, so a wrong identification is caught before a wrong part is ordered.
• Predictable cost — a 24-hour free trial, per-brand subscriptions and non-expiring tokens mean a workshop pays only for what it actually exports.
