## What is WrenchLane?

WrenchLane helps professional auto repair workshops diagnose vehicle problems faster and repair them more accurately. Powered by AI, it combines fault codes, symptoms, real repair data, and OEM repair instructions into a guided workflow that cuts diagnostic time and reduces comebacks.

HOW IT WORKS

Enter your vehicle using a license plate or manual selection. Add fault codes by typing them or by photographing your OBD reader display, and describe symptoms via voice or text. WrenchLane analyzes everything together, not in isolation, and delivers ranked possible causes based on real repair patterns specific to that vehicle and fault combination.

KEY FEATURES

Fault Code Intelligence: Instant context on diagnostic trouble codes and their implications for each specific vehicle.

Most Likely Cause Analysis: Ranked diagnostic starting points drawn from real repair patterns, so you know where to look first.

Motor Premium Content (US, Canada, Mexico): Wiring diagrams and component locations integrated alongside the diagnostic workflow.

InfoPro Premium Content (EU): Wiring diagrams, repair manuals, timing belt and chain manuals, technical drawings, component locations, adjustments (torques, clearances, capacities), OEM repair times, dashboard warning-light meanings, technical service bulletins, wear parts intervals, fluids & lubricants, and service & maintenance schedules — integrated alongside the diagnostic workflow.

Verification-First Approach: Minimum checks needed to confirm a hypothesis before replacing parts. Reduces unnecessary part swaps and comebacks.

TSB Matching: Automatically surfaces relevant Technical Service Bulletins for the vehicle and fault combination.

Multiple Input Methods: License plate lookup or manual vehicle selection; fault codes via typing or OBD reader photo capture; voice input for symptoms.

Diagnostic History: Full records of past cases for reference and continuity.

Invoice Generation: Generate professional invoice drafts directly from completed diagnostics. Select confirmed causes, describe additional work, list parts replaced, and get a ready-to-use invoice.

Smarter Recommendations: Considers time, cost, and complexity when suggesting next steps.

WHO IT'S FOR

Built for independent mechanics, workshop teams, and multi-location operations. Developed iteratively with feedback from hundreds of independent workshops.

## Version history (last 5 releases)

### 3.6 — 2026-07-22

Our biggest release yet: one search bar that answers anything about the vehicle, sourced answers with citations, and a diagnosis wired straight into the technical data.

SEARCH AND ANSWERS
- One search bar for the whole vehicle: parts and components, repair manuals, wiring diagrams, fuse and relay locations, fault codes, adjustments and torque specs, lubricants, repair times and OEM bulletins. Ask in plain language, in any of 26 languages, and jump straight to the exact spec, manual or diagram.
- Ask WrenchLane: when the answer is not in the vehicle data (part numbers, suppliers, prices, fitment, procedures), WrenchLane brings it in from outside sources, scoped to your exact vehicle and backed by citations you can open and verify. Now with matched manual diagrams, images and repair videos. Every question you ask is saved, reopen any of them with one tap.

DIAGNOSTICS
- Verification steps on every cause: each possible cause lists the exact components to check, in order. Locate the part, then run the guided wiring-diagram test with step-by-step measurements, without leaving the diagnostic page.
- Error code diagnosis and bulletins: guided component tests for your error codes, plus manufacturer bulletins and recalls matched to your codes and symptoms.
- Technical-data links in the diagnosis: tap a highlighted part name to open the component's diagnosis, location or drawings.

TECHNICAL DATA (available in European countries)
- Electronics: every electronic system with its wiring diagrams, components, fuses and physical locations, matched to your vehicle's model year, body style and steering side. Read pin tables and trace CAN-Bus signals.
- OEM info: the manufacturer's own SmartCASE cases, recall data and technical service bulletins, filterable by vehicle area, fault code, defect or date.
- Wiring diagram legend: every diagram lists the components drawn in it. Tap a component to zoom straight to it, or tap a part on the diagram to find it in the legend.

SERVICE
- Service reports: finish a service and save it as a report, then reopen or edit it anytime from the vehicle page or the garage history.
- Print and PDF export across the app: reference manuals and OEM data, the diagnostic report, and the service and maintenance sheet.
