About 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.
