Ask in plain language and get sourced, cited answers from this vehicle's data — and beyond it.
04Built for the whole team.
Up to 11 users included, each with their own login.
Pricing
$79/month. Everything included.
Or $58/month billed yearly ($699/year — save 26%). Multiple users, premium data for 50 vehicles a month, verified measurements, unlimited AI search and Ask WrenchLane, priority support. Billed from day one.
Start the job
Snap a photo. We'll read the codes.
Already pulled DTCs with your OBD reader? Skip the typing. Take a photo of the reader's screen and WrenchLane reads the codes — add the symptoms by typing or speaking, and the diagnosis starts. Or enter codes manually if you prefer.
The workflow
From fault code to completed repair.
WrenchLane follows the same order your technicians already work in.
01Diagnose.
Enter fault codes and symptoms — typed, spoken or from a photo. WrenchLane returns ranked causes with likelihood and severity.
02Verify.
Check the suspect component with guided measurements, pin values and the wiring diagram for that exact vehicle.
03Repair.
Confirm the cause and follow OEM repair instructions step by step, with a time estimate for every step.
04Build the job.
Add parts, fluids and OEM labour times as you work, then finish the job as a report or invoice.
05Save the vehicle.
Diagnosis, repair and history stay on the car — the next visit starts where the last one ended.
