Why Wrenchify works for DIYers
Decode any warning light
P0xxx powertrain, B0xxx body, C0xxx chassis, U0xxx network — get plain-English meaning and next steps.
Scan the VIN with your camera
Point your phone at the door-jamb barcode. Year, make, model, and engine fill in automatically.
Optional Bluetooth OBD scan
Pair a cheap BLE dongle to read and clear live codes on Android, Windows, or Mac with Chrome/Edge.
Real recall + TSB data
Live lookups from NHTSA, not forum guesses. Know if a problem is factory-related before you buy parts.
Know how long a job takes
Flat-rate labor hours help you decide whether to tackle it Saturday morning or call a shop.
