CHECK ENGINE LIGHT ON? START HERE. Connect your compatible OBD2 scanner, tap Scan, and see the code, what it may mean, and the cheapest useful test to run next. ONE SCAN SHOWS YOU β’ The code your car returned β’ How urgent the returned code may be β’ The cheapest useful test to run next β’ Which electronic systems were checked β’ Which systems were not checked NO GUESSWORK A trouble code is a clue, not proof that a part is bad. ScanWrench keeps the code, freeze frame, readiness, and supporting readings together so you can test before buying parts. HONEST COVERAGE Standard engine codes and manufacturer-specific systems are not the same thing. ABS, airbag, stability-control, and other enhanced reads appear only when the exact car, scanner, and read are supported. An unchecked system is never shown as clear. SAVE AND SHARE Keep scan results on your device and create a readable PDF when you need to show a mechanic, seller, or buyer what the car returned. YOUR DATA, YOUR CHOICE Use optional account features, keep scans only on this device, or choose Save Nothing. ScanWrench explains what will be sent before anything leaves your phone. FREE INCLUDES Get 3 complete scans each month, scanner checks, code reading, carefully gated code clearing, live-data preview, and offline receipt verification. Bring your own compatible Bluetooth Low Energy or Wi-Fi OBD scanner. ScanWrench does not sell hardware. Manufacturer-specific data is available only for exact supported configurations. Use ScanWrench while safely parked. It is an informational diagnostic tool, not a physical inspection, guaranteed repair, or substitute for a qualified professional.
