Want a foolproof way to fight back against dishonest mechanics who want to rip you off? Read on... When your vehicle's check engine light goes on, it could mean anything from a loose gas cap to a faulty part costing hundreds.

The problem is, only repair shops can access the OBD codes that indicate what's wrong. And that makes you vulnerable to fraud. But no more! Simply plug this Tornado Tools unit into your vehicle's on-board diagnostics (OBD) port and it relays vital information codes to tell you exactly what's wrong. No unnecessary trips to the repair shop. It even resets the light. Every driver should own one! Virtually all cars 1996 and newer have an OBD port.
