An OBDII/OBD2 scanner is a great addition to any home mechanics toolbelt, allowing you to scan, identify and diagnose potential faults and dashboard warning lights without an expensive trip to the mechanics. The Foxwell ET2707 Diagnostic Scanner is a great example of one of these standalone units, featuring a simple layout and easy to read colour screen for maximum clarity. Capable of producing live and freeze frame data graphing based on a diagnostic check of your engine's systems, this scan tool allows you to read error codes to get an understanding of system status, and remove any redundant or residual codes to help clear pesky warning lights. Suitable for most petrol and diesel vehicles post-2006, this Foxwell engine light checker gives you the advantage of free lifetime updates (direct through supplier website) to ensure that you're always up to date on new codes and information.
