Save time and money and take the guess-work out of your fault-finding and diagnosis. Allows interrogation of the vehicles ECU to determine the performance of essential emission-based information, to read and clear Diagnostic Trouble Codes (DTCs) and to obtain vital performance data from the vehicles engine and transmission (Petrol 2001 onwards and Diesel 2004 onwards). The size of the code reader belies its power. Unlike many other budget tools, which give only a code, the VS8812 gives a full definition on its colour backlit LCD screen. Also supports the new extended sensor list (SAE J1979 2007) and features freeze-frame, live data and includes I/M Readiness to eliminate drive cycle guesswork, using colour-coded LEDs. These characteristics are usually only found on code readers costing many times more.
