Best obd2 readers and scanners
The computerised OBD2 reader systems started operating as early as the year 1969 on Volkswagen’s fuel-injected models. These very basic versions would illuminate a few malfunctions by indicating wherever there was any problem, however, they did not give any useful and comprehensive diagnostic information or the exact nature of the identified problem.
Later on, new OBD2 readers and scanners, using a digital communication-port that relied upon series diagnostic trouble-codes, were established by the introduction of an internet-enabled assembly line diagnostic-link (ALDL), which could identify a problem and fix it very quickly. Since then many OBD2 scanners have been manufactured including Nitro OBD2.
