This units can be used in any vehicle manufactured since 1996. Parents of young drivers, auto rental companies, and driver education schools can use this unit to identify unsafe driving habits, such as rapid acceleration, hard braking, or speeding. Drivers receive constructive feedback on their “behind the wheel” habits, which encourages them to improve their driving and help reduce vehicle maintenance costs, fuel costs, and pollution. Using the OBD II system can identify potential risks before they become expensive problems

Vehicle Tracking System with OBD Function:
 ° Diagnostic trouble codes monitoring and car running condition parameters reading including RPM, speed, ECT, MAF, TP etc 
 °  Driver behaviour monitoring, remote report the hard acceleration, hard deceleration, hard braking, idle engine, speeding,, fatigue driving alarm to monitor centre. 
 °  Low voltage monitor 
 °  Real time location tracking and history trace replay
°  U Blox GPS module and Telit GSM module
