OBD2 Simulator with two 4x20 LCD Screen display.

This AZ OBD2 simulator is a device that simulates the vehicle OBD2 bus protocol. It has dynamic simulation and real-time LCD display of the main PIDs which is close to the real car environment . It is very convenient and practical for OBD2 car scan developer.

•  Provides real-time display of more than 80 standard parameter IDs

•  Ten Fault codes (DTC) preprogrammed can be set ON/OFF by Edit DTC switch

•  Changing sensor data by build in 8 variable resistors

•  Support Bluetooth ELM adapters

•  Vehicle information such as VIN (Vehicle Identify Number)

•  Vehicle mileage (preprogrammed) 

NOTE: This OBD simulator is independently developed by AZOBD2Scanner for develop and testing AZOBD2Scanner APK for Android.
