1Feature: The for Godiag GT100+ Ecu Connector is a platform for Obdii protocol communication detection and Ecu maintenance, diagnosis, programming and coding. 2Main Function: Convert the car OBD2 interface into 16 pin for signal detection and electrical level conversion. Can also be connected with any diagnostic tool to tell whether the car communication is good or not. 3Temporary Power Supply: Supply power to the car when you change the battery to avoid the vehicle control module data being lost, automatically locked, when the key remote control fails and the fault light turns on. 4Electronic Current Display: You can intuitively see the current display of the Ecu by connecting the Ecu module with the Banana interface or the DB25 cable, which can make your work much easier. 5Ecu Testing: Intuitively see the current status of the Ecu, then you can check whether the wiring is wrong, if so, there is no need to perform diagnostic communication and can directly repair the Ecu. 6Unique Functions: Convert OBD1 diagnostic interface to the standard OBD2 diagnostic interface. Reset instrument or immobilizer when all keys lost. Adds Canbus Protocol Communication.
