I would like to know about funtion of Universal Connector that is provided with X431 Master, can anyone help help me?
The main cable and Smart 16-E connector integrate the functions of all OBDII connectors, including CAN connectors. You may need to purchase a Chrysler-16 connector for some models of vehicles depending on the system you are trying to communicate with.

I have x431 master and when I am try to scan Vehicle with it, at the final stage it give the error, Please guide me?
Here some issues based in our experiences.
1.- Check for cigarret lighter to have power, if not check and replace fuse.... we have found that some Honda vehicle can not be scanned when this fuse is blowed.
2.- Check for proper and solid 12.5 volts or more continuos current, for some reazon having just few volts below it will cause the tool for not reading the ECU.....
