Phingoc in trouble:

The laptop is a Dell D630 with a china SDconnect C4.

Xentry 03/2012

DAS 03/2012

It was all working fine last i used the machine.

So.. I connect the MUX to the car (smart 451), and then the lanwire to the mux and computer. Then i turn on the ignition.

In xentry i choose Smart -> 451 -> Diagnostic -> Das opens

in das: Identify car by control unit. After a few seconds some update thing appears and disappears followed by an error.(see att.) Fault (1.2)-2.503.9901. Cannot connect to car.




Doesnt work with wire or wireless.

Please help me.

Delete the 3 “update” folders in C:\program files\SDconnect toolkit (or rename them).. then perform a repair of your SDNetControl by pressing Start\Programs\Service\Setup SDNetControl .. it will start up and ask what you want to do, select repair.. let it do its thing and then go back and delete/rename the update folders in C:\program files\SDconnect toolkit then REBOOT when its done… that should get you up and running.. it is VERY important to REBOOT after deleting the update folders!!!
