NOTE
After the VCI device is successfully connected to the vehicle, the Power LED on the
device illuminates, and a brief beep sound will be heard.
VCI Connection
After the VCI device is properly connected to the vehicle, the Power LED on the VCI
device illuminates solid green light, and is ready to establish communication with the
tablet.
The J2534 ECU Programming Device, which comes with the MaxiSys MS908S Pro tool
kit, supports 2 communication methods with the tablet: BT, and USB.
Pairing Up via BT
Among all methods, BT pairing is recommended as the first choice for the
communication between the tablet and the VCI device. The working range for BT
communication is about 210 feet (70 m); this means you can perform vehicle diagnosis
freely around the workshop with greater convenience.
If you use more than one VCI device to connect to the test vehicles when customers
are many, you can perform vehicle diagnosis on various vehicles conveniently, by
pairing the tablet separately to each of the VCI devices connected to the different test
vehicles, via BT, without the need to repeat the plugging and unplugging procedure,
which is unavoidable through traditional wired connection, thus saves you more time
and provides more efficiency.
➢ To pair up the tablet with the VCI device via BT
1. If not already done, power up the tablet.
2. Select the VCI Manager application from the MaxiSys Job Menu.
3. When the VCI Manager application is opened, the device automatically starts
scanning for available VCI devices around for BT pairing. The found devices
