To connect the Autel MS909EV MaxiSYS Ultra EV Diagnostic Tablet to a vehicle for diagnostics, follow these steps:
1. Connect the main cable V2.0 to the Vehicle Data Connector (DB26-Pin) on the VCMI (Vehicle Communication and Measurement Interface) and tighten the thumb screws.
2. Connect the cable's 16-pin adapter to the vehicle's DLC (Data Link Connector), which is generally located under the vehicle dash.
3. Power up the tablet. Ensure the tablet has a charged battery or is connected to the supplied DC power supply.
4. Select one of the three methods - Bluetooth, Wi-Fi, or USB cable V2 - to connect the tablet with the VCMI and establish a communication link. Note that only the USB cable connection should be used when programming.
5. When the VCMI is properly connected to the vehicle and the tablet, the VCMI status button at the bottom bar on the screen will show a green badge, indicating that the system is ready to start vehicle diagnosis.
