4.5 Start Diagnostics

Tap -> "Diagnostic" to enter the vehicle selection page.
2 approaches are provided for you to access the vehicle diagnostic software.
Choose any one of the following ways:
1. VINSCAN enables you to access it more quickly.
In this case, automatic scan (OBD VIN) and manual input (INPUT VIN) are
available.
OBD VIN: In this mode, the diagnostic connector should be plugged into the
vehicle's DLC first, and then a wireless BT communication should be
established between the tablet and the vehicle.
Tap "OBD VIN" to scan the vehicle identification number of the vehicle. Once
scanning is complete and successful, X-431 V+ will enter the diagnostic
software of the vehicle.
Note: Before using this function, the corresponding diagnostic software and Auto
search file need to be downloaded on your tool first while downloading the
diagnostic software.
INPUT VIN: In this mode, you need to input the VIN manually. In general,
vehicle identification numbers are standardized - all contain 17 characters.
VIN characters may be capital letters A through Z and numbers 1 through 0;
however, the letters I, O and Q are never used in order to avoid mistakes of
misreading. No signs or spaces are allowed in the VIN.
The most recognizable location for this number is in the top left corner on the
vehicle's dashboard. Other locations include the driver's door or post, and the
firewall under the hood.
Tap "INPUT VIN" and a screen similar to Fig. 4-25 will appear:
