1. GENERAL INTRODUCTION
The XTOOL XT90 smart diagnostic system (referred to as the “Scan Tool”) is an advanced scanning tool based on the
Android operating system. It supports multiple languages and is suitable for different countries and regions. The advantage
of this OBD-II (On-Board Diagnostics version 2) scanner is its comprehensive functions and its ability to quickly provide the
user with more accurate diagnostic information.

VEHICLE CONNECTION
WIFI CONNECTION
The WIFI connection method is shown in the figure below:
The scan tool must be connected to the vehicle’s OBD-II port so that the tablet can establish correct vehicle communication.
Please perform the following steps:
1 Turn on the tablet
2 Connect VCI with Vehicle via main test cable and OBD adapter, make sure WIFI connection works fine
3 Switch on the ignition and tap on the Diagnostic application to start your diagnosis.
WIRED CONNECTION
When using functions such as ECU programming & coding, please use the USB 3.0 to TYPE-B main cable to connect the
tablet to the VCI box to prevent the failure of function execution due to unstable data transmission and thus any other
damage.
 Note: The vehicle’s DLC is not always located under the dash; for the location of the DLC, please refer to
the vehicle owner’s manual. Some older vehicles are not compatible with the OBD Ⅱ -16 adapter, please make
sure you’re using the correct adapter.

1. Type-C to Type-B cable
2. DB15 Main Test cable
3. OBDII-16 Adapter
 For models with DoIP protocol communication, please be sure the device is connected to vehicle by wire.
SELF-TEST
The self-test is mainly used to detect whether there is a fault in the internal hardware of the device. When performing the
self-test function, please do not connect the VCI box or tablet directly to the vehicle’s OBD port, otherwise irreversible
damage may be caused to your vehicle!
•Plug the power cord into the 12V DC port of the VCI box
•Enter the following path: Main Menu>>Setting>>Self-test, make sure the device is not connected to any vehicle, click
OK to perform self-test function

⚫Precautions for Diagnosis
1. The voltage range on the car: +9~+36V DC;
2. When testing some special functions, the operator must operate according to the prompts and meet the test conditions.
For some models [special functions], the conditions that need to be met are: engine water temperature 80 ℃~105 ℃, turn
off headlights and air conditioners, keep the accelerator pedal in the released position, etc.;
3. The electronic control systems of different models are very complicated. If you encounter situations where it is impossible
to test or a large amount of test data is abnormal, you can search for the ECU of the vehicle and select the menu for the
model on the ECU nameplate;
4. If the vehicle type or electronic control system to be tested is not found in the diagnostic function, please upgrade the
vehicle diagnostic software to the latestversion using the Updates menu or consult the XTOOL technical service department;
5. Only wiring harnesses provided by XTOOL and designed for the scan tool are permitted to be used with this scan tool to
avoid damage to the vehicle or the scan tool;
6. When running a Diagnostics function, it is forbidden to shut down the scan tool directly. You should cancel the task before
returning to the main interface and then shutting down the scan tool.
2. DIAGNOSTIC
The N9EV supports two diagnostic modes, EV mode and normal diagnostic mode, both of which support diagnostics, but
there is a difference in the models covered by their diagnostic functions. EV mode supports diagnostics for pure electric
vehicles and hybrid models only. General diagnostic mode supports gasoline, diesel, hybrid and pure electric models. It
should be noted that some pure electric vehicles can only be used in EV mode, such as Tesla. In addition to diagnostic
functions, EV mode also features battery pack dynamic inspection and component testing.

8
The diagnostic application can read ECU information, read and clear DTC (Diagnostic Trouble Codes) and check live data
and freeze frame data. The Diagnostic application can access the ECU of various vehicle control systems, including the
Engine, Transmission, Anti-lock Braking System (ABS), Airbag Safety Restraing System (SRS), Electronic Parking Brake
system (EPB) and perform many types of actuation tests.
BEGINNING DIAGNOSTIC TESTING
After the tablet device is properly connected to the vehicle, you could start the vehicle diagnosis.
VEHICLE SELECTION
Click the “Diagnostic” icon on the main screen and get into the diagnostic menu. Like the immobilizer menu, the brands will
be shown on the screen. Select the region of your vehicle, click the correct brand, and start the diagnostic process.
For some of the vehicle brands (like Volkswagen), when you click on the software, there are several ways to select the
model or system you want to run a diagnostic, including Automatic Detection, Manual Selection, and System Selection.
