Icarsoft OBD II VOL V4.0 Compatible with: Saab, Volvo

The Icarsoft VOL V4.0 is a professional vehicle diagnostic device for Volvo and Saab vehicles. It was developed for ambitious private users, car enthusiasts, independent specialized companies and professional workshops.
The device provides manufacturer-level diagnostic capabilities and covers almost all supported control units and vehicle systems, from engine, transmission, ABS and SRS airbag to comfort, safety and body systems. In addition, active tests, adjustments, calibrations and a total of 30 service functions are available.
The VOL V4.0 comes with pre-installed diagnostics software for Volvo and Saab and is ready for immediate use. In addition, two further groups of vehicle brands can be selected free of charge and downloaded via WLAN.
According to the manufacturer, the device is compatible with Volvo and Saab models from the years 1996 to 2025. Thanks to powerful hardware, 5-inch touch screen and lifetime free online updates, the device is suitable for diagnosis, maintenance and repair of supported vehicles.

Powerful hardware
The VOL V4.0 is equipped with a 12.70 cm/5-inch touch screen, Android operating system, quad-core processor with 1.3 GHz, 64 GB memory and a 5,000 mAh rechargeable battery. According to the manufacturer, the battery life is approx. six hours in continuous operation. The clear user interface enables a fluid and comfortable use.

Lifetime free online updates
Unlike many other diagnostic tools, the VOL V4.0 does not incur annual subscription fees. Software updates are provided free of charge over WLAN for life. Diagnostic logs, functions and vehicle coverage are continuously expanded and improved.

Support for the current CAN FD protocol
CAN-FD (Controller Area Network - Flexible Data Rate) is a modern vehicle communication protocol that can be used in newer Volvo and Saab vehicles or their supported controllers. The VOL V4.0 supports CAN-FD in addition to the usual older diagnostic protocols.

Advanced bi-directional control
The VOL V4.0 supports active tests and the bi-directional control of many available control devices. The diagnostic tool sends specific commands to individual vehicle components and evaluates their response in real time. This makes it easier to narrow down errors without replacing components on suspicion.
Examples of supported active tests on compatible vehicles:
Drive the ABS pump motor and support the brake system bleeding
Raise and lower the power window to test switches, wiring and actuators
Activate the fuel pump and check the function or pressure build-up
Operate the throttle valve opening and check for stiffness or debris
Operate door locks and exterior mirrors to limit faults in the body control system
Perform output and actuator tests on numerous other actuators, solenoid valves and vehicle modules

Automatic vehicle identification using AutoVIN technology
After connection, the VOL V4.0 can automatically detect supported vehicles using the vehicle identification number. Manual input of the VIN/VIN is not required for compatible vehicles, which prevents input errors and accelerates diagnostics.

Multi-language user interface
Supported languages: German, English, French, Dutch, Spanish, Czech, Swedish, Russian, Hungarian, Norwegian, Portuguese, Italian, Polish, Danish and Finnish.

Full OBD2 test modes
The device supports all 10 OBD2 test modes for vehicles with OBDII/EOBD-/OBD-/OBD-/KOBD-/CAN-/CAN-FD standards starting from the year of manufacture 1996, including read and delete error codes, I/M readiness, live data, freeze frame data, vehicle information, O2 sensor test, on-board monitoring, EVAP system test as well as reading out pending error codes.

Save and print diagnostic reports
Already tested vehicle systems can be quickly accessed and diagnostic reports can be saved, shared and printed. The feedback function can be used to provide diagnostic information to technical support if required. You can print saved diagnostic reports using a Windows PC and a USB connection.

Supported vehicle protocols
ISO 9141-2, ISO 14230-2, ISO 15765, K/L-Line, flashing code, SAE J1850 VPW, SAE J1850 PWM, ISO 11898 (High Speed, MiddleSpeed, Low Speed and Singlewire CAN), CAN-FD, SAE J2610, GM UART, UART Echo Byte Protocol, Honda Diag-H Protocol, TP2.0 and TP1.6.
