Who Is the iCarsoft VOL V4.0 For?
The VOL V4.0 is well suited to Volvo and Saab owners, enthusiasts and independent workshops that need more than basic fault-code reading.
It is a strong choice if you want to diagnose faults across multiple vehicle systems, perform maintenance procedures, run active component tests and access advanced Volvo- and Saab-specific diagnostic functions without moving to a subscription-based workshop platform.
Full-System Volvo & Saab Diagnostics
Unlike a basic OBD2 scanner that mainly communicates with the engine control unit, the iCarsoft VOL V4.0 can access numerous control modules throughout supported Volvo and Saab vehicles.
Depending on the vehicle, diagnostic access can include:
- Engine
- Automatic transmission
- ABS
- Airbag / SRS
- Electronic parking brake
- Steering systems
- Body control modules
- Climate control
- Instrument cluster
- Battery management
- Lighting and comfort systems
- Other manufacturer-specific control modules
Functions include reading and clearing diagnostic trouble codes, viewing live data, system scanning, AutoVIN vehicle identification and access to manufacturer-specific diagnostic information.
Full Bidirectional Control and Active Tests
The VOL V4.0 supports full bidirectional diagnostics, allowing the scanner to send commands directly to supported control modules. This helps test components during troubleshooting instead of relying only on fault codes and live data.
Depending on the vehicle and control module, active tests can include:
- ABS pump activation
- Window regulator tests
- Fuel pump activation
- Wiper and washer motor tests
- EGR valve operation
- Fuel injector tests
- Cooling fan activation
- Transmission solenoid tests
- Door lock and mirror tests
- Other supported actuators
The manufacturer lists more than 15 active-test categories, although exact availability depends on the vehicle and installed control modules.
30 Service and Maintenance Functions
The iCarsoft VOL V4.0 includes 30 service and maintenance functions for supported Volvo and Saab vehicles. These consist of 9 commonly used maintenance functions and 21 higher-level service functions.
Common Service Functions
- Oil / service reset
- Electronic parking brake / brake pad service
- Electronic throttle control
- Steering angle sensor calibration
- DPF regeneration
- Injector coding
- ABS bleeding
- Battery management reset
- TPMS reset
Advanced Diagnostic and Adaptation Functions
Depending on the vehicle, advanced functions can include:
- Gear indicator activation
- Oil pump air purge
- Air/fuel ratio adaptation
- Oil level sensor learning
- Turbo actuator learning
- Fuel pressure valve adaptation
- EGR valve learning
- IMU sensor calibration
- Brake pedal sensor calibration
- Gear position sensor calibration
Exact function availability varies by vehicle model, year and control unit.
VOL V3.0 vs VOL V4.0
The VOL V4.0 is the successor to the VOL V3.0. Both provide advanced Volvo and Saab diagnostics and bidirectional active tests, but the V4.0 introduces major hardware and usability improvements.
| Feature | VOL V3.0 | VOL V4.0 |
|---|---|---|
| Volvo & Saab diagnostics | Yes | Yes |
| Full-system diagnostics | Yes | Yes |
| Bidirectional / Active Tests | Yes | Yes |
| Display | 4-inch | 5-inch touchscreen |
| Operating system | Traditional interface | Android |
| Software updates | USB | Wi-Fi |
| Additional vehicle groups | No | 2 included free |
| CAN-FD | Supported | Supported |
| Lifetime free updates | Yes | Yes |
For users comparing the two versions, the biggest V4.0 improvements are the 5-inch touchscreen, Android platform, Wi-Fi updating and two additional vehicle make groups.
Volvo & Saab Vehicle Coverage
The VOL V4.0 comes pre-installed with dedicated diagnostic software for Volvo and Saab vehicles. The manufacturer states compatibility with supported Volvo and Saab models from approximately 1996 to 2025.
For standard OBD2 connectivity, the manufacturer specifies petrol Volvo and Saab models from approximately 2001 onwards and diesel OBD2 models from approximately 2004 onwards.
Two Additional Vehicle Make Groups Included
In addition to the pre-installed Volvo / Saab software, the VOL V4.0 allows you to download two additional supported vehicle make groups free of charge.
This gives the device three vehicle groups in total without additional diagnostic software subscription fees.
CAN-FD Support
The iCarsoft VOL V4.0 supports the newer CAN-FD communication protocol used by newer vehicle electronics.
It also supports a wide range of traditional automotive communication protocols for older vehicles.
AutoVIN Vehicle Identification
The AutoVIN function can automatically identify supported vehicles through the diagnostic connection, reducing the need to manually enter vehicle information.
If AutoVIN does not identify a particular vehicle, manual vehicle selection can still be used.
Lifetime Free Wi-Fi Updates
Software updates for the VOL V4.0 are included for the lifetime of the device. Updates are downloaded directly through Wi-Fi, with no annual diagnostic software subscription fees.
