UPDATE PLANReady for the newest Volvo & Saab communication standard.
CAN-FD (Controller Area Network – Flexible Data-rate) is a next-generation automotive communication protocol adopted by Volvo/Saab.
What is CAN-FD?
CAN-FD (Controller Area Network – Flexible Data-rate) is the next-generation evolution of the classic CAN bus, now adopted across the newest Volvo/Saab platforms.
- Flexible Data-Rate: Transfers larger data frames at faster speeds than classic CAN, keeping up with modern vehicle electronics.
- The New Factory Standard: Adopted by Volvo/Saab on the latest platforms.
CAN-FD Ready, Out of the Box
- Native CAN-FD Support: Talks the CAN-FD protocol directly from the standard OBD2 port.
- Newest Models Covered: Keeps the VOL V4.0 connected to the latest Volvo/Saab chassis in its coverage range.
One Tool, Every Protocol
CAN-FD is only the newest layer — the VOL V4.0 speaks the full range of protocols used across decades of Volvo/Saab models.
- Beyond CAN-FD: Also supports classic CAN, K/L-Line and the other factory protocols listed in the full specifications below.
- Old or New, One Tool: From early CAN models to today's CAN-FD platforms, the VOL V4.0 selects the right protocol for the car.
Stop guessing. Command the part and watch it respond.
The iCarsoft VOL V4.0 bidirectional scan tool supports active component testing and full bidirectional control for most vehicle modules. It sends custom commands and retrieves real-time data to execute targeted functions, including window, mirror, and door lock testing, as well as throttle adjustment — allowing you to pinpoint faults quickly.
Body & Comfort Active Tests
You can directly command individual components and watch them respond in real time — identify the faulty part in minutes, without relying on trial-and-error.
- Command Window Regulators: Drive windows up and down straight from the scanner to isolate bad switch clusters in seconds.
- Trigger Door Locks & Side Mirrors: Actuate locks and mirrors on demand to pinpoint body control module glitches.
Powertrain & Fuel Active Tests
Send commands straight to the engine-side modules and watch each component respond in real time — no cabin switches, no waiting for the fault to reappear.
- Kick On the Fuel Pump: Activate the fuel pump instantly to verify fuel pressure dropping issues.
- Modulate Throttle Opening: Sweep the throttle to check for sticking carbon deposits.
Chassis & Brake Active Tests
Take direct control of the hydraulic hardware that normally only responds while driving — essential for a proper brake service.
- Cycle the ABS Pump Motor: Run the pump on command to purge trapped air during brake bleeding.
Dynamic Output Tests
Beyond the headline tests, the VOL V4.0 can exercise nearly every electrically driven component on the car.
- Any Actuator or Solenoid: Run dynamic output tests on virtually any onboard actuator or solenoid in minutes.
- Confirm Before You Buy: Watch the module respond live and confirm the failed part before ordering a replacement.
Plug in. Your Volvo or Saab names itself in seconds.
Skip the manual VIN typing — simply plug in, and the tool identifies your vehicle in seconds. No typos, no extra lookup time. This boosts accuracy, eliminates input errors, and delivers a smoother, more reliable diagnostic experience.
One-Plug Identification
- Automatic VIN Read: Simply plug into the OBD2 port and the VOL V4.0 identifies your vehicle in seconds.
- No Extra Lookup Time: Skip manual VIN typing and model-menu digging entirely — go straight to diagnostics.
Accuracy Built In
- Eliminates Input Errors: No typos means the scanner always loads the exact software profile for your vehicle.
- Smoother, More Reliable Sessions: Correct identification from the first second delivers a more reliable diagnostic experience.
Manual Selection Backup
AutoVIN depends on individual vehicle ECU protocols. If AutoVIN skips your car, it doesn't mean the device is faulty — you always have a second way in.
- Manual Selection Mode: Pick your model from the menu and every diagnostic and service function works exactly the same.
- Growing VIN Database: Send your VIN to the support team and it will be verified and added in the next software update.
Diagnose in your language, wherever you wrench.
Volvo/Saab scanner VOL V4.0 supports English, German, French, Dutch, Spanish, Czech, Swedish, Russian, Hungarian, Norwegian, Portuguese, Italian, Polish, Danish, and Finnish.
