Frequently Asked Questions

Q: What's the difference between CS520 and CS606?
A: The CS520 is more compact with 10 reset functions and a 3.5" screen, while the CS606 has 21 reset functions, a 5" touchscreen, and broader vehicle coverage. CS520 is ideal for mobile mechanics; CS606 is better for full-service workshops.

Q: Can this scanner work on 24V trucks and buses?
A: Yes! The CS520 supports both 12V and 24V vehicle systems, making it versatile for workshops servicing both passenger vehicles and commercial fleets.

Q: How do I update the software?
A: Connect the CS520 to your computer via USB, download the latest software from Autool's website, and follow the update wizard. Updates are free for life.

Q: Does it have bi-directional control?
A: The CS520 has limited bi-directional functions for specific reset procedures (EPB, throttle adaptation). For full active testing, consider the CS606.

Q: Is it suitable for diesel vehicles with DPF?
A: Yes. The CS520 supports DPF regeneration on most diesel vehicles, a critical function for modern diesel maintenance.

Why Autool CS520 is Perfect for Mobile Mechanics

The CS520 hits the sweet spot between capability and portability. At just 500g, it slips into a pocket or tool bag, yet delivers multi-system diagnostics and reset functions that rival scanners twice its size and price.

The rechargeable battery is a game-changer for mobile mechanics. Unlike vehicle-powered scanners that require the ignition on, the CS520 can diagnose with the vehicle off, saving battery power and allowing diagnostics in any location. The 3-5 hour battery life handles a full day of service calls.

The 12V/24V support makes it invaluable for workshops serving mixed fleets—diagnose a Maruti hatchback in the morning, a Tata truck in the afternoon, all with one tool. The 10 reset functions cover the most common service procedures: oil resets, EPB service, steering angle calibration, battery registration, and DPF regeneration.

For independent workshops and mobile mechanics who need professional capabilities without the bulk and cost of high-end scanners, the CS520 delivers exceptional value. It's the tool you'll reach for first, every time.
