What Is the Vdiagtool Vd70s Scan Tool?

If you’ve ever been frustrated by a check engine light or a mysterious car noise, you’re not alone. Modern vehicles are packed with sensors and computers that monitor everything from engine performance to brake function. When something goes wrong, these systems generate trouble codes—but without the right tool, you’re left guessing. That’s where the Vdiagtool Vd70s scan tool comes in.

This handheld diagnostic device is designed to read, interpret, and clear diagnostic trouble codes (DTCs) from your vehicle’s onboard computer. But it does much more than just show you a code. The Vd70s gives you access to real-time data, system status reports, and detailed explanations of what each code means. Whether you’re a weekend mechanic, a car enthusiast, or a professional technician, this tool brings dealership-level diagnostics into your garage.

Unlike basic code readers that only work with the engine, the Vd70s covers multiple systems. It can check your ABS, airbag (SRS), transmission, and even the electronic throttle control. That means you get a full picture of your vehicle’s health, not just a single snapshot. And with its compact design and easy-to-use interface, it’s perfect for both home use and on-the-go troubleshooting.

Why Choose the Vdiagtool Vd70s Over Other Scanners?

With so many OBD2 scanners on the market, it’s natural to wonder: what makes the Vd70s stand out? The answer lies in its balance of features, usability, and affordability. While some scanners are too basic and others are overly complex and expensive, the Vd70s hits the sweet spot.

First, it’s incredibly user-friendly. The 4.3-inch color LCD screen displays information clearly, and the menu system is intuitive. You don’t need a computer science degree to figure it out. Just plug it into your OBD2 port—usually located under the dashboard near the steering wheel—and the tool powers up automatically. Within seconds, it communicates with your vehicle and displays available options.

Another major advantage is its multi-system coverage. Many budget scanners only read engine codes, but the Vd70s goes deeper. It can access the Anti-lock Braking System (ABS), Supplemental Restraint System (SRS), and transmission control module. This is especially useful if you’re dealing with brake issues or airbag warnings. For example, if your ABS light is on, the Vd70s can tell you whether it’s a faulty wheel speed sensor or a hydraulic problem—saving you time and money on guesswork.

Real-World Example: Diagnosing a Brake Warning Light

Let’s say you’re driving and suddenly the ABS and brake warning lights come on. A basic scanner might only show a generic “brake system fault” code. But with the Vd70s, you can dive into the ABS module and see specific codes like “C1234 – Right Front Wheel Speed Sensor Circuit.” That tells you exactly where to look. You can then test the sensor, check the wiring, or replace it—without taking your car to a shop.

Affordability Without Sacrificing Quality

One of the biggest selling points of the Vd70s is its price. You can find it for under $100, which is a steal compared to professional-grade scanners that cost hundreds or even thousands of dollars. Yet, it doesn’t feel cheap. The build quality is solid, with a durable plastic casing and a responsive keypad. It also comes with a protective case and a long OBD2 cable, so you can use it comfortably from the driver’s seat.

Key Features of the Vdiagtool Vd70s

The Vd70s isn’t just another code reader—it’s a full-featured diagnostic tool packed with capabilities that make car troubleshooting faster and more accurate. Let’s break down the most important features that set it apart.

Full System Diagnostics

As mentioned earlier, the Vd70s doesn’t limit itself to the engine. It can access and diagnose multiple vehicle systems, including:

• Engine Control Module (ECM): Reads and clears engine-related trouble codes, monitors fuel system status, and checks for misfires.
• Transmission Control Module (TCM): Identifies shift solenoid issues, transmission temperature problems, and gear ratio faults.
• Anti-lock Braking System (ABS): Detects wheel speed sensor faults, hydraulic pump issues, and brake pressure anomalies.
• Supplemental Restraint System (SRS): Reads airbag codes, checks crash sensor status, and helps reset the system after repairs.
• Electronic Throttle Control (ETC): Monitors throttle position, accelerator pedal sensors, and idle control.

This comprehensive coverage means you can use one tool for almost any diagnostic need. Whether you’re fixing a rough idle, a slipping transmission, or an airbag warning, the Vd70s has you covered.

Real-Time Data and Live Sensor Readings

One of the most powerful features of the Vd70s is its ability to display live data. This means you can watch how your car’s sensors are performing in real time. For example, you can monitor:

• Engine RPM
• Vehicle speed
• Coolant temperature
• Intake air temperature
• Fuel pressure
• Short-term and long-term fuel trims
• Oxygen sensor voltages

This is incredibly useful for diagnosing intermittent problems. Let’s say your car stalls at idle. A static code might not tell you much, but watching the live data can reveal that the idle air control valve is fluctuating wildly or that a fuel trim is way out of range. You can even graph the data to spot trends over time.

Free Lifetime Software Updates

Technology evolves fast, and so do cars. New models come out every year with updated software and new diagnostic protocols. The good news? The Vd70s supports free lifetime updates. You can connect it to your computer via USB and download the latest firmware and vehicle coverage from the Vdiagtool website.

This ensures your scanner stays relevant for years. You won’t have to buy a new tool every time a new car hits the market. It’s a smart long-term investment.

Large, Easy-to-Read Display

The 4.3-inch color screen is one of the best in its class. It’s bright, clear, and easy to read even in direct sunlight. The interface uses simple icons and menus, so you can navigate without confusion. Codes are displayed with both the number (like P0301) and a plain-English description (“Cylinder 1 Misfire Detected”). This helps you understand the issue without needing a repair manual.

Built-in DTC Lookup Library

Even if you’re not a mechanic, the Vd70s helps you understand what the codes mean. It includes a built-in database of over 3,000 trouble codes with detailed explanations. So when you see a code like P0420 (“Catalyst System Efficiency Below Threshold”), the tool will tell you it’s likely a failing catalytic converter or oxygen sensor. It may even suggest possible causes and solutions.

How to Use the Vdiagtool Vd70s: A Step-by-Step Guide

Using the Vd70s is straightforward, even if you’ve never used a scan tool before. Here’s a simple guide to get you started.

Step 1: Locate the OBD2 Port

The OBD2 port is usually found under the dashboard on the driver’s side. It’s a 16-pin connector that looks like a trapezoid. In most cars, it’s within arm’s reach of the steering wheel. If you can’t find it, check your owner’s manual or look near the fuse box.

Step 2: Plug In the Scanner

Turn off the ignition, then plug the Vd70s into the OBD2 port. The tool will power on automatically. Wait a few seconds for it to establish communication with your vehicle.

Step 3: Turn On the Ignition

Turn the key to the “ON” position (but don’t start the engine). This powers up the vehicle’s computer systems so the scanner can read data.

Step 4: Select Your Vehicle

The Vd70s will prompt you to select your vehicle’s make, model, and year. This ensures accurate diagnostics. Use the arrow keys to navigate and press “OK” to confirm.

Step 5: Choose a Diagnostic Function

Once connected, you’ll see a menu with options like:

• Read Codes
• Clear Codes
• Live Data
• System Tests
• View Freeze Frame

Select “Read Codes” to see any stored trouble codes. The tool will display them with descriptions. If there are no codes, it will say “No Fault Codes Found.”

Step 6: Interpret the Results

Review the codes and their meanings. Use the built-in library or search online for more details. If you’re unsure, take a screenshot or write down the code for reference.

Step 7: Clear Codes (If Needed)

After fixing the issue, return to the menu and select “Clear Codes.” This resets the check engine light and erases stored fault codes. Note: clearing codes doesn’t fix the problem—it just resets the system. Make sure the issue is resolved first.

Step 8: View Live Data

To monitor real-time performance, select “Live Data.” Choose the sensors you want to watch. You can view them individually or in a graph format. This is great for testing repairs or diagnosing intermittent issues.

Pro Tip: Use Freeze Frame Data

The “Freeze Frame” feature captures a snapshot of your vehicle’s conditions at the moment a fault occurred. It shows things like engine speed, load, temperature, and speed. This can help you understand what triggered the code—like a misfire during acceleration or a sensor failure at idle.
