Topdon AD500S OBD2扫描仪评论（代码阅读器扫描工具）

回到过去，诊断汽车麻烦纯粹是一个机械过程。所有零件都是机械的，任何计算机都小而简单。亚洲官方合作伙伴最糟糕的是，您必须拿出电压表才能诊断电气问题。

But nowadays, a lot of your car’s systems are controlled by sensors and computers. The engine control unit (ECU) and transmission control unit (TCU), are both good examples of this. They control everything from your timing to your fuel to gas ratio.

This is great news for fuel efficiency. These days, you can get a lot more power from a lot less fuel than you could a few decades ago. But it can make your car difficult to service. Instead of a timing belt and carburetor, you’re trying to figure out if there’s a computer glitch. Thankfully, manufacturers are well aware of this issue.

Since way back in 1996, cars have used on-board diagnostic (OBD) ports to allow for easy communications. With an OBD2 scanner, you can read any error codes your car is putting out, and decipher what they mean.

如果您看到任何仪表板指示灯，读取诊断代码也很重要。假设您获得了可怕的“检查引擎”灯；那可能意味着任何数量的事情。如果您甚至要开始解决问题，则需要阅读您的代码。这会告诉您问题所在的位置，因此您可以采取适当的措施。

Topdon AD500S OBD2扫描仪

We’re about to review theTopdon AD500S OBD2扫描仪。Topdon是一家以质量声誉的制造商，在几个垂直方面提供了产品。这款OBD2扫描仪看起来非常坚固，电子设备是最新的。更好的是，您可以通过WiFi获得免费的固件更新。

But there are many things that go into making a good quality scanner. We’ll have to talk about how it works, and how it’s operated. We’ll need to go over the scanning capabilities, as well as its resetting features. And we’ll need to address what vehicles it’s even compatible with. Let’s begin!

Overall Design

The first thing you’ll notice about theTopdon AD500S OBD2扫描仪is how beefy it is. The 5-inch touchscreen display could be housed in a much smaller device, but then it would be vulnerable. Instead, TOPDON opted for a fatter, chunkier design, with a fat black plastic housing. The edge is nice and fat, so even if you drop it on its face, the screen won’t get damaged. Just inside of the edge, there’s a set of little textured silicone grips. That way, it’s still easy to hold on to. All in all, this is a tough, shop-ready tool.

The OBD2 cable connects at the top center of the housing. The cable is nice and thick, with plenty of insulation and protection. It’s reinforced where it meets the housing, with a thick rubber collar that extends a ways up the wire. The other end of the cable is also reinforced where it meets the plug, so it’s tough enough to take a beating.

AD500是电池供电的，并且一次充电可以一次运行几个小时。该套件包括USB Type-C电缆，可插入底部以进行充电。充电是快速而无痛的。而且，如果这是一个日常工具，则可以在不使用时将其插入。

Topdon采用12个月的制造商保修，支持该扫描仪。如果过早失败，您将获得退款或更换。不仅如此，他们提供了60天的无条件退货政策。如果事实证明您不喜欢扫描仪，则可以将其发送回。

如果您正在寻找更实惠的东西，请查看INNOVA CarScan Advisor 5210。It’s half the price, and it has a curved, ergonomic shape with big rubbery buttons. Then again, it lacks some more advanced features, such as an SRS (airbag) scan.

Basic Operation

Operating theAD500S很简单。菜单导航,there’s a set of navigational arrows to the right. There’s also an “OK” button above them, for selecting options, and a back button for backing up. All the buttons are big, black, and chunky, easy to operate even if you’re wearing a set of gloves.

Then again, it’s even easier to work without gloves. The touchscreen has a tiled layout, and you can use it to quickly navigate from one menu to another. This is the simplest way to perform many of the scanner’s functions.

The internal hardware is up to date, so navigation is seamless and lag-free. It doesn’t hang during operations like a lot of older scanners. Not only that, but the Android 6.0 operating system is exceptionally lightweight. As a result, startup is nearly instantaneous. When you first plug it into your car, it will automatically scan for the VIN, and detect your car’s model. This saves you the effort of manually entering your VIN number during setup.

在系统本身中，您可以查找触发的任何代码。这使得很容易找出这些四位数代码的实际含义。如果您仍然感到困惑，Topdon将提供对所有代码的专家反馈的在线社区的访问权限。

If English isn’t your primary language, you don’t have to worry. The display supports nine different languages: English, French, German, Italian, Japanese, Korean, Portuguese, Russian, and Spanish. You can also make paper records of your scans. Just connect to any Windows PC, and you’ll be able to print off any data you’ve recorded to memory.

它读了什么？

Ultimately, an OBD scanner is only as good as the codes it can read. Some scanners are only able to read certain types of codes, which limits their performance. Here’s a quick look at what you can do with the AD500S.

• Engine scanning– You can read and clear both permanent and pending engine codes. This includes codes related to fuel injection, emissions, timing, and more. This covers the vast majority of issues that trigger a Check Engine warning.
• 防锁制动（ABS）扫描– You can read and clear error codes in the ABS system, which will normally clear the ABS light. You can also look up real-time data on your car’s performance, including individual sensors. This can help you identify faulty sensors, or determine whether there’s a real safety issue. If necessary, you can then repair your brakes, or replace the faulty sensor.
• Transmission scanning– Most Check Engine light-related issues that aren’t caused by the engine are caused by the transmission. This makes sense, since the two are integral parts of your car’s powertrain system. You can read and clear these codes, as well as view diagnostic data. If your car is struggling in a particular gear or having trouble shifting, you’ll be able to tell.
• 安全气囊（SRS）扫描– Your airbag sensors are often the only warning you’ll have of a critical safety failure. A lot of scanners don’t read SRS codes, which can make airbag problems notoriously hard to diagnose. With an SRS scanner, you can locate the source of the problem and perform any needed repairs. You can also clear the codes to deactivate your warning light.

Extra Features

OBD2扫描仪不仅是阅读代码所必需的。您的汽车的OBD2端口是重置一些平凡灯的唯一方法，否则可能会使您失败。以下是AD500旨在提供帮助的五种方式：

• Oil light reset (works with 53 car manufacturers)- 许多现代汽车都有数字油指示器和警告灯。当这些灯告诉您是时候进行换油的时候，即使在更改之后，它们也不会总是关闭。在这种情况下，您可以使用此扫描仪手动重置光线。这也将重置任何传感器，因此您知道下次光线将正常工作。
• BMS重置（与31个汽车制造商一起使用）– As your battery ages, your car’s battery management system (BMS) changes how it draws power. When you install a new battery, a BMS reset forces the BMS to treat it as new, not old.
• ABS出血（与34家汽车制造商一起工作）- 类似于换油后的油灯类似，ABS流血后可能会保留ABS的光线。将其重置以将其返回正常。
• 油门适应（与37个汽车制造商一起使用）– If your throttle actuators are defective, they could be kicking in or easing up too slowly. Tweaking these settings can give you smoother acceleration.
• DPF regeneration (works with 39 manufacturers)– Most drivers won’t have to deal with this. But if you’re driving a diesel car or truck, you’ll have to periodically regenerate your diesel particulate filter. This is how it’s done.

Vehicle Compatibility

TheTopdon AD500S OBD2扫描仪works with most vehicles produced since 1996. More specifically, it works with any car or truck that uses the OBD2, EOBD, JOBD, or CAN protocol. This includes not just passenger vehicles, but many light trucks. However, it doesn’t support larger, 24-volt diesel trucks. Check with your manufacturer to be sure.

开箱即用，这款扫描仪支持在2020年型号的年度内支持模型。但是，您可以通过将其连接到WiFi来免费获得更新。这是一项免费的终身服务，因此您将继续获得新车辆的扫描能力。随着新功能的添加，您将可以在不购买新扫描仪的情况下访问这些功能。

Final Verdict

TheTopdon AD500S OBD2扫描仪是一台高度能力的机器。有点贵，但这是因为它提供了很多功能。如果您需要真正的可购物扫描仪，您将感谢所有额外的重置功能。即使对于普通驱动程序，无线更新也提供了大量的附加值。
