The Check Engine light on your car is both useful and infuriating. You know something is wrong (which is good!), but you don’t know what. Rather than taking your car all the way down to your mechanic, you can get a pretty good idea what’s wrong with your car with a simple OBD-II adapter.
汽车上的Check Engine指示灯既有用又令人发指。 您知道有什么问题(很好！)，但您不知道什么。 通过简单的OBD-II适配器 ，您可以很好地了解汽车出了什么问题，而不是将汽车一直带到修理工那里。
Every car sold in the US after 1996 has an OBD-II port that you can use to connect your car to your phone. This is the same port that a mechanic will connect to in order to find out what’s wrong with your car when the Check Engine light comes on. For a long time, you needed special hardware to use it, but cheap Bluetooth OBD-II adapters (and your cell phone) have made it easy to do it yourself.
1996年以后在美国销售的每辆汽车都具有OBD-II端口，您可以使用该端口将汽车连接到手机 。 这是技工将连接到的端口，以便在Check Engine指示灯点亮时找出您的汽车出了什么问题。 长期以来，您需要特殊的硬件才能使用它，但是便宜的蓝牙OBD-II适配器 (和您的手机)使您自己轻松实现这一目标。
There are several ways to diagnose your check engine light, but we’re going to use an app called Dash. This app lets you store important information about your car, track your driving and, as a bonus, diagnose check engine lights. It’s available for Android and iOS, so download it before moving on. If you’ve never used an OBD-II adapter before, check out our guide here to get set up.
有几种方法可以诊断您的检查引擎指示灯，但是我们将使用一个名为Dash的应用程序。 该应用程序可让您存储有关汽车的重要信息 ，跟踪驾驶情况以及作为诊断检查引擎灯的奖励。 它适用于Android和iOS ，因此请先下载它。 如果您以前从未使用过OBD-II适配器， 请在此处查看我们的指南进行设置 。
Turn on your car and let your OBD-II adapter pair to your phone. Open your Dash app and tap the car icon along the bottom to open your Garage.
打开汽车，让OBD-II适配器与手机配对。 打开您的Dash应用程序，然后点击底部的汽车图标以打开您的车库。
Scroll to find the car you’re connected to right now (if you have more than one), then tap on it.
滚动查找当前连接到的汽车(如果有多个)，然后点击它。
Underneath the picture of your car (if you have one), tap the Engine Alerts button.
在您的汽车图片下方(如果有的话)，点击引擎警报按钮。
If Dash detects an error code it can diagnose, it will display information about it here. It will also give you an estimate on how much it will cost to fix it. It will even search for mechanic shops in your area that you can take your car to.
如果Dash检测到可以诊断的错误代码，它将在此处显示有关该错误的信息。 它还将为您估计修复它的成本。 它甚至会搜索您所在地区的机械商店，以便您开车上车。
Some error codes that a check engine light can throw may indicate several issues, so this isn’t a foolproof method. Some things you may be able to fix yourself—for example, if you lose your gas cap, you’ll get a check engine light, but replacing a gas cap is easy to fix. If it’s a complicated or delicate repair job, you may be better off taking it to a professional. In that case, Dash can at least help you shop around and find a reasonable price for the job.
检查引擎指示灯可能会抛出的一些错误代码可能表示几个问题，因此这不是万无一失的方法。 您可能可以自行修复某些问题，例如，如果丢失了油门盖，则会看到发动机检查灯，但更换油门盖很容易修复。 如果这是一项复杂或微妙的维修工作，最好将其交给专业人员。 在这种情况下，Dash至少可以帮助您货比三家并找到合理的工作价格。
