使用活塞，您的汽车的诊断信息触手可及。检查引擎灯 (MIL) 是否亮起？使用 Piston 将您的移动设备变成汽车扫描仪，并读取与问题相关的诊断故障代码 (DTC) 以及冻结帧数据。这将帮助您识别和解决问题。
您将需要一个基于 ELM 327 的适配器（蓝牙或 WiFi），将其连接到车辆中的 OBD2 插座。活塞将引导您完成连接过程。您可以在首次安装后从主页访问说明，也可以随时从设置访问说明。
使用活塞，您可以：
• 读取并清除 OBD2 标准定义的诊断故障代码 (DTC)
• 查看冻结帧数据（ECU 检测到故障时传感器数据的快照）
• 实时访问传感器数据
• 检查就绪监测器（监测排放控制装置）的状态
• 将您阅读的 DTC 存储在本地历史记录中
• 登录并将您阅读的 DTC 保存在云端
• 访问传感器读数的图表
• 将实时数据从传感器导出到文件
• 检查你的车的VIN号码
• 检查 ECU 的详细信息，例如 OBD 协议或 PID 编号
以上一些是高级功能，需要一次应用内购买才能解锁所有功能。没有订阅！
这个应用程序，为了成为一个汽车扫描仪，需要一个单独的基于 ELM327 的设备，蓝牙或 WiFi。活塞与 OBD-II（也称为 OBDII 或 OBD2）和 EOBD 标准兼容。
从 1996 年起在美国销售的所有车辆都必须支持 OBD2 标准。
在欧盟，从 2001 年开始对汽油发动机车辆和从 2004 年开始对柴油车辆强制执行 EOBD。对于澳大利亚和新西兰，所有 2006 年生产的汽油车和 2007 年生产的柴油车都需要 OBD2。
重要提示：此应用程序只能访问您的车辆通过 OBD2 标准支持和提供的数据。

Of all OBD2 apps available on the play store, this is the one I've settled on. Take that for whatever it's worth, extra star for including a 7$ One-Time purchase for features that other apps would require a subscription for. Isn't the most feature-filled, but what's here is sold and it's a cleaner UX than most apps I've tried, which feel.. rushed.

Connects but won't read any live data from my Elm327 Bluetooth dongle, which works fine with both Car Scanner and Torque Lite. Car is a 2013 Honda CR-V. Very disappointed. ** UPDATE ** My bad. I didn't notice the "Play/Pause" icon on the live data screen. Pressing "Play" resulted in the display of the data. My apologies to the developer. Changed rating to 4 stars for now. Will update after further testing.

After having tried many of the popular OBDII apps, this is the one I stuck with. Clean interface, the UI is simple to navigate, and no irritating ads. Connected quickly to my BAFX Bluetooth scanner and easily cleared and found issues. 4 stars given for inability to locate MAP sensor issue, but to be fair, similar apps did not find the issue either.

App has a simple interface, and is ad-free which is nice, but it's extremely limited in the number of PID's that it can read. All of the supported PID's are related to the ICE. There is no support that I could find for Hybrid system functions like traction battery state of charge, battery/inverter temperature, or power flow. This app is of little use to owners of hybrid vehicles, unfortunately. It's not a bad app, just too limited for what I need for a Prius PHEV.

This App was great until the recent update, now it's a big effort to get the app to connect to EM327 dongle, and what was once a simple to navigate and understand interface now requires a lot more concentration that it should. No longer as user friendly and simple to use, so harder to recommend to non-tech friends.

This app has served me well for so long... and continues to do so. I bought premium, as the price is great for value, and functionality (especially logging) is superb. Interface is clean, and easy to navigate. Best OBD reading app for me.

Just started using, having trouble figuring it out. Instructions would be nice. I have no check engine light lit up or code at the moment on my truck, maybe that's the problem. Scanned for faults and it just sits there. Seems like is should say no codes found. The function buttons at top of screen are not labled.

Great app, liked the cleaner interface before the 2023 update but it still works well. I'd give five stars if it displayed on Android Auto so I didn't have to grab my phone to see real-time data while driving.
