Monitor live sensor values with real-time graphs. Check engine RPM, fuel trim, coolant temp, and more. Spot issues early and understand your vehicle’s performance at a glance.

No need to pop the hood, no clamps, simply plug into the OBD-II port.

Note: Incompatible with hybrid or electric vehicles. Is this OBD2 scanner compatible with my vehicle? It is compatible with most cars built after 1996 (US), 2001 (EU) and 2008 (Asia) that are equipped with an OBD2 port. But it is not compatible with new energy vehicles, hybrid vehicles, and models that do not comply with the OBD2 protocol. How to connect OBD2 scanner with vehicle and read/clear code? 1. Turn off ignition, connect the code reader to the car. 2. Turn on ignition, the car scanner will automatically connect to your car. 3. Start engine, press F1 and it will automatically read the fault codes, then press the OK button to clear. Does the scanner support proprietary protocols such as SRS, ABS, TPMS? Sorry, this OBD2 does not have these functions. Its main function is to diagnose the vehicle's engine system, identify fault codes and clear them. Why I need an OBDII scanner? It can diagnose and clear error codes, monitor various sensor data, reset engine light, DIY repairs and retrofits, and more. You can pinpoint the root cause of problems and fix them without unnecessary expense. Why OBD2 Scanner Cannot Clear the DTC? OBD2 scanner can clear temporary trouble codes by itself. But if it is a persistent fault, after repairing the fault, drive for a period of time or perform a specific driving cycle to meet the clearing conditions. Note: ZM201 only supports engine system diagnostics and does not support proprietary protocols such as SRS, ABS, and TPMS etc.

Check engine? No problem! Easy, handy, and saves time & money 🚗✅
Color: yellow
I got this for our 2018 Nissan Sentra when the check engine light popped on, and I’m so glad I did! I had been thinking about getting one for a while, but that little warning light pushed me over the edge. Having this at home is a total game-changer—I no longer have to run to the auto parts store or wait on a mechanic just to see what’s going on. It’s incredibly easy to use and understand, even for someone who isn’t super car-savvy. I love that I can read codes, reset them, and even check live data without leaving the driveway. It’s already saved us time and money, and the neighbors love borrowing it too! Some things I really like: Clear, easy-to-read 2.8” color screen with dark/light modes Can read and reset codes for almost any car after 1996 Built-in 35,901 DTCs—way more than older models Live data and graphs, plus the option to print results Audible notifications and handy shortcut buttons make it simple This scanner is a must-have if you want to take a little control over your car repairs and avoid unnecessary trips to the shop. Highly recommend! ... show more

Decent Value
Color: yellow
Its good, for the price. Does good at reading/clearing engine codes and reading generic OBD data, so if that's all you need, works just fine.

Works OK if it is compatible with a vehicle. However, I find that there are many vehicles it is not compatible with.
