OBD2 doesn't have to be complicated
Car Diagnostics Should Be Simple
Traditional OBD2 apps can feel like tools made for technicians: dozens of menus, dashboards, gauges, settings and protocols.
OBD2: Check Engine Reset is built around the thing most drivers actually want to do when the warning light appears: connect to the car, diagnose the Check Engine Light and reset it.
The app handles the technical connection process behind the scenes so you can focus on the diagnostic result instead of configuring OBD protocols.
One app. One scanner. One straightforward workflow.
How it works
Diagnose Your Check Engine Light in 3 Steps
-
Connect Your OBD2 Scanner
Plug a compatible OBD2 or ELM327 adapter into your vehicle's diagnostic port and connect it to your phone.
The app is designed to work with common Bluetooth, BLE and Wi-Fi OBD2 adapters depending on your device and platform.
-
Diagnose the Vehicle
Open OBD2: Check Engine Reset and let the app communicate with your vehicle.
The app automatically detects the supported OBD2 connection and reads the diagnostic information associated with the Check Engine Light.
No complicated OBD settings. No manual protocol selection.
-
Reset Check Engine
Once the diagnosis is complete, reset the Check Engine Light directly from your phone.
The entire process is designed to be fast, clear and understandable even if you have never used an OBD2 scanner before.
Know What Your Check Engine Light Is Telling You
A Check Engine Light gives you very little information by itself.
An OBD2 diagnostic code gives you something useful.
OBD2: Check Engine Reset communicates with the vehicle through its OBD2 diagnostic system and displays the detected diagnostic trouble code in a simple format.
Instead of looking at an unexplained warning light, you can immediately see the code reported by the vehicle.
The app is intentionally focused on making Check Engine diagnostics easy to access for everyday drivers.
Reset Your Check Engine Light From Your Phone
You do not need a large handheld diagnostic scanner just to access standard Check Engine diagnostics.
With a compatible OBD2 adapter and OBD2: Check Engine Reset, your phone becomes your scanner.
The app removes unnecessary steps so that resetting the Check Engine Light takes only a few simple actions.
Reset Your Check Engine Light
Connect. Diagnose. Reset.
