Best for DIY owners who want a simple, reliable phone‑paired scanner to read/clear codes and reset oil/service lights with a top‑rated, no‑subscription app; not aimed at niche manufacturer coding.
Best when you need advanced maintenance and manufacturer‑specific resets (oil, EPB, throttle adaptation, steering angle) — more capable for repair tasks but likely overkill for simple light clearing.
Best for budget buyers who will accept extra setup: the cheapest phone‑paired OBD‑II adapter running a Car Scanner app can clear service lights but yields variable compatibility and user experience.

If your goal is plug it into the OBD-II port, pair it with your phone, and reset service/maintenance lights, I’d look at these:
$51.99
The TOPDON TopScan Lite is a particularly good fit. It connects to iPhone/Android over Bluetooth and supports Oil Reset, EPB (electronic parking brake) reset, steering-angle reset, DPF regeneration, ABS bleeding, BMS reset, and airbag reset. TOPDON says it covers 120+ vehicle makes.
If you want more capability, TopScan Pro adds things such as TPMS reset, injector coding, window calibration, and seat/sunroof functions.
$99.00
Important: service-reset capability is vehicle-specific. A scanner may support an oil reset on one model but not another.
If you tell me your year, make, model, and engine (e.g. 2021 Honda CR-V 1.5T), I can tell you exactly which phone-connected scanner I'd buy and which service lights it can reset.
To reset service lights (like oil life, maintenance reminders, or electronic parking brakes) using your smartphone, a basic $15 generic code reader won't work . You need an enhanced Bluetooth OBD2 adapter paired with an app that supports full-system diagnostics and special maintenance resets.
The best options depending on your budget and vehicle make include:
To narrow down the absolute best fit, tell me:
Yes. What you want is a Bluetooth OBD-II scanner that connects to an iPhone or Android phone. The important distinction is that “clear codes” and “reset service lights” aren't always the same thing—oil/service, ABS, airbag, TPMS, and maintenance resets may require more advanced vehicle-specific functions.
$119.99
$51.99
$94.98
$59.99
Best overall for service resets: ANCEL ECHO — about $120. It offers full-system diagnostics and specifically advertises oil, battery-management and brake resets, with iOS/Android support.
Best value: TOPDON TopScan Lite — about $52. It connects to your phone and adds bidirectional functions, making it considerably more capable than a basic code reader.
Best simple option: FIXD — very easy to use from your phone, but I'd choose it primarily for check-engine diagnostics rather than broad service-reset capability.
Avoid if resets are your main goal: ANCEL BD310. It's an excellent inexpensive phone-connected scanner, but it's primarily an OBD-II reader and doesn't offer the broad service-reset functions you're asking for.
One important caveat: the exact resets depend on the vehicle. If you tell me your year, make, model, and engine (e.g. 2021 Ford F-150 5.0), I can tell you which phone-connected scanner will actually reset the service light on your car, rather than just clear the check-engine code.
To reset service lights (like oil life, maintenance reminders, or electronic parking brake modes) using your phone, standard cheap $10 generic code readers won't work . You need a Bluetooth Low Energy (BLE) dongle paired with an app that supports enhanced diagnostics and service resets.
The best options on the market depend on your budget and how deep you want to go into diagnostics:
Topdon TopScan — A pocket-sized Bluetooth dongle that turns your iOS or Android phone into an advanced tool. The hardware is affordable ($50–$60 for the Lite version) and supports full-system diagnostics and multiple service resets (oil maintenance reset, EPB, etc.). It features quick pairing and a robust app interface.
OBDLink MX+ — Widely considered the gold standard for reliable smartphone diagnostics. It costs more (around $140), but it supports a massive array of manufacturer-specific protocols, works seamlessly on both iPhone and Android, and doesn't rely on sneaky recurring subscriptions for basic diagnostics and supported reset functions.
Carista OBD2 — Great if you drive a European or modern vehicle and want to customize features (coding) alongside resetting service lights. The adapter is reasonably priced, though full access to advanced service resets and customization in their app requires an in-app subscription (often a weekly or annual fee).
Veepeak OBDCheck BLE — The best budget entry-point (around $30). While standard apps like Torque Pro or basic Car Scanner ELM OBD2 mostly just clear check engine (DTC) codes, pairing the Veepeak with advanced third-party apps like OBDocker can unlock oil resets and basic maintenance light clearances on many mainstream vehicle models without breaking the bank.
To help narrow down the ideal choice, what is the year, make, and model of your car, and are you using an iPhone or Android?
To reset service lights (like oil life, maintenance reminders, EPB, or battery registration) using your phone, a generic $15 ELM327 Bluetooth adapter won't be enough . Standard generic adapters only read/clear basic engine emission codes (Check Engine Light)—they cannot talk to the specific modules responsible for service intervals.
You need a bi-directional or enhanced diagnostic Bluetooth dongle that pairs with a capable app on iOS or Android.

A few highly regarded phone-based scanners that are widely recommended by reviewers include the BlueDriver, OBDLink MX+, and TOPDON TopScan Lite, all of which offer stronger app experiences and broader vehicle support than generic ELM327 adapters.
One important question: What is the year, make, and model of your vehicle? Some manufacturers allow service-light resets with nearly any capable scanner, while others require brand-specific support. With your vehicle information, I can recommend the most compatible tool.
If your goal is to pair with your phone and reset service lights (such as oil service reminders), you'll generally want more than a basic code reader. Many inexpensive Bluetooth adapters can clear check engine lights, but service/maintenance resets often require manufacturer-specific functions.
Here are some good options:
$79.99
This is a good value if you want:
Other solid choices:
$49.99
Good for reading/clearing codes, live data, and basic diagnostics through a smartphone app.
$149.00
A more advanced option with bidirectional controls and expanded service functions for users who do more of their own maintenance.
If you only need to read and clear engine codes, a budget adapter is enough:
$31.98
Just keep in mind that adapters in this class typically won't reset all manufacturer-specific service reminders.
To recommend the right scanner, tell me:
Some brands (BMW, Volkswagen/Audi, Mercedes, Toyota, etc.) require brand-specific reset functions, so the best tool depends on the vehicle.
To reset service lights (like oil life, maintenance reminders, or electronic parking brake service modes) using your phone, basic $15 generic code readers won't work , as they only handle engine emission codes. You need an enhanced Bluetooth dongle that pairs with a capable app to access manufacturer-specific maintenance resets.
Top smartphone-paired diagnostic tools capable of resetting service lights include:
An affordable wireless option that plugs into your OBD2 port and connects via Bluetooth 5.0 to iOS and Android. It offers full-system diagnostics and multiple built-in maintenance reset functions (including oil light resets, electronic parking brake, and DPF regeneration).
A popular Bluetooth adapter that turns your phone into an advanced diagnostic system. It includes one vehicle brand-specific software package with free updates and supports roughly 19 different maintenance and reset functions, including oil service resets and EPB calibration.
A powerful DIY-to-professional level Bluetooth dongle. It pairs with your phone to provide full system diagnostics and over 20 specialized maintenance reset capabilities (oil reset, steering angle, throttle relearn, ABS bleeding) with extensive vehicle coverage.
A highly reliable, subscription-free option for iOS and Android. Note: While it reads and clears enhanced codes brilliantly and gives verified repair reports, its native app support for deep service/oil light resets can be limited depending on the specific vehicle make compared to dedicated reset scanners like Autel or Topdon.
If you share your car's make, model, and year , I can check which of these tools has the best direct compatibility for your specific service reset procedures.
Based on your need to reset service lights using a phone, the best tools are Bluetooth-enabled OBD2 scanners that provide "special functions" or "maintenance resets."

Key Features to Look For
To provide a more tailored recommendation, are you looking for a one-time fix for a specific car (e.g., oil light), or do you need a tool for ongoing, complex maintenance on multiple vehicles?
If you want a Bluetooth car diagnostic tool that connects to your phone and can reset service lights, look for more than a basic “check engine code reader.” Many cheap OBD2 adapters can only read/clear engine codes; oil/service resets, ABS, airbag, EPB, battery registration, TPMS, and other maintenance functions require a more capable scanner and depend on your vehicle.
Here are some good options:
