Learn how to reset the oil service light on a Kia Pegas or Soluto using a LAUNCH X431 scanner. Quick 5-minute procedure with troubleshooting tips.

Quick Answer

To reset the oil service light on a Kia Pegas or Soluto using a LAUNCH X431 scanner, connect the tool to the OBD2 port, select your vehicle from the Kia menu, navigate to the Oil Reset service function, and follow the on-screen prompts. The entire process takes under five minutes and requires no special tools beyond the scanner.

Why Reset the Oil Service Light?

The oil service light isn’t just an annoying dashboard reminder—it plays a practical role in vehicle maintenance. Here’s why resetting it matters:

  • Indicates scheduled maintenance is due – The light triggers based on mileage or time intervals, not actual oil condition. After an oil change, resetting it ensures the system tracks the next service correctly.
  • Prevents confusion – If the light stays on, it’s easy to forget whether the oil was actually changed, especially in a multi-driver household or fleet vehicle.
  • Required for accurate reminders – Leaving the light on means the onboard computer won’t alert you when the next oil change is actually needed. You could end up over- or under-servicing the engine.

Before You Start

Before diving into the reset procedure, take care of these prerequisites:

  • Park safely – Ensure the Kia Pegas/Soluto is on a level surface with the engine off. You may need the ignition ON (engine off) for some steps.
  • Check the LAUNCH X431 – Confirm the device is charged or connected to a power source. A low battery mid-procedure can interrupt communication with the ECU.
  • Update the software – Always update your LAUNCH scanner to the latest firmware and vehicle software. Kia models are well-supported, but an outdated version may miss the Oil Reset menu.
  • Verify compatibility – LAUNCH X431 series tools (X431 V+, X431 HD, X431 Pro, X431 PAD VII, etc.) work with Kia Pegas/Soluto from 2017 onward. If you have an older X431, check the supported vehicle list.

Step‑by‑Step Procedure

1. Connect the LAUNCH X431 Scanner

  • Locate the OBD2 port under the driver’s side dashboard. It’s typically near the fuse panel or just above the hood release lever.
  • Plug the main diagnostic cable into the port. The scanner should power on automatically.
  • Turn the ignition to the ON position (engine off). The dashboard lights should illuminate.

2. Launch the Diagnostic Software

  • On the LAUNCH X431 home screen, tap Diagnostics.
  • From the brand list, select Kia.
  • The scanner will begin establishing communication with the vehicle’s ECU. This usually takes 10–20 seconds.

3. Select the Vehicle Model

  • Choose Pegas from the model list. In some markets, it may appear as Soluto (the hatchback variant). Both share the same platform, so the procedure is identical.
  • Confirm the model year and engine type (typically 1.4L MPI for Pegas, 1.4L for Soluto).
  • Wait for the system to read the vehicle information. A successful connection shows the VIN and current ECU data.

4. Access the Oil Reset Service

  • From the main diagnostic menu, tap Service or Maintenance (depending on your LAUNCH X431 version).
  • Scroll down to Oil Reset or Oil Service Reset.
  • On some LAUNCH models, this function sits under Special Functions. If you don’t see it immediately, tap the “More” button or use the search bar.

5. Execute the Reset

  • Read the on-screen instructions carefully. The scanner may ask you to “Turn ignition OFF for 30 seconds, then back ON” before proceeding.
  • Follow the prompts:
    • The tool may display the current oil life percentage (e.g., 15%). Tap Reset or Yes to set it to 100%.
    • Some versions require confirming the oil type or mileage since last change.
    • Wait for the confirmation message: “Reset successful”.
  • If the procedure pauses, ensure the ignition stays in the ON position. A common mistake is accidentally turning the key to ACC.

6. Verify the Reset

  • Turn the ignition OFF, then start the engine.
  • The oil service warning light should be off. If it remains on, repeat the procedure or check for pending diagnostic trouble codes (DTCs). Clear any stored codes that might interfere with the reset.

Troubleshooting Common Issues

Problem Possible Cause Solution
Scanner cannot find the vehicle Incompatible adapter or outdated software Update LAUNCH firmware; try a different OBD2 cable; use AutoVIN scan
Oil Reset menu missing Vehicle not supported or wrong model selection Double-check model year; manually enter VIN; select a different variant (e.g., Soluto instead of Pegas)
Reset fails with “Operation not completed” Ignition state incorrect or battery voltage low Ensure ignition is ON; connect a battery maintainer if voltage is below 12V
Light returns after a few starts Reset not saved or internal system error Perform the procedure again; clear all DTCs before resetting; check for aftermarket accessories that may interfere

Deeper Context: Oil Service Reset on Kia Pegas/Soluto

Why the LAUNCH X431?
The LAUNCH X431 series covers Asian vehicles exceptionally well, includes guided reset routines, and costs significantly less than dealer-level tools like GDS or KDS. For a home mechanic or small workshop, it’s the perfect balance of capability and price.

Alternative methods:

  • Steering wheel button reset – Some Kia models allow resetting via the trip button (ignition ON, press and hold Trip for 10 seconds, then turn ignition OFF and restart). However, this method doesn’t work on all Pegas/Soluto trims, especially post-2020 models.
  • Generic OBD2 apps – Apps like Car Scanner or Torque Pro can read and reset oil life if your ELM327 adapter supports Kia protocols. But these often lack the guided service routines, making the process less reliable.

I’ve found that the LAUNCH scanner is the most straightforward tool for this job. It walks you through every step and rarely fails if the prerequisites are met.

Important notes:

  • Do not reset the oil light without actually changing the oil and filter. Resetting it without a change will cause the system to miscalculate future intervals, leading to contamination and potential engine wear.
  • The reset procedure is identical for the Pegas (sedan) and Soluto (hatchback)—they share the same chassis and ECU logic.
  • Some LAUNCH X431 models require an internet connection the first time you use the service function to download the correct reset routine. Ensure WiFi or a mobile hotspot is available.

Frequently Asked Questions

Can I reset the oil service light without a scanner?
In some Kia Pegas/Soluto models, you can try a manual method: turn ignition ON, press the trip reset button for 10 seconds, then turn ignition OFF and restart. However, this does not work on all years—especially newer ones. A LAUNCH X431 is the recommended tool for guaranteed success.

Will resetting the oil light affect my car’s warranty?
No, performing a service reset with a professional scanner like the LAUNCH X431 is a standard maintenance procedure and does not void the warranty. Dealerships and workshops use similar tools daily.

How often should the oil service light come on?
Typically every 12 months or 10,000 km (6,000 miles) for Kia Pegas/Soluto, depending on driving conditions. If you drive in severe conditions (dusty roads, frequent short trips, extreme temperatures), the interval may be shorter—refer to your owner’s manual.

My LAUNCH X431 cannot find the “Oil Reset” option. What should I do?
Update the scanner software, then re-enter diagnostics. If still missing, try selecting a different model year or use the AutoVIN scan to automatically detect the vehicle. Sometimes the option is hidden under Special Functions > Oil Reset Service.

Is it safe to drive with the oil service light on?
Yes, the light is only a reminder. It does not indicate low oil pressure. However, you should schedule an oil change promptly to avoid missing the service interval and causing engine wear.

Can I use a LAUNCH X431 on other Kia models?
Absolutely – the X431 supports all Kia models (e.g., Rio, Cerato, Sorento, Sportage) with similar oil reset procedures. For more details, check out our article on [link to related guide on other Kia model oil reset].

What if the reset button on the scanner is grayed out?
This usually happens when the vehicle’s ECU is not ready. Turn the ignition OFF for 30 seconds, turn it back ON, and try again. If it persists, check for pending diagnostic trouble codes and clear them first before attempting the reset. For more troubleshooting, see [link to related guide on LAUNCH X431 common issues].
