In this comprehensive guide, you’ll learn several safe and effective ways to reset the engine light on your 2014 Chevy Equinox. We’ll cover everything from using an OBD2 scanner—the most reliable method—to alternative approaches like disconnecting the battery. You’ll also get practical tips, troubleshooting advice, and answers to common questions so you can confidently handle this task at home.

Whether you’re a DIY enthusiast or just trying to save a trip to the mechanic, this guide will walk you through each step with clarity and simplicity. Let’s get started.

Understanding the Check Engine Light

Before jumping into the reset process, it’s important to understand what the check engine light actually means. The light is part of your vehicle’s onboard diagnostics system (OBD2), which monitors engine performance, emissions, and other critical functions. When the system detects a problem—such as a misfire, faulty sensor, or emissions leak—it triggers the check engine light and stores a diagnostic trouble code (DTC).

These codes are standardized across all vehicles, so a P0420 code, for example, means “Catalyst System Efficiency Below Threshold” and is the same whether you drive a Chevy Equinox or a Toyota Camry. The 2014 Chevy Equinox uses the OBD2 system, which has been mandatory in all vehicles since 1996.

It’s crucial to note that the check engine light doesn’t always mean a major repair is needed. Sometimes, it’s as simple as a loose gas cap. Other times, it could indicate a serious issue like a failing catalytic converter or engine misfire. That’s why diagnosing the problem before resetting the light is essential.

Ignoring the light or resetting it without fixing the root cause can lead to decreased fuel efficiency, increased emissions, and even engine damage over time. So, always start by identifying the issue.

Tools You’ll Need

To reset the engine light on your 2014 Chevy Equinox, you’ll need a few basic tools. The good news is that most of these are affordable and easy to find.

OBD2 Scanner

The most effective and recommended tool is an OBD2 scanner. This device plugs into your vehicle’s diagnostic port and communicates with the onboard computer to read trouble codes and reset the check engine light. Look for a scanner that includes a “clear codes” or “reset” function. Basic models start around $20, while more advanced ones with live data and Bluetooth connectivity can cost $100 or more.

Owner’s Manual

Your vehicle’s owner’s manual can provide specific information about the diagnostic port location, fuse box, and recommended procedures. It’s always a good idea to keep it handy.

Pen and Paper (Optional)

If you’re reading codes manually or noting down information, having something to write with can be helpful.

Step-by-Step: Resetting the Engine Light with an OBD2 Scanner

Using an OBD2 scanner is the safest, most accurate way to reset the engine light on your 2014 Chevy Equinox. This method ensures that you’re not just clearing the light but also confirming that the underlying issue has been resolved.

Step 1: Locate the OBD2 Port

The OBD2 diagnostic port is typically located under the dashboard on the driver’s side. In the 2014 Chevy Equinox, it’s usually found near the steering column, just below the steering wheel. It’s a 16-pin connector that looks like a trapezoid-shaped plug. You may need to crouch down or use a flashlight to see it clearly.

Step 2: Turn Off the Ignition

Before plugging in the scanner, make sure the ignition is turned off. This prevents any electrical issues or damage to the scanner. Do not start the engine yet.

Step 3: Plug in the OBD2 Scanner

Insert the scanner’s plug into the OBD2 port. Make sure it’s securely connected. Most scanners will power on automatically when plugged in, even with the ignition off.

Step 4: Turn the Ignition to the “On” Position

Turn the key to the “On” position (but don’t start the engine). This powers up the vehicle’s electrical system and allows the scanner to communicate with the onboard computer. You’ll see dashboard lights illuminate, including the check engine light.

Step 5: Read the Trouble Codes

Follow the scanner’s instructions to read the stored trouble codes. Most scanners have a “Read Codes” or “Scan” button. Press it, and the device will display one or more codes (e.g., P0420, P0171). Write these down or take a photo for reference.

Step 6: Research the Codes

Use the scanner’s built-in code definitions or look up the codes online to understand what they mean. For example, P0171 indicates a “System Too Lean (Bank 1),” which could be caused by a vacuum leak or faulty mass airflow sensor. Knowing the issue helps you confirm whether it’s been fixed.

Step 7: Clear the Codes

Once you’re confident the problem has been resolved, use the scanner’s “Clear Codes” or “Reset” function. This will erase the stored trouble codes and turn off the check engine light. The scanner may ask for confirmation—select “Yes” or “OK.”

Step 8: Turn Off the Ignition and Unplug the Scanner

After clearing the codes, turn the ignition back to the “Off” position and unplug the scanner. The check engine light should now be off.

Step 9: Start the Engine

Start your vehicle and observe the dashboard. The check engine light should remain off. If it comes back on immediately, the problem may not be fully resolved, or a new issue has been detected.

Alternative Method: Disconnecting the Battery

If you don’t have an OBD2 scanner, you can reset the engine light by disconnecting the battery. This method forces the vehicle’s computer to reset, clearing stored codes and turning off the check engine light. However, it’s not as precise as using a scanner and comes with some drawbacks.

Step 1: Turn Off the Engine and Remove the Key

Make sure the engine is off and the key is removed from the ignition. This prevents any electrical surges or damage.

Step 2: Locate the Battery

In the 2014 Chevy Equinox, the battery is located in the engine compartment on the driver’s side. Open the hood and secure it with the prop rod.

Step 3: Disconnect the Negative Terminal

Use a 10mm wrench or socket to loosen the nut on the negative (-) battery terminal. The negative cable is usually black and marked with a minus sign. Carefully remove the cable from the terminal and tuck it aside so it doesn’t touch the battery post.

Step 4: Wait 15–30 Minutes

Leave the battery disconnected for at least 15 minutes. This allows the vehicle’s computer (ECU) to fully discharge and reset. Some sources recommend up to 30 minutes for a complete reset.

Step 5: Reconnect the Battery

Reattach the negative cable to the battery terminal and tighten the nut securely. Make sure the connection is tight to avoid electrical issues.

Step 6: Start the Engine

Turn the ignition to the “On” position and then start the engine. The check engine light should be off. However, you may notice that other systems—like the radio, clock, or power windows—need to be reset or relearned.

Drawbacks of Battery Disconnection

  • Erases saved settings: Radio presets, seat memory, and climate control settings may be lost.
  • Requires drive cycles: The vehicle may need to complete several drive cycles before the system rechecks and confirms repairs.
  • May not clear all codes: Some persistent or hard codes may not be cleared by a simple battery disconnect.

Using the Gas Cap Method (For Minor Issues)

In some cases, the check engine light comes on because of a loose or faulty gas cap. The 2014 Chevy Equinox has an evaporative emissions system that monitors fuel vapor leaks. If the gas cap isn’t tightened properly, the system detects a leak and triggers the light.

Step 1: Turn Off the Engine

Make sure the engine is off and the vehicle is parked on a level surface.

Step 2: Locate and Remove the Gas Cap

Open the fuel door and unscrew the gas cap. Inspect it for cracks, wear, or damage. A damaged cap should be replaced.

Step 3: Clean the Cap and Threads

Wipe the cap and the fuel filler neck with a clean cloth to remove dirt or debris. This ensures a proper seal.

Step 4: Reinstall the Gas Cap

Screw the cap back on tightly. You should hear it click several times as it seals. Over-tightening can damage the threads, so stop once it’s snug.

Step 5: Drive the Vehicle

Drive your Equinox for 50–100 miles. The vehicle’s computer will monitor the system and, if no leak is detected, turn off the check engine light automatically. This process can take a few days depending on driving habits.

Drive Cycles and System Rechecks

After resetting the engine light, your 2014 Chevy Equinox may need to complete one or more “drive cycles” for the onboard computer to recheck the systems and confirm that repairs were successful. A drive cycle is a specific pattern of driving conditions that allows the vehicle to test emissions and engine functions.

Typical Drive Cycle for Chevy Equinox

  • Start the engine and let it idle for 2–3 minutes (cold start).
  • Drive at 30–40 mph for 5 minutes.
  • Accelerate to 55–60 mph and maintain speed for 10 minutes.
  • Decelerate slowly without braking for 3 minutes.
  • Drive in stop-and-go traffic for 10 minutes.
  • Let the engine idle for 2 minutes before turning it off.

Completing this cycle helps the vehicle’s computer run all necessary tests. If the check engine light remains off after a few cycles, the issue is likely resolved. If it returns, further diagnosis is needed.

Troubleshooting Common Issues

Even after resetting the engine light, you might encounter problems. Here’s how to handle common scenarios.

Check Engine Light Comes Back On

If the light returns shortly after resetting, the original problem may not be fully fixed. Use an OBD2 scanner to read the new or recurring codes. Common causes include faulty oxygen sensors, catalytic converter issues, or ignition coil problems.

Scanner Won’t Connect

If your OBD2 scanner doesn’t power on or connect, check the following:

  • Ensure the ignition is in the “On” position.
  • Verify the OBD2 port is clean and undamaged.
  • Try a different scanner or test the current one on another vehicle.
  • Check the vehicle’s fuse box for a blown fuse related to the OBD system.

Battery Disconnect Didn’t Work

If disconnecting the battery didn’t reset the light, the issue may be more complex. Some codes require a scanner to clear, especially those related to emissions or transmission. Also, ensure you waited long enough (at least 15 minutes) for the ECU to reset.

Radio or Settings Reset After Battery Disconnect

This is normal. To restore radio presets, re-enter your favorite stations. Some models may require a security code—check your owner’s manual or contact a Chevy dealer.

When to See a Mechanic

While many check engine light issues can be resolved at home, some problems require professional attention. Consider visiting a certified mechanic if:

  • The check engine light is flashing (indicates a severe misfire that can damage the catalytic converter).
  • You’re unable to read or interpret trouble codes.
  • The light returns repeatedly after resetting.
  • You notice performance issues like rough idling, stalling, or reduced power.
