Why the Check Engine Light Comes On
Before jumping into resetting the light, it’s important to understand why it turned on in the first place. The check engine light—also known as the malfunction indicator lamp (MIL)—is part of your vehicle’s onboard diagnostics system (OBD2). When the car’s computer detects a problem with the engine, emissions system, or related components, it triggers the light to alert you.
In a 2013 Chevy Cruze, common causes include:
- Loose or faulty gas cap: A simple fix, but often overlooked. If the cap isn’t tightened properly, fuel vapors can escape, triggering the light.
- Oxygen sensor failure: These sensors monitor exhaust gases and help regulate fuel mixture. A faulty sensor can reduce fuel efficiency and increase emissions.
- Catalytic converter issues: Over time, the converter can become clogged or damaged, leading to poor performance and emissions problems.
- Mass airflow (MAF) sensor problems: This sensor measures how much air enters the engine. Dirt or malfunction can cause rough idling or stalling.
- Spark plug or ignition coil failure: Worn spark plugs or faulty coils can cause misfires, reducing power and fuel economy.
- Evaporative emissions system leaks: Small leaks in the EVAP system can trigger the light even if they don’t affect performance.
The key takeaway? Never reset the check engine light without first identifying and addressing the root cause. Resetting it while a problem persists is like turning off a fire alarm while the house is still burning—it doesn’t solve the issue.
Method 1: Using an OBD2 Scanner (Recommended)
The most accurate and reliable way to reset the check engine light in your 2013 Chevy Cruze is by using an OBD2 (On-Board Diagnostics) scanner. This tool plugs into your car’s diagnostic port and communicates directly with the engine control unit (ECU) to read error codes and clear the light.

Step 4: Turn the Ignition to “On” (But Don’t Start the Engine)
Turn the key to the “ON” position. This powers up the car’s electrical system and allows the scanner to communicate with the ECU. Do not start the engine at this point.
Step 5: Power On the Scanner
Press the power button on your OBD2 scanner. Wait a few seconds for it to initialize and establish a connection with the vehicle.
Step 6: Read the Trouble Codes
Use the scanner’s menu to select “Read Codes” or a similar option. The device will display one or more diagnostic trouble codes (DTCs), such as P0420 (catalytic converter efficiency) or P0171 (system too lean).
Step 7: Address the Underlying Issue
Before clearing the codes, make sure you’ve fixed the problem. For example, if the code indicates a loose gas cap, tighten it or replace it. If it’s a sensor issue, consider replacing the part or consulting a mechanic.
Step 8: Clear the Codes
Once the issue is resolved, go back to the scanner menu and select “Clear Codes” or “Erase Codes.” Confirm the action when prompted. The scanner will send a command to the ECU to reset the check engine light.
Step 9: Turn Off the Ignition and Unplug the Scanner
After clearing the codes, turn the ignition back to “OFF” and unplug the scanner. Wait about 30 seconds before starting the car.
Step 10: Start the Engine
Turn the key to start the engine. The check engine light should be off. If it remains on, the problem may not be fully resolved, or a new issue has arisen.
Tips for Using an OBD2 Scanner
- Choose a scanner with a clear display and easy-to-navigate menus. Bluetooth models that connect to your smartphone via an app are also popular.
- Keep the scanner’s software updated for the best compatibility with your vehicle.

Method 2: Disconnecting the Battery (Manual Reset)
If you don’t have an OBD2 scanner, you can reset the check engine light by disconnecting the car’s battery. This method forces the ECU to reset by cutting power to the system. However, it’s not as precise as using a scanner and comes with some drawbacks.
What You’ll Need
- Wrench or socket set (usually 10mm)
- Safety gloves and glasses
- Your 2013 Chevy Cruze
Step-by-Step Instructions
Step 1: Park the Car and Turn Off the Engine
Make sure the car is parked on a flat surface, the parking brake is engaged, and the engine is completely off.
Step 2: Locate the Battery
In the 2013 Chevy Cruze, 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 wrench to loosen the nut on the negative (black) battery terminal. Carefully remove the cable and tuck it away from the battery to prevent accidental contact. Always disconnect the negative terminal first to avoid short circuits.
Step 4: Wait 15–30 Minutes
Leave the battery disconnected for at least 15 minutes. This allows the ECU’s capacitors to fully discharge, ensuring a complete reset. For best results, wait 30 minutes.
Step 5: Reconnect the Battery
Reattach the negative terminal and tighten the nut securely. Make sure the connection is firm to avoid electrical issues.
Step 6: Start the Engine
Turn the key to start the car. The check engine light should be off. If it remains on, the issue may still be present.
Important Considerations
- Radio and settings reset: Disconnecting the battery may reset your radio presets, clock, and seat/mirror memory. You may need to re-enter security codes for the radio.
- Drive cycle required: After reconnecting the battery, you’ll need to complete a drive cycle to allow the ECU to relearn driving patterns and recheck systems. This typically involves a mix of city and highway driving over 30–50 miles.
- Not always effective: If the problem hasn’t been fixed, the light will likely return after the drive cycle.
Method 3: Drive Cycle Reset (Natural Reset)
In some cases, the check engine light will turn off on its own after the issue is resolved and the vehicle completes a series of drive cycles. This is known as a “natural reset” and relies on the ECU’s self-diagnostic system.
What Is a Drive Cycle?
A drive cycle is a specific sequence of driving conditions that allows the vehicle’s onboard computer to test various emissions and engine systems. For the 2013 Chevy Cruze, a typical drive cycle includes:
- Cold start (engine off for at least 8 hours)
- Idle for 2–3 minutes
- Drive at varying speeds (20–60 mph) for 10–15 minutes
- Include periods of acceleration, deceleration, and steady cruising
- Return home and turn off the engine
How Long Does It Take?
Depending on driving habits, it may take 3–7 days of regular driving for the ECU to complete all tests and turn off the light. However, if the problem persists, the light will remain on or return.
When to Use This Method
This method works best for minor issues like a loose gas cap that you’ve already fixed. It’s not reliable for serious mechanical problems.
Troubleshooting Common Issues
Even after resetting the check engine light, you may encounter problems. Here’s how to handle the most common scenarios:
Check Engine Light Comes Back On
If the light returns shortly after resetting, the original issue hasn’t been resolved. Use an OBD2 scanner to read the new codes and address the problem. Common culprits include failing oxygen sensors, catalytic converter issues, or persistent EVAP leaks.
Radio or Clock Resets After Battery Disconnect
This is normal. Re-enter your radio presets and set the clock. If your radio has a security code, refer to your owner’s manual or contact a Chevy dealer for assistance.
Car Runs Rough After Reset
If the engine idles roughly or hesitates after a reset, the ECU may still be relearning. Complete a full drive cycle and avoid aggressive driving for the first few days. If problems persist, have a mechanic inspect the vehicle.
OBD2 Scanner Won’t Connect
Ensure the ignition is in the “ON” position and the scanner is properly plugged in. Try a different scanner or check for blown fuses related to the OBD2 system.
