Step-by-Step Guide to Chevrolet Bolt EV TPMS Reset and Relearn

Step-by-Step Guide to Chevrolet Bolt EV TPMS Reset and Relearn

Learn how to reset and relearn TPMS in Chevrolet Bolt EV with this step-by-step guide. Covers all generations, troubleshooting tips, required tools, and maintenance best practices to ensure optimal safety, performance, and efficiency of your Bolt EV.

The Tire Pressure Monitoring System (TPMS) is a crucial safety feature in modern vehicles, including the Chevrolet Bolt EV. It helps drivers maintain optimal tire pressure, ensuring better fuel efficiency, handling, and tire longevity. However, there are times when you need to reset and relearn the TPMS, such as after rotating tires or installing new sensors. This comprehensive guide will walk you through the process for all generations of the Chevrolet Bolt EV.

Understanding TPMS in Chevrolet Bolt EV

Before diving into the reset and relearn process, it’s essential to understand what TPMS is and why it’s important:

• TPMS continuously monitors the air pressure in your tires
• It alerts you when one or more tires are significantly under-inflated
• Proper tire pressure improves safety, fuel economy, and tire life
• The Bolt EV uses direct TPMS, which means each wheel has its own sensor

When to Reset and Relearn TPMS

You’ll need to reset and relearn the TPMS in the following situations:

• After rotating your tires
• When replacing one or more TPMS sensors
• After switching between summer and winter tires
• If you’re experiencing persistent TPMS warnings despite proper inflation

Tools Required for TPMS Reset and Relearn

To successfully reset and relearn the TPMS on your Chevrolet Bolt EV, you’ll need:

• A TPMS relearn tool (e.g., EL-50448 or equivalent)
• A tire pressure gauge
• An air compressor (optional, but recommended)

The TPMS relearn tool is crucial for this process. You can purchase one for around $10-$15 on Amazon or other online retailers.

Step-by-Step Guide to Reset and Relearn TPMS

Now, let’s go through the detailed process of resetting and relearning the TPMS on your Chevrolet Bolt EV. This process is similar across all generations, with minor variations in the user interface.

Step 1: Prepare Your Vehicle

1. Ensure all tires are properly inflated to the recommended pressure
2. Park your Bolt EV in a safe location away from traffic
3. Turn off the engine and remove the key from the ignition

Step 2: Enter TPMS Relearn Mode

1. Without pressing the brake pedal, press and hold the Start/Stop button to put the vehicle in accessory mode
2. Using the steering wheel controls, navigate to the Vehicle Information menu
3. Scroll to the tire pressure screen
4. Press and hold the checkmark button until you hear two horn chirps (about 5 seconds)
5. The Driver Information Center should display “Tire Learning Active”

Step 3: Relearn TPMS Sensors

Now, you’ll use the TPMS relearn tool to activate each sensor in a specific order:

1. Start with the driver’s side front tire
2. Hold the TPMS relearn tool against the tire sidewall near the valve stem
3. Press the button on the tool to activate the sensor
4. Wait for a horn chirp, which confirms the sensor has been recognized
5. Move to the passenger’s side front tire and repeat the process
6. Continue to the passenger’s side rear tire
7. Finish with the driver’s side rear tire

Note: The Bolt EV will illuminate the turn signal on the side of the vehicle where you should be working, guiding you through the process.

Step 4: Complete the Relearn Process

After activating all four sensors:

1. Wait for two horn chirps, indicating the relearn process is complete
2. The Driver Information Center should exit the relearn mode automatically
3. Turn off the vehicle

Step 5: Verify TPMS Operation

1. Start the vehicle normally
2. Check the Driver Information Center for updated tire pressure readings
3. Ensure there are no TPMS warning lights or messages

Troubleshooting TPMS Reset and Relearn

If you encounter issues during the reset and relearn process, consider these troubleshooting steps:

TPMS Light Remains On

• Double-check tire pressures and adjust if necessary
• Repeat the relearn process, ensuring you hear the confirmation chirps
• Check for damaged or faulty TPMS sensors

No Horn Chirp During Relearn

• Ensure the TPMS relearn tool is functioning (check battery)
• Position the tool closer to the tire sidewall near the valve stem
• Try activating the sensor multiple times

Persistent “Service Tire Monitor System” Message

If you continue to see this message after completing the relearn process:

• Check for any damaged TPMS sensors
• Ensure all sensors are compatible with your Bolt EV model year
• Consider having the system diagnosed by a professional

TPMS Sensor Replacement

Sometimes, you may need to replace one or more TPMS sensors. Here’s what you need to know:

When to Replace TPMS Sensors

• Sensors are typically designed to last 5-10 years
• Replace if you’re experiencing frequent TPMS malfunctions
• Consider replacement when changing from winter to summer tires (if using separate wheel sets)

Choosing the Right TPMS Sensors

When replacing sensors:

• Ensure compatibility with your specific Bolt EV model year
• Consider OEM (Original Equipment Manufacturer) sensors for guaranteed fit
• Aftermarket sensors can be a cost-effective alternative but verify compatibility

Professional vs. DIY Replacement

While it’s possible to replace TPMS sensors yourself if you’re comfortable working on your vehicle, professional installation ensures:

• Proper sensor programming
• Correct installation to prevent air leaks
• Proper disposal of old sensors (which contain batteries)

Maintaining Your TPMS

To keep your TPMS functioning correctly and avoid unnecessary resets:

Regular Maintenance

• Check tire pressure monthly, including the spare tire
• Inspect TPMS sensors during tire rotations or changes
• Keep valve stems and caps clean and in good condition

Seasonal Considerations

• Tire pressure can fluctuate with temperature changes
• Recheck and adjust tire pressure as seasons change
• Perform TPMS relearn when switching between summer and winter tires

Understanding TPMS Warnings

The Chevrolet Bolt EV may display different TPMS-related warnings:

TPMS and Vehicle Safety

Understanding and maintaining your Chevrolet Bolt EV’s TPMS is crucial for several reasons:

Safety Benefits

• Reduces the risk of tire blowouts
• Improves vehicle handling and stability
• Enhances braking performance

Efficiency Improvements

• Properly inflated tires can increase range in electric vehicles
• Reduces tire wear, extending tire life
• Optimizes energy consumption

Conclusion

Resetting and relearning the TPMS on your Chevrolet Bolt EV is a straightforward process that can be done at home with the right tools and knowledge. By following this guide, you can ensure your TPMS is functioning correctly, providing accurate tire pressure information and contributing to the safety and efficiency of your vehicle.

Remember, while the TPMS is an excellent tool for monitoring tire pressure, it doesn’t replace regular manual checks. Make tire pressure checks a part of your routine maintenance to keep your Chevrolet Bolt EV running safely and efficiently.

By understanding and properly maintaining your TPMS, you’re not just following best practices – you’re actively contributing to your safety on the road and the longevity of your vehicle. Whether you’re a new Bolt EV owner or have been driving one for years, mastering the TPMS reset and relearn process is a valuable skill that will serve you well throughout your ownership experience.
