Resetting the Tire Pressure Sensor on the 2021 Harley Davidson Road Glide
The tire pressure monitoring system (TPMS) is a crucial feature in the 2021 Harley-Davidson Road Glide, alerting riders when tire pressure falls below the recommended levels. However, sometimes the TPMS light may flash or remain illuminated even after correcting the tire pressure. This can indicate that the tire pressure sensors need to be reset. Here’s how to do it effectively.
Steps to Reset the Tire Pressure Sensor
- Ensure that all tires are inflated to the recommended pressure as specified in the owner’s manual.
- Turn the ignition switch to the “ON” position without starting the engine.
- Locate the TPMS reset button, usually found beneath the steering column or on the dashboard.
- Press and hold the TPMS reset button until you see the TPMS light blink three times, then release the button.
- Start the engine and allow the motorcycle to run for a few minutes. This will help the system recalibrate.
- Check if the TPMS light is off. If it remains on, repeat the process.
Tire Pressure Monitoring System Light Flashing
If the TPMS light is flashing, it indicates a malfunction in the system. This could be due to a few reasons, including a dead battery in one of the tire sensors or a fault in the TPMS itself. Here’s what you should check:
Common Causes for Flashing TPMS Light
| Issue | Description | Solution |
|---|---|---|
| Low Tire Pressure | One or more tires are below the recommended pressure. | Inflate tires to the correct pressure. |
| Faulty Sensor | A tire pressure sensor may be malfunctioning or dead. | Replace the faulty sensor. |
| System Error | The TPMS may have a software issue. | Reset the TPMS or consult a technician. |
Regular Maintenance and Checks
Maintaining proper tire pressure and ensuring the TPMS functions correctly is vital for safety. Here are some maintenance tips:
- Check tire pressure at least once a month.
- Inspect tire sensors for damage during routine maintenance.
- Replace batteries in tire sensors as needed.
- Keep an eye on the TPMS light and address issues promptly.
Importance of Maintaining Proper Tire Pressure
Proper tire pressure is crucial for the performance, safety, and longevity of your 2021 Harley-Davidson Road Glide. Riding with incorrect tire pressure can lead to several issues, including decreased fuel efficiency, poor handling, and increased tire wear. Maintaining the recommended tire pressure ensures optimal contact with the road, enhancing stability and traction.
Effects of Incorrect Tire Pressure
Riding with either under-inflated or over-inflated tires can have significant consequences:
- Under-Inflation: Leads to increased rolling resistance, poor fuel economy, and overheating, which can cause tire blowouts.
- Over-Inflation: Results in reduced contact patch, making the bike more susceptible to skidding and decreased ride comfort.
Maintaining the correct tire pressure not only enhances safety but also contributes to a better overall riding experience.
How to Check Tire Pressure
Regularly checking tire pressure is essential for safe riding. Here’s how to do it effectively:
- Gather Necessary Tools: You will need a reliable tire pressure gauge and an air compressor.
- Check When Tires Are Cold: Measure tire pressure in the morning or after the bike has been parked for a few hours to ensure accurate readings.
- Remove Valve Stem Cap: Unscrew the cap from the valve stem on the tire you wish to check.
- Press Gauge onto Valve: Firmly press the tire pressure gauge onto the valve stem to get a reading.
- Note the Reading: Compare the reading with the recommended tire pressure listed in the owner’s manual.
- Adjust Pressure if Necessary: If the pressure is too low, add air until it reaches the recommended level. If it’s too high, release some air.
- Replace Valve Stem Cap: Always put the valve stem cap back on to prevent dirt and moisture from entering.
Useful Tips for Tire Maintenance
To ensure the longevity and performance of your tires, consider the following tips:
- Inspect Tires Regularly: Look for signs of wear, cracks, or foreign objects lodged in the tread.
- Rotate Tires: Regularly rotate your tires as recommended by the manufacturer to promote even wear.
- Align Wheels: Ensure your wheels are properly aligned to prevent uneven tire wear.
- Monitor Weather Conditions: Temperature changes can affect tire pressure; check more frequently during extreme weather.
- Keep a Tire Pressure Gauge Handy: Regularly checking tire pressure should become part of your routine maintenance.
By following these guidelines, you can maintain optimal tire pressure, ensuring a safer and more enjoyable ride on your Harley-Davidson Road Glide.
