The Tire Pressure Monitoring System (TPMS) is a crucial safety feature in modern vehicles, including the Lexus RC. It alerts drivers when tire pressure is low, helping to prevent accidents and improve fuel efficiency. However, there are times when you need to reset or relearn the TPMS, such as after rotating tires or replacing sensors. This comprehensive guide will walk you through the process for all generations of the Lexus RC.

Understanding TPMS in Lexus RC Models

Before diving into the reset procedures, it’s essential to understand how TPMS works in Lexus RC vehicles:

• Direct TPMS: Lexus RC models use a direct TPMS, which means each wheel has a sensor that measures tire pressure and temperature.
• Wireless Communication: These sensors wirelessly transmit data to the vehicle’s TPMS module.
• Dashboard Warning: When tire pressure is low, a warning light illuminates on the dashboard.

When to Reset or Relearn TPMS

You should reset or relearn your Lexus RC’s TPMS in the following situations:

• After rotating tires
• When replacing one or more TPMS sensors
• After adjusting tire pressure
• When the TPMS light remains on even after properly inflating tires

General TPMS Reset Procedure for Lexus RC

While specific steps may vary slightly between generations, the general process for resetting TPMS in a Lexus RC is as follows:

1. Ensure all tires are inflated to the correct pressure as specified on the driver’s side door jamb placard.
2. Turn the ignition to the “ON” position without starting the engine.
3. Locate the TPMS reset button, usually found under the steering wheel or in the glove compartment.
4. Press and hold the TPMS reset button until the tire pressure warning light blinks three times.
5. Start the engine and wait for about 20 minutes to allow the system to recalibrate.

Now, let’s explore the specific procedures for each generation of the Lexus RC.

First Generation Lexus RC (2014-2020) TPMS Reset

The first generation Lexus RC, introduced in 2014, includes models such as the RC 300, RC 350, and RC F. Here’s how to reset the TPMS on these vehicles:

1. Inflate all tires to the pressure listed on the tire placard.
2. Turn the ignition to the “ON” position (engine off).
3. Locate the TPMS reset button on the instrument panel, typically near the steering column.
4. Press and hold the reset button until the TPMS warning light flashes three times.
5. Start the engine and wait for about 20 minutes.
6. Drive the vehicle for approximately 10-20 minutes at speeds above 25 mph to complete the relearn process.

Troubleshooting First Generation TPMS Reset

If the reset process doesn’t work, try these steps:

• Double-check tire pressures and adjust if necessary.
• Ensure the TPMS sensors are functioning correctly. You may need a TPMS diagnostic tool to verify this.
• If problems persist, consult a Lexus dealership or certified mechanic.

Second Generation Lexus RC (2021-Present) TPMS Reset

The second generation Lexus RC, introduced in 2021, features an updated TPMS system. Here’s how to reset it:

1. Adjust tire pressures to the recommended values.
2. Turn the ignition to the “ON” position.
3. Navigate to the vehicle settings menu on the multi-information display using the steering wheel controls.
4. Select “TPMS” from the menu.
5. Press and hold the “OK” button until the TPMS warning light blinks three times.
6. Start the engine and drive for about 10-20 minutes at speeds above 25 mph to complete the relearn process.

Using the Multimedia Display for TPMS Reset

Some newer Lexus RC models allow TPMS reset through the multimedia display:

1. Tap the gear icon on the left tab menu of the multimedia display.
2. Select “Vehicle Customize”.
3. Choose the “Tire Pressure” menu.
4. Tap “Set Current Air Pressure”.
5. When prompted, select “Continue” to complete the reset.

TPMS Sensor Replacement and Relearn

If you need to replace TPMS sensors in your Lexus RC, the process is more complex and may require special tools:

Tools Required

• TPMS programming tool (e.g., Autel MaxiTPMS TS508)
• New TPMS sensors compatible with your Lexus RC model
• Torque wrench
• Valve core tool

TPMS Sensor Replacement Process

1. Remove the tire from the wheel following proper safety procedures.
2. Remove the old TPMS sensor from the wheel.
3. Install the new TPMS sensor, ensuring it’s properly seated and the valve stem is correctly positioned.
4. Reinstall the tire on the wheel and inflate to the correct pressure.

TPMS Sensor Relearn Process

After replacing sensors, you’ll need to relearn them to the vehicle:

1. Turn on the TPMS programming tool and select your Lexus RC model and year.
2. Choose “ID Programming” or a similar option.
3. Follow the tool’s instructions to program each new sensor.
4. Once all sensors are programmed, perform the TPMS reset procedure as described earlier for your specific RC generation.

Tips for Maintaining Your Lexus RC’s TPMS

To ensure your TPMS functions correctly and avoid unnecessary resets:

• Check tire pressure monthly, including the spare tire.
• Rotate tires according to the maintenance schedule in your owner’s manual.
• Have TPMS sensors checked during routine maintenance.
• Replace TPMS sensor batteries when recommended (usually every 5-7 years).
• Be cautious when using tire sealants, as they can damage TPMS sensors.

Troubleshooting Common TPMS Issues in Lexus RC

If you’re experiencing persistent TPMS problems, consider these potential issues:

TPMS Light Stays On After Reset

• Double-check tire pressures, including the spare.
• Ensure all TPMS sensors are functioning correctly.
• Check for damaged wheels or tires that may interfere with sensor signals.

Intermittent TPMS Warnings

• Temperature changes can affect tire pressure. Check pressures when tires are cold.
• Look for slow leaks in tires or valve stems.
• Ensure wheel weights haven’t damaged TPMS sensors.

No Pressure Readings Displayed

• Verify that your Lexus RC model displays individual tire pressures (some older models may not).
• Check for interference from other electronic devices.
• Consult a Lexus dealership to diagnose potential TPMS module issues.

The Importance of Proper TPMS Function

Maintaining a properly functioning TPMS in your Lexus RC is crucial for several reasons:

• Safety: Properly inflated tires reduce the risk of blowouts and improve handling.
• Fuel Efficiency: Correct tire pressure can improve fuel economy by up to 3%.
• Tire Longevity: Properly inflated tires wear more evenly, extending their lifespan.
• Legal Compliance: Many jurisdictions require functional TPMS for vehicle inspections.

Conclusion

Resetting and relearning the TPMS in your Lexus RC is a straightforward process that can be done at home in most cases. By following the steps outlined in this guide, you can ensure your vehicle’s TPMS functions correctly, providing you with accurate tire pressure information and enhancing your safety on the road.

Remember, while TPMS is a valuable tool, it doesn’t replace regular tire maintenance. Always visually inspect your tires and check pressures manually as part of your routine vehicle care. If you encounter persistent TPMS issues or are uncomfortable performing these procedures yourself, don’t hesitate to consult a Lexus dealership or certified mechanic.

By keeping your Lexus RC’s TPMS in top condition, you’re not just maintaining a system – you’re investing in your safety, your vehicle’s performance, and your peace of mind on every journey.
