The Tire Pressure Monitoring System (TPMS) is a crucial safety feature in modern vehicles, including the luxurious Lexus LC. This system alerts drivers when tire pressure is low, helping to prevent accidents and improve fuel efficiency. However, there are times when you may need to reset or relearn the TPMS, such as after tire rotations, replacements, or sensor changes. In this comprehensive guide, we’ll walk you through the process of resetting and relearning the TPMS for all generations of the Lexus LC.

Understanding TPMS in Lexus LC Models

Before we dive into the reset and relearn procedures, it’s essential to understand how TPMS works in Lexus LC vehicles:

  • Lexus uses a direct TPMS, which means each wheel has a sensor that measures tire pressure and temperature.
  • These sensors transmit data to the vehicle’s computer system, which then displays the information on the dashboard.
  • When tire pressure drops below a certain threshold, the TPMS warning light illuminates on the instrument panel.

When to Reset or Relearn TPMS

You may need to reset or relearn your Lexus LC’s TPMS in the following situations:

  • After rotating tires
  • When replacing one or more tires
  • After installing new TPMS sensors
  • If the TPMS light remains on after properly inflating all tires
  • When switching between summer and winter tire sets

TPMS Reset vs. Relearn: What’s the Difference?

It’s important to distinguish between resetting and relearning the TPMS:

  • Reset: This is a simple procedure that recalibrates the system after adjusting tire pressures or rotating tires. It doesn’t involve reprogramming sensor IDs.
  • Relearn: This more complex process is necessary when replacing sensors or switching to a different set of wheels. It involves programming new sensor IDs into the vehicle’s computer.

TPMS Reset Procedure for Lexus LC (All Generations)

The reset procedure for the Lexus LC is relatively straightforward and can be performed without special tools. Follow these steps:

  1. Ensure all tires are inflated to the correct pressure as indicated on the tire placard, usually located in the driver’s side door jamb.
  2. Turn the vehicle’s ignition to the “ON” position without starting the engine.
  3. Locate the TPMS reset button. In the Lexus LC, this is typically found in the vehicle settings menu on the multi-information display.
  4. Navigate to the vehicle settings menu using the steering wheel controls.
  5. Select “TPMS” or “Tire Pressure” from the menu options.
  6. Choose “Reset TPMS” or a similar option.
  7. Press and hold the reset button until the TPMS light blinks three times.
  8. Start the engine and wait for a few minutes. The TPMS light should turn off.
  9. Drive the vehicle at speeds above 25 mph for at least 10-20 minutes to complete the reset process.

Troubleshooting TPMS Reset

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

  • Double-check that all tires are properly inflated
  • Ensure you’re following the correct procedure for your specific Lexus LC model year
  • If the problem persists, there may be a faulty sensor or system malfunction requiring professional diagnosis

TPMS Relearn Procedure for Lexus LC

The relearn procedure is more complex and may require special tools. Here’s a general overview of the process:

  1. Obtain a TPMS relearn tool compatible with Lexus vehicles, such as the Autel MaxiTPMS TS508.
  2. Ensure the vehicle is in “accessory” mode (ignition on, engine off).
  3. Use the TPMS tool to read the ID codes of all four TPMS sensors.
  4. Access the vehicle’s TPMS relearn mode through the multi-information display.
  5. Use the TPMS tool to transfer the new sensor IDs to the vehicle’s computer.
  6. Wait for confirmation that the relearn process is complete.
  7. Start the engine and drive the vehicle to ensure the TPMS is functioning correctly.

Professional TPMS Relearn Services

If you’re not comfortable performing the relearn procedure yourself, consider these options:

  • Visit an authorized Lexus dealership for professional TPMS service
  • Seek out a reputable tire shop with experience in Lexus TPMS systems
  • Some auto parts stores offer TPMS relearn services for a fee

TPMS Maintenance Tips for Lexus LC Owners

To keep your TPMS functioning properly and avoid unnecessary resets or relearns, follow these maintenance tips:

  • Check tire pressure monthly, including the spare tire
  • Inspect TPMS sensors during tire rotations or changes for signs of damage or corrosion
  • Replace TPMS sensor batteries when they become weak (typically every 5-7 years)
  • Be cautious when using tire sealants, as they can damage TPMS sensors
  • Have your TPMS professionally inspected during regular vehicle maintenance

Understanding TPMS Warnings in Lexus LC Models

Lexus LC vehicles may display different TPMS warnings. Here’s what they mean:

WarningMeaningAction Required
Solid TPMS lightLow tire pressure detectedCheck and adjust tire pressures, then reset TPMS
Blinking TPMS lightTPMS malfunctionHave the system diagnosed by a professional
TPMS light with “CHECK SYSTEM” messageSensor battery low or communication errorMay require sensor replacement or professional diagnosis

The Importance of Proper TPMS Function in Lexus LC

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

  • Safety: Properly inflated tires reduce the risk of blowouts and improve vehicle handling.
  • Fuel Efficiency: Correct tire pressure helps optimize fuel consumption.
  • Tire Longevity: Maintaining proper tire pressure extends the life of your tires.
  • Performance: The Lexus LC’s high-performance capabilities rely on optimal tire conditions.

Future of TPMS Technology in Lexus Vehicles

As automotive technology advances, TPMS systems are evolving. Future Lexus LC models may incorporate:

  • Integration with advanced driver assistance systems (ADAS)
  • Predictive tire maintenance alerts based on driving patterns and conditions
  • Wireless sensor charging to eliminate battery replacement needs
  • Enhanced smartphone integration for real-time tire pressure monitoring

Conclusion

Resetting and relearning the TPMS in your Lexus LC is an essential skill for maintaining your vehicle’s safety and performance. While the reset procedure is relatively simple and can be performed by most owners, the relearn process may require special tools or professional assistance. By understanding these procedures and following proper maintenance practices, you can ensure your Lexus LC’s TPMS functions correctly, providing you with peace of mind on every journey.

Remember, if you’re ever unsure about performing TPMS procedures, it’s always best to consult your vehicle’s manual or seek assistance from an authorized Lexus service center. Proper tire maintenance and a functioning TPMS not only keep you safe but also contribute to the exceptional driving experience that Lexus LC owners have come to expect from their luxury vehicles.
