How to Reset and Relearn the TPMS of Toyota Alphard in All Generations

How to Reset and Relearn the TPMS of Toyota Alphard in All Generations

The Toyota Alphard is a luxury minivan known for its comfort and advanced features, including the Tire Pressure Monitoring System (TPMS). This system is crucial for maintaining optimal tire pressure, ensuring safety, and improving fuel efficiency. In this comprehensive guide, we’ll walk you through the process of resetting and relearning the TPMS for all generations of the Toyota Alphard.

Understanding TPMS in Toyota Alphard

Before we dive into the reset and relearn procedures, it’s essential to understand what TPMS is and how it functions in the Toyota Alphard.

What is TPMS?

TPMS is a safety feature that monitors the air pressure in your vehicle’s tires. It alerts the driver when one or more tires are significantly under-inflated, potentially creating unsafe driving conditions.

Types of TPMS in Toyota Alphard

Toyota Alphard models use two types of TPMS:

1. Direct TPMS: Uses sensors in each wheel to measure tire pressure directly.
2. Indirect TPMS: Uses wheel speed sensors from the ABS system to detect under-inflated tires based on rotational differences.

Knowing which type your Alphard uses is crucial for proper reset and relearn procedures.

When to Reset and Relearn TPMS

You should reset and relearn your Toyota Alphard’s TPMS in the following situations:

• After rotating tires
• When replacing one or more tires
• After changing a TPMS sensor
• When the TPMS warning light remains on after properly inflating all tires

General Steps for TPMS Reset and Relearn

While the specific procedure may vary slightly between generations, here’s a general overview of the process:

1. Ensure all tires, including the spare, are properly inflated to the recommended pressure.
2. Turn the ignition to the “ON” position without starting the engine.
3. Locate the TPMS reset button (usually under the steering wheel or in the glove box).
4. Press and hold the reset button until the TPMS light blinks three times.
5. Start the engine and wait for about 20 minutes to allow the system to relearn the new tire pressures.

Now, let’s look at the specific procedures for each generation of the Toyota Alphard.

First Generation Toyota Alphard (2002-2008)

The first-generation Alphard used an indirect TPMS system.

Reset Procedure:

1. Inflate all tires to the correct pressure.
2. Turn the ignition to “ON” without starting the engine.
3. Press and hold the TPMS reset button (located under the dashboard on the driver’s side) for about 3 seconds.
4. The TPMS warning light will flash three times to indicate a successful reset.
5. Start the engine and drive for at least 10 minutes at speeds above 20 mph to complete the relearn process.

Second Generation Toyota Alphard (2008-2015)

The second-generation Alphard introduced a direct TPMS system.

Reset and Relearn Procedure:

1. Ensure all tires are properly inflated.
2. Turn the ignition to “ON” without starting the engine.
3. Press and hold the TPMS reset button until the TPMS light blinks three times (about 3 seconds).
4. Start the engine and drive the vehicle for at least 10 minutes at speeds above 20 mph.
5. The system will automatically relearn the new tire pressures and sensor locations.

Third Generation Toyota Alphard (2015-Present)

The current generation Alphard uses an advanced direct TPMS system with individual tire pressure displays.

Reset and Relearn Procedure:

1. Inflate all tires to the correct pressure.
2. Turn the ignition to “ON” without starting the engine.
3. Using the multi-information display controls on the steering wheel, navigate to the “Vehicle Settings” menu.
4. Select “TPMS” and then “Set Pressure”.
5. Press and hold the “OK” button until the TPMS light blinks three times.
6. Start the engine and drive for at least 10 minutes at speeds above 20 mph to complete the relearn process.

Troubleshooting TPMS Issues

If you encounter problems during the reset or relearn process, consider the following:

• Ensure all tires are properly inflated, including the spare.
• Check for damaged or corroded TPMS sensors.
• Verify that all TPMS sensors are correctly installed and functioning.
• Consider using a TPMS diagnostic tool to identify specific sensor issues.

If problems persist, it’s advisable to consult a Toyota dealership or a certified mechanic familiar with the Alphard’s TPMS.

Importance of Proper TPMS Maintenance

Maintaining a properly functioning TPMS in your Toyota Alphard is crucial for several reasons:

• Safety: Properly inflated tires reduce the risk of blowouts and improve vehicle 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.
• Environmental Impact: Optimal tire pressure reduces rolling resistance, lowering CO2 emissions.

Best Practices for TPMS Maintenance

To ensure your Toyota Alphard’s TPMS functions optimally:

1. Check tire pressure monthly, including the spare.
2. Use a high-quality tire pressure gauge for accurate readings.
3. Rotate tires according to the manufacturer’s recommendations.
4. Replace TPMS sensors when replacing tires, or at least every 5-7 years.
5. Have the TPMS inspected during regular vehicle maintenance.

TPMS and Tire Rotation

When rotating tires on your Toyota Alphard, it’s important to consider the TPMS:

• For vehicles with direct TPMS, the system may need to be reset and relearned after rotation.
• Some Alphard models may have different front and rear tire pressures, requiring adjustment after rotation.
• Always refer to the tire placard (usually located on the driver’s side door jamb) for correct pressures.

TPMS and Seasonal Tire Changes

If you switch between summer and winter tires on your Alphard:

• Consider purchasing a second set of TPMS sensors for your seasonal wheels.
• Always reset and relearn the TPMS after changing to seasonal tires.
• Adjust tire pressures according to temperature changes, as pressure decreases in cold weather.

Advanced TPMS Features in Newer Alphard Models

Recent Toyota Alphard models come with advanced TPMS features:

• Individual tire pressure display on the multi-information screen
• Temperature compensation for more accurate readings
• Auto-location feature that identifies the position of each tire

These features enhance the system’s accuracy and user-friendliness but may require more complex reset and relearn procedures.

TPMS and Vehicle Customization

If you’ve modified your Toyota Alphard with non-standard wheels or tires:

• Ensure the new wheels are compatible with the existing TPMS sensors.
• Consider reprogramming the TPMS if tire sizes have changed significantly.
• Be aware that extreme modifications may affect TPMS functionality and require professional recalibration.

Legal Considerations

It’s important to note that TPMS is a legally required safety feature in many countries:

• In the United States, all vehicles manufactured after 2007 must have TPMS.
• Many European countries have similar requirements.
• Disabling or tampering with the TPMS may be illegal and could affect your vehicle’s roadworthiness.

Always ensure your Alphard’s TPMS is functioning correctly to comply with local regulations.

Future of TPMS Technology

As automotive technology advances, TPMS systems are evolving:

• Integration with vehicle telematics for remote monitoring
• Predictive maintenance alerts based on tire wear patterns
• Enhanced accuracy through advanced sensor technology

Future Toyota Alphard models may incorporate these advancements, potentially changing reset and relearn procedures.
