This guide will walk you through the process for all generations of the Toyota Harrier.<>
Understanding TPMS in Toyota Harrier
Before diving into the reset and relearn procedures, it’s essential to understand what TPMS is and how it functions in the Toyota Harrier.<>
What is TPMS?
TPMS, or Tire Pressure Monitoring System, 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 Harrier
Toyota Harrier models may use one of two types of TPMS:<>
- Direct TPMS: Uses sensors inside each tire to measure pressure directly.
- Indirect TPMS: Uses the ABS system to detect differences in wheel rotation speeds, which can indicate low tire pressure.
Most modern Toyota Harrier models use direct TPMS for more accurate pressure readings.<>
When to Reset or Relearn TPMS
You should reset or relearn your Toyota Harrier’s TPMS in the following situations:<>
- After rotating tires
- When replacing one or more tires
- After changing TPMS sensors
- When the TPMS warning light remains on after inflating tires to the correct pressure
- When swapping between summer and winter tire sets
TPMS Reset and Relearn Procedures for Toyota Harrier Generations
The process for resetting and relearning the TPMS can vary slightly between different generations of the Toyota Harrier. We’ll cover the procedures for each generation, starting with the most recent.<>
Third Generation Toyota Harrier (2013-Present)
For the latest generation of Toyota Harrier, follow these steps:<>
- Ensure all tires are inflated to the correct pressure as specified in your owner’s manual or on the driver’s side door jamb sticker.
- Turn the ignition to the “ON” position without starting the engine.
- Locate the TPMS reset button. It’s usually found under the steering wheel or in the glove box.
- Press and hold the TPMS reset button until the tire pressure warning light blinks three times.
- Release the button and start the engine.
- Drive the vehicle at speeds above 25 mph (40 km/h) for about 10-20 minutes to allow the system to relearn the new tire pressures.
If the TPMS light doesn’t turn off after this procedure, you may need to use an OBD-II scan tool to perform a full relearn process.<>
Second Generation Toyota Harrier (2003-2013)
The process for the second generation is similar to the third, with a few minor differences:<>
- Inflate all tires to the correct pressure.
- Turn the ignition to “ON” without starting the engine.
- Locate the TPMS reset button, typically under the dashboard on the driver’s side.
- Press and hold the reset button until the TPMS light flashes three times.
- Release the button and start the engine.
- Drive the vehicle for about 10 minutes at speeds over 25 mph to complete the relearn process.
First Generation Toyota Harrier (1997-2003)
The first generation Toyota Harrier may not have a TPMS system, as it predates the mandatory TPMS requirement in many countries. If your first-generation Harrier does have TPMS, it’s likely an indirect system that uses the ABS to detect low tire pressure. For these models:<>
- Ensure all tires are properly inflated.
- Locate the TPMS reset button, which may be near the parking brake or under the dashboard.
- Turn the ignition to “ON” without starting the engine.
- Press and hold the reset button until the TPMS light flashes.
- Start the engine and drive for about 10 minutes to calibrate the system.
Using an OBD-II TPMS Tool for Complex Relearn Procedures
In some cases, especially after replacing TPMS sensors or when the simple reset procedure doesn’t work, you may need to use an OBD-II TPMS tool. Here’s how to use it:<>
- Connect the OBD-II TPMS tool to your Toyota Harrier’s OBD-II port, usually located under the dashboard on the driver’s side.
- Turn on the ignition without starting the engine.
- Follow the tool’s instructions to initiate the TPMS relearn procedure.
- The tool will communicate with each TPMS sensor and register their IDs with the vehicle’s ECU.
- Once all sensors are registered, the tool will finalize the process and clear any TPMS-related error codes.
Using an OBD-II TPMS tool can be particularly helpful when dealing with stubborn TPMS issues or when performing a complete sensor replacement.<>
Troubleshooting Common TPMS Issues in Toyota Harrier
Even after performing a reset or relearn procedure, you might encounter some TPMS-related issues. Here are some common problems and their potential solutions:<>
TPMS Light Stays On
If the TPMS light remains illuminated after resetting:<>
- Double-check tire pressures and adjust if necessary
- Ensure all TPMS sensors are functioning properly
- Perform the relearn procedure again
- Consider using an OBD-II TPMS tool for a full system reset
Intermittent TPMS Light
An intermittently illuminating TPMS light could indicate:<>
- A slow leak in one or more tires
- Temperature-related pressure changes
- A failing TPMS sensor battery
TPMS Sensor Battery Replacement
TPMS sensor batteries typically last 5-10 years. If your Toyota Harrier is older, consider replacing the TPMS sensors to ensure reliable operation.<>
Maintaining Your Toyota Harrier’s TPMS
To keep your TPMS functioning correctly and avoid unnecessary warnings:<>
- Check tire pressures regularly, at least once a month
- Adjust tire pressures when there are significant temperature changes
- Have your TPMS sensors checked during routine maintenance
- Replace TPMS sensors when their batteries are nearing the end of their lifespan
- Always use TPMS-compatible tires and wheels when replacing them
The Importance of Proper Tire Pressure
Maintaining correct tire pressure in your Toyota Harrier is crucial for several reasons:<>
- Improved fuel efficiency
- Extended tire life
- Better handling and stability
- Reduced risk of tire failure
- Enhanced overall vehicle safety
The TPMS in your Toyota Harrier helps ensure these benefits by alerting you to potential pressure issues before they become serious problems.<>
TPMS and Tire Rotation
When rotating tires on your Toyota Harrier, it’s important to consider the TPMS:<>
- Note the position of each TPMS sensor before rotation
- After rotation, perform the TPMS reset and relearn procedure
- If your Harrier has different front and rear tire pressures, adjust accordingly after rotation
- Allow the system to relearn the new sensor positions by driving for 10-20 minutes
TPMS and Seasonal Tire Changes
If you switch between summer and winter tires on your Toyota Harrier:<>
- Consider having a second set of TPMS sensors for your alternate wheels
- Perform a TPMS reset and relearn procedure after each seasonal change
- Ensure the correct tire pressures for the season are set
- Store unused tires with sensors properly to preserve battery life
Advanced TPMS Features in Newer Toyota Harrier Models
Recent Toyota Harrier models may include advanced TPMS features:<>
- Individual tire pressure displays on the instrument cluster or infotainment screen
- Temperature compensation for more accurate pressure readings
- Integration with the vehicle’s navigation system for location-based pressure adjustments
- Automatic TPMS relearn capabilities in some models
Check your owner’s manual for specific advanced features in your Toyota Harrier model.<>
Legal Requirements and TPMS
It’s important to note that TPMS is not just a convenience feature but a legal requirement in many countries:<>
- In the United States, TPMS has been mandatory on all new vehicles since 2007
- The European Union mandated TPMS on all new passenger vehicles from 2014
- Japan introduced TPMS requirements for new vehicles in 2018
Keeping your Toyota Harrier’s TPMS in good working order is not only beneficial for safety and performance but may also be a legal obligation depending on your location.<>
When to Seek Professional Help
