Properly maintaining your Coaster’s TPMS is crucial for ensuring safe and efficient operation of the vehicle. In this comprehensive guide, we’ll walk you through the steps to reset and relearn the TPMS on a Toyota Coaster across all generations.<>

What is TPMS and Why is it Important?

TPMS stands for Tire Pressure Monitoring System. It is an electronic system designed to monitor the air pressure inside the tires on your vehicle. When tire pressure drops below a certain level, the TPMS will alert the driver by illuminating a warning light on the dashboard.<>

Proper tire inflation is critical for several reasons:<>

  • Ensures optimal vehicle handling and braking
  • Promotes even tread wear and extends tire life
  • Improves fuel efficiency
  • Reduces the risk of tire failure and blowouts

By alerting you when a tire is underinflated, TPMS helps you avoid these issues and maintain a safer, more efficient vehicle.<>

When to Reset and Relearn TPMS

There are a few scenarios where you’ll need to reset and relearn the TPMS on your Toyota Coaster:<>

  1. After rotating or replacing the tires
  2. If a TPMS sensor is replaced
  3. When the TPMS warning light comes on and stays on
  4. If you’re getting inaccurate tire pressure readings

Performing a TPMS reset and relearn periodically, even if there are no apparent issues, can also help keep the system functioning optimally.<>

TPMS Reset vs Relearn: What’s the Difference?

While the terms are often used interchangeably, there is a distinction between resetting and relearning TPMS:<>

  • TPMS Reset: Clearing any warning lights or messages and restoring the system to its default state. This is typically done after inflating tires to the proper pressure.
  • TPMS Relearn: Teaching the TPMS control module the location and unique ID of each sensor in the wheels. This is necessary when sensors are replaced or rotated to new positions.

The specific steps for resetting and relearning TPMS can vary between vehicle makes, models, and years. We’ll cover the general procedures for the Toyota Coaster below.<>
