BYD TPMS Reset and Relearn: A Comprehensive Guide

Tire Pressure Monitoring Systems (TPMS) are an important safety feature in modern vehicles, including BYD models. They alert drivers when tire pressure is low, helping prevent accidents and improve fuel efficiency. However, when tires are rotated, replaced, or a new TPMS sensor is installed, the system needs to be reset and relearned. This process varies depending on the specific BYD model.

In this comprehensive guide, we’ll cover everything you need to know about BYD TPMS reset and relearn procedures. We’ll discuss which models require it, provide step-by-step tutorials using an OBD scanner tool, and share expert tips for a successful TPMS reset.

Understanding TPMS Reset vs Relearn

Before diving into the specifics for BYD vehicles, it’s important to understand the difference between a TPMS reset and relearn:

  • TPMS Reset: This clears any existing TPMS fault codes and turns off the warning light on the dash. It does not register new sensor IDs or positions.
  • TPMS Relearn: Also known as a registration or reprogramming, this process tells the vehicle the ID numbers, positions, and other data from the TPMS sensors. It’s necessary when rotating tires, replacing one or more sensors, or changing tire positions.

Some vehicles only require a TPMS reset after a tire rotation if the sensors report pressure and temperature but not position. Others require a full relearn so the system knows the new sensor positions.

BYD Models Requiring TPMS Reset and Relearn

Most BYD models 2007 and newer come equipped with a tire pressure monitoring system. Here are the BYD vehicles that may require a TPMS reset or relearn procedure:

  • BYD Atto 3
  • BYD e6
  • BYD Han
  • BYD Qin Pro
  • BYD Song
  • BYD Tang
  • BYD Yuan Pro

The specific process varies depending on the model and year. Some BYD vehicles have an auto relearn function where the TPMS will detect new sensor positions after driving for a period of time. Others require using an OBD scanner tool for relearn.

Consult your owner’s manual or a professional mechanic to determine the correct procedure for your BYD model. Attempting the wrong relearn method could cause TPMS malfunctions.

Performing a BYD TPMS Reset and Relearn

There are three main ways to reset and relearn TPMS on a BYD vehicle:

  1. Stationary Relearn: Put the vehicle into “Learn Mode” through a series of actions like turning the key and pressing the brake pedal. Then use a TPMS activation tool to trigger each sensor in a specific order.
  2. OBD Relearn: An OBD relearn is the fastest and easiest method. It requires a TPMS scan tool with OBD relearn capabilities to write the sensor IDs to the vehicle’s computer.
  3. Auto Relearn: Some newer BYD models can automatically detect and relearn sensor positions just by driving the vehicle for about 10 minutes over 30 mph. However, auto relearn doesn’t always work if a sensor is replaced.

Since OBD relearn is the most common and reliable method for BYD vehicles, we’ll provide a tutorial for that process using an OBD TPMS scanner tool.

What You’ll Need:

  • A TPMS-enabled OBD scanner tool
  • Your BYD vehicle
  • About 10 minutes of time

Step-by-Step OBD Relearn Tutorial:

  1. Park your BYD in a safe location and turn off the engine.
  2. Connect your OBD scanner to the vehicle’s OBD-II port located under the dash. Turn the key to the “On” position but do not start the engine.
  3. Turn on your TPMS tool and wait for it to power up. Select “Relearn” from the main menu.
  4. Select the make, model, and year for your BYD vehicle. The tool may automatically detect this info via OBD.
  5. Starting with the left front tire, use your TPMS tool to scan each sensor in a clockwise order – LF, RF, RR, LR. The tool will display the sensor ID and tire pressure for each.
  6. Once all sensor IDs are captured, the OBD scanner will prompt you to connect to the vehicle and upload the IDs. Follow the on-screen instructions.
  7. If the relearn is successful, the TPMS light on the dash should turn off. You may need to drive the vehicle for a few minutes for this to happen.
  8. If the TPMS light remains on, there may be an issue with one of the sensors. Use your TPMS tool to diagnose the problem.

That’s it! You’ve now successfully relearned your BYD’s TPMS using an OBD scanner tool. Be sure to perform a relearn any time you rotate the tires, change tire positions, or replace a TPMS sensor.

Expert Tips for BYD TPMS Reset and Relearn

While the process is fairly straightforward with an OBD scanner tool, there are a few things to keep in mind for the best results:

  • Check the battery: TPMS sensors run on batteries. If a battery is dead, the sensor won’t transmit and the relearn will fail. Most sensor batteries last 5-10 years.
  • Use the right tools: A basic OBD-II code reader won’t have the capability to relearn TPMS sensors. You need a scanner with TPMS reset and relearn functions.
  • Avoid aftermarket sensors: Many inexpensive, universal aftermarket TPMS sensors aren’t compatible with OBD relearn. Stick to OEM sensors for best performance.
  • Troubleshoot the right wheel: If you get a TPMS error after relearn, the OBD scanner will tell you which wheel position has the problem. This saves time diagnosing the issue.
  • Don’t wait too long: If the TPMS light comes on while driving, check and adjust tire pressure as soon as possible. Driving on underinflated tires is a safety risk and can cause damage.

By following these tips and best practices, you can keep your BYD’s tire pressure monitoring system working properly for a safer ride. Regular tire maintenance and prompt relearns will help you get the most out of this important safety feature.

The Importance of Proper Tire Pressure

Maintaining proper tire pressure is critical for several reasons:

  1. Safety: Underinflated tires have more rolling resistance, build up heat faster, and are more prone to damage or failure. This increases the risk of accidents, especially during adverse weather or at high speeds.
  2. Fuel efficiency: Tires with low pressure require more energy to roll down the road. This makes the engine work harder and consume more fuel. By keeping tires properly inflated, you can improve gas mileage by up to 3%.
  3. Tire wear: Underinflation causes tires to wear faster and unevenly. The shoulders of the tire experience more contact with the road, leading to faster tread wear on the edges. Overinflation can also cause problems, with the center of the tread wearing out first.
  4. Ride comfort: Tires with the correct pressure provide a smoother, more comfortable ride. You’ll experience less road noise and vibration in the cabin.

So what is the proper tire pressure for your BYD vehicle? It varies by model, but most passenger cars have a recommended pressure between 30-35 psi. This info is printed on a placard inside the driver’s door jamb or in the owner’s manual.

It’s best to check tire pressure at least once a month when the tires are cold. Driving heats up the air inside the tires, increasing the pressure reading. Colder outdoor temperatures can cause tire pressure to drop about 1 psi for every 10°F.

If you find a tire more than 2-3 psi below the recommendation, add air until you reach the proper inflation. Don’t forget to check the spare tire as well. And if you’re towing heavy loads or driving in extreme heat, you may need to increase pressure beyond the standard recommendation.

By staying on top of tire pressure and performing TPMS resets and relearns as needed, you’ll enjoy a safer, more efficient ride in your BYD vehicle. The TPMS is there to alert you of problems, but it’s not a substitute for regular tire maintenance.
