How To Relearn GM TPMS sensors - 2014 Silverado Tire Sensors - Sierra Tahoe Suburban Yukon

Summary

In this video, Cliff from The Sunday Drive demonstrates how to fix warning messages related to the TPMS (Tire Pressure Monitoring System) after upgrading to new wheels and tires on a 2014 Silverado. He walks viewers through the process of relearning the TPMS sensors using a relearning tool, including step-by-step instructions on how to activate each sensor. The tutorial covers putting the truck in accessory mode, using the relearning tool, and confirming the process with a successful beep. The video emphasizes the importance of tire pressure and provides guidance for GM truck owners to sync their TPMS sensors.

Takeaways

• 😀 The video explains how to fix warning messages related to TPMS sensors after upgrading tires and wheels on a vehicle.
• 😀 TPMS stands for Tire Pressure Monitoring System, which uses sensors in the valve stems to detect tire pressure and provide alerts on the dashboard.
• 😀 New TPMS sensors may need to be relearned after upgrading to larger wheels or tires, even if the sensors were transferred from the old wheels.
• 😀 The process shown in the video specifically applies to a 2014 Silverado but can also apply to other GM vehicles with similar systems.
• 😀 To start the TPMS relearn process, engage the parking brake, and turn the vehicle's key to accessory mode (one click without starting the engine).
• 😀 Clear the warning message on the dashboard and navigate to the tire pressure window to begin the relearn process.
• 😀 Press and hold the center check mark on the steering wheel until the horn beeps twice, indicating the truck is in learning mode.
• 😀 The TPMS relearn tool is used to activate each sensor individually by sending a signal to the vehicle from the tool.
• 😀 The order of sensor activation starts from the driver's side, moving to the passenger side, and then to the back, finishing with the driver's side rear sensor.
• 😀 The truck will beep after each sensor is activated, and when the process is complete, the system will give two additional beeps to confirm the successful relearn.
• 😀 After completing the process, the tire pressure readings will be displayed on the dashboard. Make sure to consult your vehicle's manual for the recommended tire pressure for your specific setup.

Q & A

What is TPMS and why is it important?

TPMS stands for Tire Pressure Monitoring System. It is a system that uses sensors in the valve stems of tires to monitor their pressure. It alerts the driver if a tire is over or under-inflated, which is crucial for vehicle safety and fuel efficiency.

What happens when you upgrade to larger tires and wheels on your vehicle?

Upgrading to larger tires and wheels can affect the TPMS sensors, as the new setup might require the sensors to be relearned by the vehicle's system. This is necessary even if the original sensors are transferred to the new wheels.

How can you tell if your TPMS sensors are not transmitting correctly?

If the TPMS sensors aren't transmitting correctly, you will typically see a warning on your dashboard, including a 'Service Tire Monitor System' message and a blinking yellow flat tire symbol with an exclamation point.

What should you do first when attempting to relearn your TPMS sensors?

The first step is to ensure the vehicle is in accessory mode. You should turn the key one click to the accessory position, but do not start the engine.

What should you do after turning on accessory mode in the vehicle?

Once in accessory mode, you need to clear any existing TPMS warnings on the dashboard and navigate to the tire pressure window, where you can press and hold the center check mark button on the steering wheel until you hear two beeps. This will activate the learning mode.

What is the TPMS relearn tool and how does it work?

The TPMS relearn tool is a device used to communicate with each tire's sensor. By activating the tool next to each sensor, it sends a signal to the vehicle to 'relearn' the sensor's position and sync it with the vehicle's system.

How do you use the TPMS relearn tool on the vehicle?

To use the TPMS relearn tool, hold it next to each tire's sensor and press the button on the tool. The truck will beep when it successfully recognizes the sensor. This process is repeated for each tire in the order: driver's side, passenger front, passenger back, and passenger driver side.

What indicates that the TPMS sensor learning process is complete?

The TPMS learning process is complete when the truck emits two beeps after activating the final sensor. This indicates that all sensors have been successfully relearned and synced with the vehicle.

Is it necessary to check the tire pressure after relearning the TPMS sensors?

Yes, after completing the TPMS relearn process, it is important to check the tire pressure. In this video, the presenter runs slightly higher tire pressure than recommended due to the larger tires, but it's always best to consult the owner's manual for the recommended tire pressure for your specific vehicle.

How do you finalize the TPMS relearn process?

To finalize the TPMS relearn process, simply turn off the ignition after the system has successfully recognized all sensors, and the warning messages should disappear.
