GMC Acadia: How to Reset TPMS

GMC Acadia: How to Reset TPMS

Posted on November 1, 2019 by Jennifer S. 1 Comment

If the Tire Pressure Management System on the GMC Acadia is not working properly, you may have to reset the system. Follow these steps to re-initialize the TPMS.

The light indicator is a notification to warn you of significantly low air pressure or high-pressure loss in your tires and is NOT to be ignored, as low pressure affects the vehicles overall performance such as: 

  • How the vehicle drives. 
  • Increases the need for fuel. 
  • Tire failure. 

First, Check the Recommended Air Levels Needed: 

  • Refer to the Manufacturer’s Sticker located on the inside of the Driver’s door.  
  • Fill each tire to the recommended PSI/air pressure. 

To Reset the Warning Light Perform the following steps: 

  1. Set your Brake (Optional but Safe). 
  2. Turn the key to the ON position without starting the engine.
  3. Using the Keyless Entry/ Key Fob, press and HOLD the Lock & Unlock buttons at the SAME TIME until the horn BEEPS once. The dash screen should display TIRE LEARN ACTIVE.
  4. Switch OFF the automatic headlights. 
  5. Go to the front of the vehicle where you will see the driver’s side headlight ON. This indicates where to start the relearning process. (At each tire a headlight will be on to direct you).  
  6. Using a writing PEN or the device of your choice, RELEASE some air out of the DRIVER’s side tire FIRST until the horn BEEPS. Be patient as this could take up to 30 seconds for each tire.  
  7. Do the exact same for ALL the tires in this order- Driver, Front Passenger, Right Rear, then Left Rear.   

Thereafter, the menu screen should read TRAINING COMPLETE. If not, start the process again from the beginning.

If TRAINING COMPLETE is displayed, refill each tire to the recommended PSI level once more to finalize your TPMS reprogramming! 

The TPMS warning light on your GMC Acadia should be cleared. However, if the light remains illuminated, keep in mind after tires are inflated/deflated, the outdoor temperature affects how fast the air in the tires will adjust to the proper temperature, this could take a day, 2 or 3, simply be patient and give the tires time to adjust. In addition, if the tire pressure warning light stays illuminated past a week, take it to a repair shop as they may reprogram the system with a professional tool, without a fee. If reprogramming fails, there could possibly be a sensor issue or a tire puncture. 

NOTE: If you are unable to Reset the Tire Pressure Warning Light on the first try, REPEAT the steps. If you are still unsuccessful, contact the dealership for assistance or consult your vehicle user’s manual.

    I’ve done it 2x. It said both times after releasing air, “Service Tire Monitor System.”
    The horn only beeped after the driver side and when i stopped releasing air on the passenger side. Nothing happened for the rear tires.
    Now all 4 readings are blank and i have the indicator light as before and the same message.
