GMC Sierra: How to Reset The Tire Pressure System

GMC Sierra: How to Reset The Tire Pressure System

Posted on November 21, 2019 by Jennifer S. Leave a Comment

If the Tire Pressure Management System in the GMC Sierra is not working properly, you may have to reset the system. Follow one of the Options below 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. 

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.

  • Option 1: Via the Keyless Remote
  • Option 2: Via the Knob Control

Option 1: Via the Keyless Remote

  1. With your vehicle in the ON position without starting the engine. 
  2. Press the LOCK and UNLOCK buttons on your vehicle’s Keyless Remote/ Key Fob at the same time. The horn will blow TWICE to signify this was done correctly.
  3. Using a writing PEN or any 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.  
  4. Do the exact same for ALL of the tires in this order- Driver, Front Passenger, Right Rear, then Left Rear.   
  5. Refill each tire back to the recommended PSI Levels.

You are all SET! The warning light should be OFF. 

However, if not, keep in mind, after tires are inflated, the outdoor temperature affects how fast the air in the tires will adjust to the proper temperature, this could take minutes, 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, you will need to have your vehicle serviced as there could possibly be a sensor issue or a tire puncture. 


Option 2: Via the Knob Control

With your vehicle in the ON position without starting the engine. 

  1. Turn the knob from AUTO to OFF really Fast three times. The horn will blow ONCE to signify this was done correctly.
  2. Using a writing PEN or any 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.  
  3. Do the exact same for ALL of the tires in this order- Driver, Front Passenger, Right Rear, then Left Rear.   
  4. Refill each tire back to the recommended PSI Levels.
