Understanding TPMS in GMC Terrain

Before diving into the reset procedures, it’s essential to understand what TPMS is and how it works in the GMC Terrain.

What is TPMS?

TPMS is a safety system that monitors the air pressure in a vehicle’s tires. It uses sensors located in each tire to measure pressure and transmit this information to the vehicle’s computer system. If the pressure in one or more tires falls below a certain threshold, the system triggers a warning light on the dashboard.

Types of TPMS in GMC Terrain

GMC Terrain uses a direct TPMS, which means there are physical sensors installed in each wheel. These sensors directly measure the air pressure and temperature inside the tire.

When to Reset or Relearn TPMS

You may need to reset or relearn your GMC Terrain’s TPMS in the following situations:

• After rotating tires
• When replacing one or more TPMS sensors
• After changing wheels
• When the TPMS light stays on even after properly inflating all tires
• Following a battery disconnection or replacement

TPMS Reset and Relearn Procedures for GMC Terrain (2010-2017)

For the first-generation GMC Terrain models from 2010 to 2017, follow these steps to reset and relearn the TPMS:

Manual Relearn Procedure

1. Ensure all tires are properly inflated to the recommended pressure
2. Apply the parking brake
3. Turn the ignition to the “ON” position without starting the engine
4. Using the MENU buttons on the instrument panel, scroll through the options until you reach the “Tire Pressure” submenu
5. Press and hold the SET/CLR button for a few seconds
6. The horn will sound twice, indicating that the tire learn mode is active
7. Starting with the front left tire, use a TPMS scan tool to activate each sensor in the following order: front left, front right, rear right, rear left
8. The horn will sound after each sensor is successfully programmed
9. After the last tire sensor is programmed, the horn will sound twice to indicate the process is complete

Alternative Method (Without TPMS Tool)

If you don’t have access to a TPMS scan tool, you can try this alternative method, although it may not work consistently:

1. Follow steps 1-6 from the manual relearn procedure
2. Instead of using a TPMS tool, start by deflating the front left tire until the horn sounds
3. Repeat this process for each tire in the order: front right, rear right, rear left
4. After the last tire, the horn should sound twice to indicate completion

It’s important to note that this alternative method may not always work and could be less reliable than using a proper TPMS scan tool.
