Buick Regal: TPMS Reset Procedures

NOTE: The TPMS sensor Relearn procedure must be performed after every tire rotation, BCM replacement, or sensor replacement.

When the tire pressure monitor system detects a significant loss, or gain of tire pressure, the tire pressure monitor indicator icon is illuminated on the instrument cluster and, if equipped, a check tire pressure type message is displayed on the driver information center. Both the indicator icon and driver information center message can be cleared by adjusting the tire pressures to the recommended pressures and driving the vehicle above 25 mph (40 km/h) for at least 2 minutes.

TIRE PRESSURE SENSOR RELEARN

NOTE: If using the TPM tool to activate the sensors, any stray sensor signals will not affect the relearn procedure. In the event a particular sensor's information is displayed on the special tool upon activation but the horn does not chirp, it may be necessary to rotate the wheel valve stem to a different position due to the sensor signal being blocked by another component.

NOTE: If using the Pressure Increase/Decrease sensor activation method, ensure that no other learn procedure is being performed simultaneously or that tire pressures are not being adjusted on another TPM equipped vehicle within close proximity. Stray signals from other TPM equipped vehicles just driving by can be inadvertently learned. If any random horn chirps are heard from the vehicle while performing the learn procedure, most likely a stray sensor has been learned and the procedure will need to be cancelled and repeated. Under these circumstances, performing the TPM Relearn Procedure away from other vehicles would be highly recommended. In the event a particular sensor activation does not cause the horn to chirp, it may be necessary to rotate the wheel valve stem to a different position due to the sensor signal being blocked by another component.

1. Turn ignition switch to ACC position.

2. Using a scan tool or the DIC, select Tire Pressure Sensor Relearn. The horn sounds twice to signal the receiver is in relearn mode and the TIRE LEARN or TIRE LEARNING ACTIVE message displays on the DIC screen. To activate the sensor learn procedure using the DIC, see below:

NOTE: Driver Information Center (DIC) Controls are different according to model year. See appropriate procedure below:

2011-13 Models:

1. Use the MENU button on the turn signal lever to select the Vehicle Information Menu (Menu 2). See Fig. 1.
2. Use the thumbwheel (or up and down arrows) to scroll to the Tire Pressure Menu Item screen.
3. Press and hold the SET/CLR button to begin the sensor matching process. A message requesting acceptance of the process may display. If requested, press the SET/CLR button again to confirm the selection.

2014 and Later Models:

1. Make sure the Tire Pressure info page option is turned on. The info pages on the DIC can be turned on and off through the Settings menu.
2. Use the DIC controls on the right side of the steering wheel to scroll to the Tire Pressure screen under the DIC info page. See Fig. 2.
3. Press and hold the Set/ Reset button (check symbol) located in the center of the DIC controls.

NOTE: The horn sounds twice to signal the receiver is in relearn mode and the TIRE LEARNING ACTIVE message displays on the DIC screen.

3. Starting with the left front tire, activate the tire pressure sensor using one of the following methods:

• Increase/decrease the tire pressure for 8-10 seconds then wait for a horn chirp. The horn chirp may occur before or up to 30 seconds after the 8-10 second pressure increase/decrease time period has been reached. Once the horn chirp has sounded, the sensor information is learned and the turn signal in the next location to be learned will illuminate.
• Hold the antenna of the tire sensor activation tool aimed upward against the tire sidewall close to the wheel rim at the valve stem location. Press and release the activate button.

  Ensure that the transmit indicator on the special tool indicates that the sensor activation signal is being transmitted. Wait for a horn chirp. If the horn does not chirp, repeat the sensor activation sequence with the tool. Once the horn chirp has sounded, the sensor information is learned and the turn signal in the next location to be learned will illuminate.

4. After horn chirp has sounded and the right front turn signal is illuminated, repeat procedure for the next 3 sensors in the following order: Right Front, Right Rear, Left Rear.

5. After left rear sensor has been learned, a double horn chirp will sound, indicating all 4 sensor IDs have been learned. Turn ignition switch to OFF position. Adjust all tire pressures to specification.
