TPM Learn Procedure
WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
If using the scan tool to enable the learn mode, the J-46079
must be used to activate the sensors. See Special Tools . When this preferred method is used, any stray sensor signals will not affect the learn 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 is being blocked by another component.
If using the keyless entry transmitter to enable the learn mode, the J-46079 or Pressure Increase/Decrease Method may be used. See Special Tools . Before proceeding with this 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 Learn Procedure away from other vehicles would be highly recommended. In the event a particular sensor pressure increase/decrease 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 is being blocked by another component.

Preferred Scan Tool Learn Enable Method
- Using a scan tool, initiate the TPM Learn Mode. A double horn chirp will sound indicating the Learn Mode has been enabled.
- Starting with the left front tire, active the sensor by holding the antenna of the J-46079 aimed upward against the tire sidewall close to the wheel rim at the valve stem location. See Special Tools . Press and release the Activate button and wait for a horn chirp. Once the horn chirp has sounded, the sensor information is learned.
- After the horn chirp has sounded, repeat step 2 for the remaining 3 sensors in the following order:
- Right front
- Right rear
- Left rear
- When the left rear sensor has been learned and a double horn chirp has sounded, the learn process is complete and the RCDLR exits the learn mode.
- Ignition OFF, adjust all tires to the recommended pressures. Refer to Vehicle Certification, Tire Placard, Anti-Theft, and Service Parts ID Label .
Alternate Keyless Entry Transmitter Learn Enable Method
- Ignition ON, initiate the TPM Learn Mode by simultaneously pressing the keyless entry transmitter lock and unlock buttons until a double horn chirp sounds indicating the Learn Mode has been enabled.
- Starting with the left front tire, learn the tire pressure using one of the following methods:
- Hold the antenna of the J-46079 aimed upward against the tire sidewall close to the wheel rim at the valve stem location. See Special Tools . Press and release the activate button and wait for a horn chirp.
- 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.
CAUTION: Over inflating tires may cause personal injury or damage to the tires and wheels. When increasing tire pressure do not exceed the maximum inflation pressure as noted on the tire sidewall. - After the horn chirp has sounded, repeat step 2 for the remaining 3 sensors in the following order:
- Right front
- Right rear
- Left rear
- When the left rear sensor has been learned and the double horn chirp has sounded, the learn process is complete and the RCDLR exits the learn mode.
- Ignition OFF, adjust all tires to the recommended pressures. Refer to Vehicle Certification, Tire Placard, Anti-Theft, and Service Parts ID Label .
