Tire Pressure Sensor Relearn

NOTE: When the wheels have been rotated, or a tire pressure sensor has been replaced, retrain tire pressure sensor.

NOTE: If using the TPM Special Tool (EL-46079 or EL-50448) 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 is 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 is being blocked by another component.

Put the vehicle in ON/RUN.
If the DIC (Driver Information Center) display is minimized, press the SELECT knob to maximize it.
Use the SELECT knob to scroll to the Tire Pressure display screen.
Press and hold the SELECT knob for five seconds to begin the sensor matching process. A message displays confirming to begin the process.
Use the SELECT knob to select YES with the highlighted selection, and press the SELECT knob again to confirm the selection. The horn sounds twice to signal the receiver is in relearn mode and the TIRE LEARNING ACTIVE message displays on the DIC screen.
Starting with the left front tire, activate the tire pressure sensors 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.
- Hold the antenna of the TPM Special Tool (EL-46079 or EL-50448) 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.
After horn chirp has sounded, repeat procedure for the next 3 sensors in the following order: Right Front, Right Rear, Left Rear.
After left rear sensor has been learned, the horn sounds two times to indicate the sensor identification code has been matched to the driver side rear tire and the TPMS sensor matching process is no longer active. The TIRE LEARNING ACTIVE message on the DIC display screen goes off.
