Tire Pressure Sensor Learn

NOTE: Once the learn mode has been enabled, each of the sensor's unique identification (ID) codes can be learned into the RCDLR's memory. The RCDLR must learn the sensor IDs in the proper order to determine correct sensor location. The first learned ID is assigned to left front, the second to right front, third to right rear and forth to left rear.

NOTE: In the following procedures, a TPM Special Tool (EL-46079 or EL-50448) may be used in place of increasing/decreasing pressures to enable sensor. To use, place activator antenna against the tire sidewall close to the wheel rim at the valve stem location, then press and release the ACTIVATE button.

NOTE: If TPM Special Tool (EL-46079 or EL-50448) is used, and vehicle is having trouble entering relearn mode, check batteries in activation tool. Low batteries may allow some functions to work, but not allow vehicle to perform learn function. When the internal battery is fresh (fully charged), the indicator is "full" or all dark. When the battery is depleted, the indicator shows "empty" or all light. The placement of the TPM Sensor Activation Tool (J-46079) is critical. If the scan tool antenna is not placed perpendicular to the wheel wall and close to tire pressure valve stem, it may not properly activate the tire pressure sensor.

NOTE: The TPM Special Tool (EL-46079 or EL-50448) can be used during the learn procedure. Press and release the "ACTIVATE" key button 1 second, this is will activate the activation cycle. The Activation cycle will force the tire pressure sensor to transmit their IDs.

NOTE: Before proceeding with the steps below, ensure that no other sensor learn procedure is being performed simultaneously and that no tire pressures are being adjusted on another TPM equipped vehicle within close proximity.

IMPORTANT: In the event that 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.

Ignition ON, initiate the TPM Learn Mode using one of the following procedures:
- Using a scan tool, initiate the TPM Learn Mode. A double horn chirp will sound indicating the Learn Mode has been enabled. The left front turn signal will also be illuminated.
- Using the Driver Information Center (DIC):
  - 2011-15 :
    1. Set the parking brake.
    2. Put the vehicle in ON/RUN and place the vehicle in P (Park).
    3. If the DIC display is minimized, press the SELECT knob to maximize it. See Fig 1.
    4. Use the SELECT knob to scroll to the Tire Pressure display screen.
    5. Press and hold the SELECT knob for five seconds to begin the sensor matching process. A message displays confirming to begin the process.
    6. 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.
    7. Proceed to next step.
  - 2016- :
    1. Set the parking brake.
    2. Place the vehicle in ON/RUN.
    3. 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.
    4. 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.
    5. Press and hold the Check Mark (Set/ Reset) button located in the center of the DIC controls. The horn sounds twice to signal the receiver is in relearn mode and the TIRE LEARNING ACTIVE message displays on the DIC screen.
    6. Proceed to next step.
Starting with the left front tire, active the sensor by holding the antenna of the TPM 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.
After the horn chirp has sounded and the right front turn signal is illuminated, repeat procedure 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.
