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:
If TPM Sensor Activation Tool (J-46079) 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:
In the following procedures, a TPM Sensor Activation Tool (J-46079) 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:
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.
- Use the driver information center (DIC) to enter the TIRE LEARN mode:
- 2011-13 : Enter the learn sequence from the Tire Pressure menu in the DIC. See Fig 1. Select TPM Learn.
- 2014- : Use the MENU button to select the Vehicle Information Menu in the DIC. See Fig 2. Use the thumbwheel to scroll to the Tire Pressure Menu Item screen, then press and hold the SET/CLR button to begin the sensor matching process. A message requesting acceptance of the process may display. 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.
- Starting with the left front tire, learn the tire pressure using one of the following methods:
- Hold the antenna of the Tire Pressure Monitor Diagnostic 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.
- 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.
- After the horn chirp has sounded and the right front turn signal is illuminated, 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.
