Scan Tool Relearn Enable Method

NOTE: If using the TPM Sensor Activation Tool to enable the relearn mode, the TPM tool must be used to activate the sensors. When this preferred method is used, 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 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.

NOTE: Be sure all tires have been adjusted to the recommended pressures before beginning learn procedure.

Turn ignition ON.
Using a scan tool, initiate the Tire Pressure Sensors Learn mode. A double horn chirp will sound indicating the Learn mode has been enabled. The left front turn signal will also be illuminated.
Starting with the Left Front tire, active the sensor by holding the antenna of the TPM tool aimed upward against the tire sidewall close to the wheel rim at the valve stem location. Press and release the Activate button and wait for a horn chirp. 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 BCM exits the Relearn mode.
Turn ignition OFF.
