TPS is assembled on each tire to check tire air pressure. This system only turns on warning lamp regardless of TPS position even if air pressure of one tire becomes less than warning pressure. So, IDs registration is not necessary in case of rotation or replacement of tires. However, IDs registration is necessary when shipping vehicles, TPS is replaced due to Sensor break/failure or Low battery, or Receiver is replaced.

Important:  Before proceeding with the procedure below, ensure that no other learn procedure is being performed simultaneously.

1. Turn the ignition switch to ON, with engine OFF and apply the parking brake.
2. Put receiver into TPM Learn Mode using Scan tool.

•	Initiate the procedure by following the menu selections.

•	If successful, double horn chirp sound and flashing low tire indicator (MIL) will indicate Learn Mode has begun.

3. Within 2 minutes, go to the LEFT FRONT tire. Trigger the tire sensor to send a learn message (use any method described below). If successful, a horn chirp is heard.
4. After the horn chirp sounds, proceed as in step 3 for the next 3 sensors in the following order:

4.1.	Right front

4.2.	Right rear

4.3.

Left rear

5. After the left rear sensor is learned, a double horn chirp will sound indicating all sensor IDs have been learned and low tire indicator (MIL) will turn off.
6. If one of the tire sensors does not program within the 2 minute interval, the system will automatically exit programming mode and steps 2 through 6 must be repeated.
7. If air was added or removed to trigger a tire sensor learn message, then the tire pressures should be adjusted to the correct placard cold tire pressures at this time.

There are several ways to force a tire sensor to send a Learn message.

Delta Pressure

While the tire is stationary and when the air pressure changes rapidly by at least 1.2 psi, the sensor will transmit a Learn Mode-Pressure Triggered message. Inflating or deflating the tire until a horn chirp is heard will ensure that the learn happened.

Using J-46079

Each sensor has an internal low frequency coil. When the J-46079 is used in activate mode, it produces a low frequency transmission that activates the sensor. The sensor responds to an low frequency activation by transmitting in learn mode.
