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.
• | Initiate the procedure by following the menu selections. |
• | If successful, should double horn chirp sound and flashing low tire indicator(MIL) will indicate Learn Mode has begun. |
4.1. | Right front |
4.2. | Right rear |
4.3. | Left rear |
There are several ways to force a tire sensor to send a Learn message.
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.
Holding the tool near the tire stem will force the sensor to transmit a Learn Mode-LF Triggered message.
Several manufacturers produce a Low Frequency (125 KHz) tool that can activate the sensors in the same way as the SPX tool.
