Once the reread mode is enabled, the identification code for each sensor will be read into the body control module memory. When a sensor identification code is read, the body control module causes the horn to chirp to indicate that the sensor has sent an identification code and that it has been received and read by the body control module. The body control module must read the sensor identifiers in the correct order to determine the correct sensor location.▲The first code read is assigned to the left front position, the second to the right front position, the third to the right rear position and the fourth to the left rear position. The turn signal lights will illuminate separately to indicate the correct order of the read positions.①Use the EL-50448 or equivalent to diagnose sensor functionEach sensor has an internal low frequency coil. When tire pressure monitoring is used in enable mode, a low frequency transmission signal will be generated to activate the sensor. In read-in mode, the sensor responds to the low-frequency activation by transmitting the signal. In Tire Pressure Monitor Read-In Mode, when the Body Control Module receives a Read-In Mode transmission signal, it assigns the sensor identification code to the vehicle location corresponding to its read-in sequence.②Sensor Function - Using the Pressure Increase/Decrease MethodIn standstill mode, each sensor takes a pressure measurement sample every 30 seconds. If tire pressure increases or decreases by more than 8.3 kPa (1.2 psi) from the last measurement, a re-measurement will be taken immediately to confirm the pressure change value.
