23. Type of TPMS systems installed on vehicles
As for the sensors self-learning functions it is possible to classify vehicles in 3 categories.
Vehicle with
identification code self-
learning of a new sensor
or the wheel position
Vehicle with identification
code self-learning of a
new sensor but not of the
wheel position
Vehicle without self-
learning function
According to the type of vehicle the software provides indications about how to
complete the TPMS sensor replacement procedure.
To carry out the coding functions it is not necessary to have the EOBD cable when the
sensor reads the code through Radio Frequencies. The TPMS CONNECT EVO and the
EOBD accessory do not need to be near the sensor at the same time and connected to
the EOBD socket thus avoiding the need of very long cables.
Model A
The vehicle electronics allows learning the new code of a new
sensor or the new position of the sensor after one wheel
rotation. Usually this procedure is carried out by driving the
vehicle for nearly 10 km at the end of which any warning lights
turn off.
Yet on some vehicles it is necessary to codify the new
identification codes if all 4/5 sensors are replaced at the same
time.
Model B
The vehicle is able to learn the new sensor position after one
wheel rotation, but can not learn the ID code of a new sensor.
To do that it is necessary to connect to the vehicle EOBD
diagnosis socket and to enter the sensor ID code
Model C
Both after one wheel rotation and after replacing one or more
sensors it is necessary to connect to the OBD diagnosis socket
to set the wheel position and/or the new sensor ID code.
