3/6 RELEARN
To find out which relearn type is available for a vehicle, just turn on the tool and select Relearn.
Or refer to the current coverage list at www.bartecautoid.com > Downloads.
Stationary Relearns:
Stationary Relearns use the vehicles on-board TPMS system to listen for transmissions from
sensors while the vehicle is in a “Learn Mode”.
Once the vehicle is in Learn Mode, use the tool to activate the sensors. The vehicle will listen
for the sensor IDs and learn them to the vehicle.
Active (Drive) Relearns:
Some vehicles can be reset by driving. Refer to the on-screen relearn procedures for details on
how far/long to drive. It can take up to 20 minutes to relearn the sensor IDs.
OBD Relearns:
OBD connection allows the TECH300 to directly program the vehicle electronics module with
sensor IDs.
Note that not all vehicles support vehicle communications modes.
OBD can be connected when all sensors are successfully read and the message “All Sensors
OK” is displayed.
Please use the “Technical Information” menu and select “View Vehicle Info” to find the OBD
location.
Relearn Information:
This contains extra information about the relearn for the selected vehicle, which can assist you
if you have any problems. An example would be for some Toyota and Lexus vehicles which use
a summer and winter tyre set.
After selecting a Relearn method, follow the instructions given by the tool to relearn Sensors.
