Section 2 – Relearn TPMS system
After selecting the Make-Model-Year of the vehicle, the tool systematically displays which relearn
procedure is required for that particular vehicle: automatic, manual or OBDII relearning procedure.
For manual and OBDII relearn procedures, follow the instructions displayed on the tool screen. For
vehicles with an automatic relearn procedure, where the TPMS system is automatically reset when
driving the car, it is recommended to trigger each wheel sensor one final time, to make sure they
are in correct working order.
An OBDII relearn requires the use of a Bosch scan tool paired with the TPA 300. Follow the
dedicated section in this user manual to do the pairing procedure for the first time. When the two
tools are already paired you have to use the "Connect to scan tool" mode from the TPA 300 main
menu. All the other steps – except the sensor reading – are made directly from the Bosch scan
tool.
I - Put the TPA 300 into "Connect to
scan tool" mode.
III - With the TPA 300, read all the
sensors starting from front left.
UM-BTPA1-6
II - Select the make, model, year of the
vehicle from the scan tool menu.
IV - Follow the scan tool on-screen procedure to
register the sensors IDs into the vehicle's ECU.
