Section 2 - Relearn TPMS Systems
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
scan tool (OBDII) relearning procedure.
For manual and scan tool (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.
A scan tool (OBDII) relearn requires the use of a Bosch scan tool paired with the
TPA 300. Follow the dedicated section in this user manual (pg 38) to do the pairing
procedure for the first time. When the two tools are already paired, 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.
Step 1: Put the TPA 300 into
"Connect to scan tool" mode.
Step 3: With the TPA 300, read all
the sensors starting from front left.

Step 2: Select the make, model, year of
the vehicle from the scan tool menu, using
Auto Id or Manual method. Then choose
maintenance test, or special tests, then
choose TPMS Registration.
Step 4: Follow the scan tool on-screen
procedure to register the sensors ID's into
the vehicle's ECU.
