9. OPERATING INSTRUCTIONS
9.1. TPA300 OVERVIEW
The Bosch TPA 300 offers the versatility to work in conjunction with a Bosch scan tool or as a
stand-alone TPMS tool, depending of the task you want to achieve.
Stand-alone mode can be used to read, program and copy TPMS sensors, test RKE, save and
retrieve jobs, and setup the tool.
Connect to scan tool mode offers the ability to connect wirelessly to a Bosch scan tool and to
register the TPMS sensors IDs into the vehicle ECU.
9.2. SERVICE PROCEDURE
Section 1 - Read Sensor Test
Before servicing the tires/wheels, using your TPMS TOOL, trigger each of the vehicle's sensors to
make sure they are working properly. You can either use the standalone or the connect to scan
tool mode to select the make, model, and year of your vehicle.
1 Start FL
4 End RL
FR 2
RR 3
I- Select the Make, Model,
Year of the vehicle.
II - Hold the tool facing the tire flank
near the valve.
III - Read all the sensors
starting from front left.
This will eliminate the liability associated with replacing previously damaged or defective sensors.
This procedure will not change the vehicle settings because the vehicle has yet to be put into learn
mode. This procedure allows you to quickly identify damaged or defective sensors, because some
vehicles do not report a damaged or defective sensor condition on the instrument cluster for up to
20 minutes.
Note: With some vehicles, if the vehicle is in “learn mode” the vehicle will also confirm that the
TPM sensor has communicated to the ECU with a series of horn beeps.
Note: If the sensors do not trigger, please refer to the Troubleshooting section of this Guide.
For vehicles that require relearn procedure, please see Section 2.

TPA 300 user guide
UM-BTPA1-6 8/54 User guide BOSCH TPA 300
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.
II - Select the make, model, year of the
vehicle from the scan tool menu.
III - With the TPA 300, read all the
sensors starting from front left.
IV - Follow the scan tool on-screen procedure to
register the sensors IDs into the vehicle’s ECU.

TPA 300 USAGE IN STANDALONE MODE
IMPORTANT:
TPA 300 Standalone mode is used to read, program and copy TPMS sensors, test
RKE, save and read recorded jobs, and setup the tool. If you need to register the
TPMS sensor IDs into the vehicle ECU you must use the TPA 300 Connect to scan
tool mode. See this user manual dedicated section to learn how to operate this
mode.

1. CHECK TPMS SENSORS
This mode is to trigger all the TPMS sensors on the vehicle.
Warning! For best sensor triggering, hold the tool
against the tire sidewall right above the sensor.

TPMS sensor reading problems –Troubleshooting guide
1) The vehicle has no TPMS sensors even if a metal stem is present. For example,
Schrader valves can look the same as TPMS valves.
➔Check for the presence of TPMS sensors on the vehicle. You can also use your
TPMS tool to check the type of TPMS valve (direct or indirect) mounted on your
vehicle. Caution, indirect TPMS systems operate without sensors mounted in
the tires.
➔If the vehicle you are checking was not originally fitted with TPMS sensors,
your tool will tell you clearly through the message "Indirect TPMS".
2) The TPMS sensor or ECU (TPMS computing unit) may be damaged or defective.
➔Check all these elements separately in order to eliminate the possible origin of
the problem.
3) The TPMS sensor only responds to a certain frequency.
➔Check the communication frequency of the vehicle's TPMS sensors. This is
generally 433 MHz for Europe and 315 MHz for the United States and Japan.
Make sure the vehicle is not a vehicle imported from another region since it may
be set to a different frequency.

TPA 300 user guide
UM-BTPA1-6 14/54 User guide BOSCH TPA 300
4) The TPMS sensor mounted in the tire is not the correct reference.
➔Each vehicle model –each version even –can be fitted with a different make
and model of TPMS sensor. Make sure that the vehicle is fitted with the correct
TPMS sensor P/N.
5) Your TPMS tool may require a software update.
➔If all the previous points check out, you may have a vehicle that is not yet in the
TPMS tool's database. In this case simply update your device using the TPMS
Tool PC software. Refer to the dedicated section of this user manual for this.
6) Your TPMS tool is damaged or defective.
➔If all the previous points check out, your TPMS tool may be damaged or
defective. In this case, contact your local dealer.

2. PROGRAM TPMS SENSORS
The TPA 300 works with most known aftermarket universal programmable sensors, with
the options to create the new sensor IDs and/or duplicate sensor ID(s) from original
sensor(s).
To access the program sensor function, you must start by selecting the Make/Model/Year
of the targeted vehicle.
Go to the program sensor icon located at the very bottom of the trigger screen (car
