Operating Instructions

10.1. TPA 300 Overview
The Bosch TPA 300 offers the versatility to work in conjunction with a Bosch scan
tool or as a stand-alone TPMS tool.
Stand-alone mode can be used to read, program and copy TPMS sensors, test RKE
(Remote Keyless Entry), 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.
10.2. Service Procedure
Section 1 - Read Sensor Test
Before servicing the tires/wheels, using the TPMS tool, trigger each of the vehicle's
sensors to make sure they are working properly. Either use the standalone or the
connect to scan tool mode to select the make, model, and year of the vehicle.
Step 1: Select the Make, Model,
Year of the vehicle.
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 quickly identifies 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, see Section 2 on page 10.
