4. TPMS Activation
The MaxiTPMS
®
TS401 is a hand held tool used to activate all
magnetic, frequency, and tire deflation triggered sensors used on
vehicle tire pressure monitoring systems to get information such as
sensor ID, tire pressure, tire temperature, sensor battery, and
frequency. It also sends the sensor data to vehicle’s ECU to let the
ECU learn the positions of sensors whenever tires and wheels are
rotated or sensors are replaced.
There are two means of activating a TPM sensor:
A. Vehicle Selection--To activate the sensor by selecting vehicle
make, model and year.
B. Latest Scan--The TPMS tool automatically records the latest
activated sensor and it activates the sensor by using the wave
signal of the latest trigger event. So Latest Scan is very useful for
technicians to wake up sensors of the same vehicle.
 All software screens shown in this manual are examples.
Actual test screens may vary for each vehicle being tested.
