SPECIFICATION/ FUNCTIONALITY
The Tech 400 is a hand held tool to test wheel sensors used on
automobile Tire Pressure monitoring systems.
An LCD display and keypad allows rapid configuration of the tool
to ensure compatibility with all TPM (Tire Pressure Monitor) types
commonly experienced.
TPM sensors are checked for RF transmission (multiple frequencies)
and fully decoded for id, pressure, temperature, battery status
(dependant upon data provided by the TPM).
Two methods of selecting the correct TPM are provided- either
directly from a TPM manufacturer menu, or via a vehicle make,
model and year selection (using a built in vehicle to TPM look up
table).
Two methods of vehicle testing are available- either 1 wheel or 4
wheel. The 4 wheel method provides a vehicle icon on the screen
to give user prompts for each wheel- an audit of a vehicle.
Results can be viewed on the screen or viewed, printed and saved
on a computer (via a USB port). If a TPM is not found (faulty) then a
replacement catalogue number is displayed (when in vehicle
select mode only)
An OBD (On Board Diagnostic) interface can be connected to the
Tech 400 to communicate with the vehicle electronics. This allows
programming of the TPM’s into the vehicle and resetting of TPM
dashboard displays. No vehicle driving is necessary. The exact
features available are dependant upon the vehicle make and
model.
The Tech 400 is self powered using a rechargeable battery- a
charger is provided.
The Tech 400 has a settings menu to configure units of
measurement- e.g. Fahrenheit and Celsius/ PSI & Bar.
The Tech 400 can be upgraded (e.g. as new vehicles become
available) directly via the USB port.

TPM Not Found Response USB Indicator
If the search period expires without reading a TPM then the Bartec
Te
ch 400 will emit a single Audible Beep and indicate on the
display that no TPM was found.
This status line indicator confirms the Tech 400 is connected to the
USB port of a personal computer.
In 4 wheel mode, the test prompt arrow will not automatically
mo
ve to the next wheel. This helps to do a repeat test to confirm
the TPM failure. Use ‘Down’ key to move to the next wheel.
It has two states:
Indicates an initialisation of
communication with the pc
Indicates that communication
has been established.
If the TPM has been selected via a vehicle menu, the internal
database automatically displays the catalogue number of the
replacement part (if it is available).
Pressing the ESC Key will return the user back to the previous
me
nu/ screen.
The TPM Data will still be stored but will indicate that the TPM Failed
to
Read.
TPM Data Storage
The Tech 400 is capable of permane
ntly storing up to 5 TPM Data
records in 1 wheel mode.
In 1 wheel mode, duplicate successf
ul reads will update any
already stored records.
More than 5 reads will cause the last record to be overwritten.
In 4 wheel mode- where data records are stored against specific
whe
el locations- duplicate successful reads are identified when in
ODB communications mode.
If a repeat read against one wheel p
osition is required, then the up
arrow key should be used to force the screen pointer to the wheel
requiring a repeat.
Once communication has been established, results data can be
v
iewed on the pc via the Mass Storage Device feature (use the PC
explorer program)
