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.

The lower display line has several status indicators- explained later. If a TPM is read that already exists in the TPM Data, then that TPM
Data record will be updated with the new information and placed
at the top of the list just as if a new TPM had been read.
The inverse text (lighter on darker background) indicates the
selected item/ command- use the ‘enter’ key to execute.
Main Menu Page and Navigation Where TPM’s are reread several times, then the number of reads of
that TPM is also available from the USB audit file.The ‘Home’ key always returns to this point.
Other pages exist and are accessed by selecting an item and
using the enter’ key
PC CONNECTION CAPABILITIES
The menu page number (e.g. x/y) on the status line indicates the
menu page or item currently displayed. The first number- x-
indicates the item number selected. The second- y- indicates the
total number of items available.
The Bartec Tech 400 can be connected to a pc for one of two
purposes
1) Present its stored data- Mass Storage Mode
Selected TPM Or Vehicle 2) Update the Tech 400 tool’s software program (e.g. adding
new vehicles) - see additional documentation to use this
process.
This confirms the current TPM selection- either displaying the TPM
type or vehicle make and model.
If no type or vehicle is selected, ‘Unknown’ is displayed.
The Tech 400 contains a database which can ‘look up’ the TPM
type via selection of the vehicle make, model and year. The USB indicator is functional under both circumstances. When
the tool is working in the Mass Storage Mode - the keyboard is
inhibited to maintain existing data integrity.

keys. The selection is completed when the Enter key is pressed.
The tool is compatible with PCs running Windows operating
systems (version XP or 2000).
USB ports can be either version 1 or 2.
Wheel Mode Indicator Results Audit System
This status line indicator confirms the current wheel mode setting- 1
or 4 wheels. The Bartec Tech 400 is capable of presenting all of its stored data
within one or more computer files when connected to a PC via an
USB lead. This is the same ‘Mass Storage Mode’ such as used in USB
memory devices. No extra drivers or software have to be loaded
onto the pc.
SINGLE WHEEL MODE
FOUR WHEEL MODE
The files and the stored TPM Data enable the Bartec Tech 400 to
be used as part of an Auditing System.
The tool automatically goes into Mass Storage Device (MSD) mode
when connected to an active USB port on the pc.
It is not necessary to power up the tool prior to connecting to the
pc - it will power up automatically.

TPM Not Found Response USB Indicator
If the search period expires without reading a TPM then the Bartec
Tech 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
move 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
menu/ 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 permanently storing up to 5 TPM Data
records in 1 wheel mode.
In 1 wheel mode, duplicate successful 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
wheel locations- duplicate successful reads are identified when in
ODB communications mode.
If a repeat read against one wheel position 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
viewed on the pc via the Mass Storage Device feature (use the PC
explorer program)
When the USB lead is removed the USB icon will disappear.
The USB connection provides a limited battery charge capability.
Battery Indicator/ Charging
This status line Indicator provides an indication of the remaining
charge status of the battery.
As different TPM types will ‘use up’ differing amounts of energy, the
indicator can only provide estimates of remaining life left before a
recharge is required
There is plenty of power in the Battery
There is a moderate amount of
power in the battery- charging shortly
is suggested.
There is little power left in the battery-
charging is required.
The battery has almost run out

Once a read is completed:-
The TPM id is briefly displayed, then the tool automatically moves
onto the next wheel position- the arrow moves around the
vehicle:-
Awaiting the next read
Once all 4 TPM’s have been read, results can be viewed,
examined on a pc, or the communications sub menu can be
accessed (see ‘Vehicle Communication’ section.
When there is an insufficient amount of power remaining in the
battery then the Bartec Tech 400 will flash its battery icon for two
seconds, save all of the TPM Data and then power itself off.
When the battery is being ‘fast charged’ the indicator segments
‘walk;’ from left to right- see the charging paragraph.
Test Indicator
This status line Indicator only appears on the select by vehicle
menu. It confirms that a vehicle has been sufficiently selected to
fully identify the TPM type.
If the Indicator is not visible when navigating the vehicle screens,
then pressing the Test Key will read the last TPM Type read/
selected.
Note when selecting by vehicle, the Tech 400 will ‘look ahead’
and display the test indicator when sufficient selection has been
made- this may be prior to all available options (e.g. model, year)
having been navigated.
Results Data Available Indicator
This status line Indicator confirms that TPM data is available for
viewing on the screen (using the View TPM Data command from
the main menu) or via a PC when the Bartec Tech 400 is in its Mass
Storage Device mode (See Audit System on page 23).
The Tech400 only stores up to 5 TPM data records at any one time.
When there is no data present, the TPM Data Indicator will not be
visible.

Charger Connected IndicatorIn 4 wheel mode, TPM data is briefly displayed just prior to the
arrow on the vehicle icon moving round to prompt that the next
wheel should be tested. TPM data is stored for future reference.
This status line indicator confirms a charger is connected. Note
that if both a PC (via USB) and charger are connected, the USB
takes priority
To charge the battery, connect the charger and note the Tech
400 automatically turns on with the charger icon displayed.
From fully discharged, the charging sequence is a short period of
‘pre-charge’, followed by about 2 hours ‘fast charging’ followed
by a ‘topping up’ charge.
Pressing the ESC key will return the user back to the previous
menu/ screen. During the fast charge phase, the indicator segments in the
battery icon will ‘walk’.
TPM Test Modes To maximise battery life (no battery has an unlimited life when
specified by discharge and charge cycles), it is recommended
that once the fast charge phase is complete, the Tech 400 is
further left on charge for a minimum of 1 hour, but no longer than
5 hours.
Once a TPM has been selected, a TPM read can be initiated by
pressing the Test Key.
A TPM read is also initiated using the ‘Enter’ key when at the end
of the vehicle selection menu.
When a read is initiated In 4 wheel mode, a vehicle icon is first
presented to prompt to test the correct wheel as part of an audit
Reduce Pressure Indicator
The example below is of a full vehicle audit. The vehicle was
selected using the ‘Select Vehicle’ menu and set to 4 wheel
mode.
(It is noted that this model provides communications to the
vehicle- see the ‘Vehicle Connection’ section of this document.) This status indicator reminds the user that the chosen TPM (from
vehicle selection) requires a reduction in pressure to activate/test.
The first screen shows that the tool is ready to read the front left
TPM - see the ‘TPM Activation/ Test’ section for the detail of how to
do this
Use magnet Indicator
This status indicator reminds the user that the chosen TPM (from
vehicle selection) requires a magnet to activate/test.
