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.
