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)
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 indicat
ion of the remaining
charge status of the battery.
As different TPM types will ‘use up’ differing amounts of energy, the
indicat
or 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
