Pre-Trip Check

When one of the preconditions defined to
start the pre-trip check is met, the TPM
display enters into a pre-trip check routine
and the screen shown below appears. The
preconditions to initiate the pre-trip are: Park
brake removed Or No activity on the display
menu keys for a defined time (Key pressed
timeout).
After a pretrip, the display is in a "drive"
mode with bottom menu replaced by the
alarm status. The display remains in this
T8061962
mode until one of the following occurs: A
menu key is touched while the park brake is
applied, or the park brake does a transition
from released to park brake applied.
During the pre-trip check, the pressure
readings for the different wheels become all
available.
The pre-trip check ends, either when: the
pressure readings have been received for
all running wheels or the pre-trip check
maximum time has elapsed. It was selected to
provide sufficient time for all wheel sensors
to wake-up and send a first reading.
The pre-trip check is aborted and the bottom
menu reappears if the park brake was active
and the user press one of the menu keys.
