PRE-TRIP ASSISTANT (option)
The Pre-Trip Assistance option is a tool to assist
the driver in completing the pre-trip inspection of
the vehicle. This option is not a substitute for a
complete pre-trip inspection. If any system of the
vehicle does not pass inspection, the error must
be corrected before operating the vehicle. The
available pre-trip tests include the Exterior Light
Inspection check, and the Air Leakage check.
1. Exterior Light Inspection
The Exterior Light Inspection check repeatedly
turns all exterior lights on/off for the vehicle. This
allows the operator to start the test, exit the
vehicle and do a visual check that all exterior
lighting is functioning properly.
2. Air leakage Monitor
The Air Leakage check allows the driver to
accurately measure the amount of air pressure
drop in the front and rear brake air systems.
After selecting this test from the DID, you are
prompted to apply the service brake for 60
seconds. After applying and holding the service
brake for 60 seconds, the DID will display the
amount of pressure drop in the brake system.
Before starting the test through the DID,
complete the following:
a. Start the engine and check that the brake
systems air pressure is greater than 100
psi.
b. Turn engine off.
c. Release the brakes and allow the system
to settle (air gauge needle stops moving).
d.
Press the ENTER button to start the test.
e.
If the air tanks pressure is too low to
perform the test (pressure must be
greater than 100 psi), the following
messages will appear.
