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 function turns on all the exterior lights
simultaneously. This allows the operator to start the test, exit the vehicle and
do a visual check that all exterior lights function properly. Press ESCAPE
button to end the test and turn off all the exterior lights.
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. Chock the wheels to prevent the vehicle from rolling.
b. Start the engine and check that the brake systems air pressure is
greater than 100 psi.
c. Turn engine off.
d. Release the parking and service brakes and allow the system to settle
(air gauge needle stops moving).
e. Press the ENTER button to start the test.
f. If the air tanks pressure is too low to perform the test (pressure must
be greater than 100 psi), the following messages will appear.
