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.
f. You must press and hold brake pedal for 60 seconds, as instructed.
g. Once the brake pressure test is completed the pressure leak test
results are displayed.
