equipped) and the AutoFresh air port opens and closes (if equipped).
6. The remainder of the Pretrip tests will run automatically and take 7 to 15 minutes. The percent of Pretrip that
has been completed is displayed in the status bar under the test description information.
7. “PRETRIP PASS”, “PRETRIP FAIL IN TEST ##” or “PRETRIP FAILED AND COMPLETE” will be displayed
at the end of the testing. The “PASS” message will display until a key is pressed. The Pretrip test “FAIL”
results message will display until the alarms are cleared.

Test 1 - Display Test:
The control system activates the buzzer. Also, the amber light on the light bar is illuminated (if equipped) and the
AutoFresh air port opens and closes (if equipped). This test will last 5 seconds. This portion of the Pretrip requires
that the operator determines PASS or FAIL. Anything that fails during this test should be repaired at the conclusion
of the Pretrip cycle. Pretrip will continue regardless of the outcome of this test.
Test 2 - 12VDC Electrical Component Amperage Check -
Test 2 will check the amperage (current) draw of the
following components:
• Battery Amp Draw (All Components Turned Off).
• AutoFresh Air Exchange Relay
(AFAR - if equipped)
• Clutch (CLH)
• Font Unloader Solenoid (UL1)
• Rear Unloader Solenoid (UL2)
• SV1
• SV2
• SV4
• Preheat Circuit (EPH)
• Fuel Solenoid (FSA)
Each component will be individually checked for proper current draw. An alarm will be activated for any component
not drawing amperage in the expected range.
Test 3 - Temperature Sensor Check -
Check the condition of all of the system temperature sensors.
Test 3 will last approximately 5 seconds. If a problem is detected with any of the sensors, the corresponding alarm
will be activated.
Test 4 - Warm Up -
The engine is started automatically and the ambient air sensor is read.
If the ambient temperature is above +32°F (0°C), the unit will operate in the “Cool Pretrip” Mode. If the ambient
temperature is at or below +32°F (0°C), the unit will operate in the “Heat Pretrip” Mode.
In the
Cool Pretrip
Mode, the unit will operate in two cylinder Low Speed Cool. The compressor suction and dis-
charge pressures will be tested. Appropriate alarms will be displayed if any problem is detected. Test 4 in Cool Pre-
trip will last approximately 60 seconds.
