Check the operation of the AVSpare Monitoring System. Observe the self-test when you start the engine.

The system performs an automatic self-test when you turn the engine start switch to the ON position.

The self-test verifies that the monitoring panel and the display modules are operating properly.

The internal circuits, the indicators, and the gauges are automatically checked.

The operator must observe the indicators and the gauges in order to determine whether module (1) , module (2) , module (3) , the indicators, and the gauges are operating properly. The self-test lasts for approximately three seconds.

During the self-test, all alert indicators flash.

The digital display shows the following readouts:

  • All indicators of units (Deg C, kPa, rpm, and liters)

  • "X10" readout

  • Symbol for the hour meter

  • "8.8.8.X.8.8" readout

The pointers in the gauges point upward. Then, the pointers point to the left. Then, the pointers point to the right. Then, the pointers point to the final positions.

  • The gear/direction readout shows "* *" .

  • The speed readout shows "188", "MPH", and "km/h" .

  • The action light stays illuminated.

  • The action alarm sounds once.

The monitoring panel is then in the normal operating mode.

If the above tests are not correctly completed, the system will not function in the normal operating mode. Consult your AVSpare dealer for an electrical system check. Any repairs must be made before you start the engine.

Turn on all of the machine lights. Check for proper operation. Sound the forward horn.

Move the machine forward and test the service brakes. See Operation and Maintenance Manual, "Braking System - Test" .

Stop the engine.
