Self Test
The Dash Panel Cluster will initiate a self test when the engine key start switch is moved to the START position. The gauge needles will move to the maximum right position and will remain at the maximum right position for 0.5 seconds. The gauge needles will then return to minimum left. This prevents the gauge needles from circling to the bottom side of the gauge (such as when the display is inverted). A self test begins after the hardware is tested.The ECM controlled test of the Dash Panel Cluster will begin after the hardware is tested. The test will proceed while the engine key start switch remains in the RUN position. The test is initiated because the Dash Panel Cluster is not required to operate through engine cranking.The duration of the ECM-controlled test is 3 seconds. During this time, the following functions will be performed:
The gauge needles are set to the minimum position. The needles move smoothly from the minimum value to the maximum value during the test.
The icons and the segments are illuminated. The illumination continues for the duration of the self test.
All LED indicators are illuminated for testing.
The alarm mode activates at the beginning of the self test mode. The alarm state remains ON for 1 second.After completion of the self test, the Dash Panel Cluster goes to normal mode operation. Normal mode operation could include subsequent machine tests.
