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. The needles will remain there for 0.5 seconds. The gauge needles will then be returned to minimum left. This prevents the gauge needles from circling to the bottom side of the gauge. This would happen if 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. This would happen because the Dash Panel Cluster is not required to operate through engine cranking.The duration of the ECM controlled test is three 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 one second.After completion of the self test, the Dash Panel Cluster goes to normal mode operation. This could include subsequent machine tests.
