Lamp Test

LAMP TEST
This test allows the user to control ALL the warning/indicators associated with the Instrument Cluster. It can be used to check the indicator circuits and the serial data link to the Instrument Cluster. When using this test, ALL the indicators associated with the Instrument Cluster will be ON. This test is similar to a BULB CHECK.
