The Switch Diagnostic Test

If during the course of operations certain switch functions appear to be non-responsive or

intermittent, use the transmitter diagnostic switch test for switch troubleshooting. The switch

test provides a method to test transmitter switches without actually operating the locomotive.

Press F1 and F4 simultaneously to enter the diagnostic switch test. Once in the test mode,

rotating or activating the switches will show a corresponding change in the display groups

identified in Fig 7-3. Refer to the tables below for switch to display indicator mapping.

To exit diagnostic switch test, cycle power.
