HDS Inputs and Function Test

Certain inputs happen so quickly that the Data List on the HDS cannot update fast enough. Hold the switch that is being tested while monitoring the Data List. This should give the HDS time to update the signal on the Data List.

Because the HDS software is updated to support the release of newer vehicles, it is not uncommon to see system function tests that are not supported.

Make sure that the most current HDS software is loaded.
