 There should be continuity between terminals No. 1 and No. 2 when the battery positive terminal is
connected to terminal No. 4, and the battery negative
terminal is connected to terminal No. 3.
 There should be no continuity between terminals No. 1 and No. 2 when power is disconnected.

22-88Multiplex Integrated Control System
System Description (cont’d)
Certain inputs happen so quickly that 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 for newer vehicles it is not uncommon to see system function tests that are not
supported.
Make sure that the most current software is loaded.
