TEST OVERVIEW
The Switch Monitor Function provides a means to monitor the operation of various switches and their related input circuits to the vehicle control modules.
View: Special Service Tool (SST)-49 H018 9A1:
Checking switch operation is possible by viewing a monitor lamp on the Special Service Tool SST.
- When a particular switch is activated, the monitor lamp is illuminated.
- When the switch is deactivated, the monitor lamp should turn OFF.
Fig.1 Switch Operation Chart:
If the monitor lamp fails to illuminate or fails to turn OFF for any given switch under the conditions in Fig.1, then the switch and related circuit should be tested further.
