SWITCH MONITOR FUNCTION TEST OVERVIEW
Individual switches can be inspected by the special service tools (SST)s (Self-Diagnosis Checker and System Selector).

TEST PREPARATION
The TEN terminal of the data link connector must be grounded and the ignition switch turned to ON (engine off). If any switch remains activated, the monitor light will be illuminated. If switches are deactivated the monitor light should be OFF.

8. Verify that the monitor light illuminates when each switch is made to function as described. If the monitor light 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.

Deactivated Switch Test:

DEACTIVATED SWITCH TEST
Set conditions to deactivate each switch.
Is the monitor light OFF with all switches deactivated?
