Switch Monitor Test

PURPOSE
The Switch Monitor Test checks input signals sent from the Powertrain Control Module (PCM).

DESCRIPTION
The Switch Monitor Test is a unique and separate test from the Key On Engine Running (KOER) Diagnostic Test Mode. This test is performed by actuating a series of switches and verifying their operation and input signals.

All switches must be OFF at the beginning of the test and only one switch at a time must be actuated during the test.
