Switch Monitor Test
PURPOSEThe 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.
