For what it's worth, AutoZone can test ICMs for free.

Bench testing ICMs and coils is virtually useless, however. It does not simulate the heat that often causes these components to fail. I recommend replacing these critical and problematic components every 120,000 miles or 10 years, whichever comes first.
