Takes a minute........I do it often to check secondaries. First I make sure the vacuum pump cycles for a few seconds with the key on and then the vacuum pump turns off for a minute or so. This assures there is vacuum to the secondary canisters for proper operation. You need a couple of those test wires with alligator clips on both ends you can pick up at any Radio Shack. Attach one end to Pin C17 as described and the other end to any frame or engine screw/bolt you can find. As you touch the ground wire you will see the secondary canister levers move as described above.

It is fun....try it

This is a quick test anytime you think your secondaries are not working.
