07 Odyssey unlock problem

2007 Honda Odyssey. Took unlock from the pass kick panel. For some odd some reason, once I hook up the disarm wire (white in the driver's door) the unlock becomes highly intermittent. I tested it with a ground straight from the battery and it does the same thing. I am pulsing the unlock and disarm simultaneously and the car will rarely unlock. I cannot figure this one out.

This is a known issue in Hondas, since the 2003 Accord. It's a shame that going on five model years now, they're still not bothering to note this in the tech sheets. But it's an easy fix. Program your unit for double-pulse unlock. The disarm wire will only pulse once, but the unlock will pulse a second time, and at that time the doors will unlock.
