Yes. This from a NASA posting in sci.space.news is about as much
detail as I've seen:

"The undocking and
landing occurred a day later than planned because of a hatch sensor
problem Thursday night. That problem prevented hooks on the Poisk
side of the docking mechanism from opening. Station crew members
installed a series of jumper cables, bypassing the sensor, and the
Poisk module hooks retracted. "
