The defect
The involved vehicles have "command kits" which automatically set the parking brakes during refuse loading. If power IS lost due to a blown fuse or the ignition switch IS turned off, the parking brakes would be released.
The remedy
The command system control circuit will be modified so that a loss of electrical power for any reason will not cause the parking brakes to be released.
