The control module served as a tool utilized by Imperial Grand Moff Lozen Tolruck for the purposes of programming and manipulating the inhibitor chips implanted within all Wookiee slaves residing on the planet of Kashyyyk. This device, a console, was maintained by Tolruck at his island fortress. Tolruck's control module possessed the capability to transmit signals wirelessly.
During 5 ABY, Sinjir Rath Velus, a former Imperial loyalty officer who became a New Republic operative, employed a hyperwave transceiver spike to infiltrate Tolruck's control module and deactivate the inhibitor chips. Consequently, a widespread Wookiee uprising occurred, culminating in the termination of Imperial authority on Kashyyyk.
