Shaft Lock Module - Description

DESCRIPTION

A shaft lock module is part of the premium version of the Sentry Key Immobilizer System (SKIS) in the Vehicle Theft Security System (VTSS). The premium version of the SKIS is only available in vehicles built for certain markets, where the additional features offered by this system are required. The shaft lock module is located in a bracket integral to the lower end of the steering column housing casting below the instrument panel in the passenger compartment. This unit is designed to work in conjunction with the Wireless Ignition Node (WIN) to control a locking bolt that engages a machined slot in the steering shaft to prevent shaft rotation whenever the ignition is in the LOCK position. The shaft lock module can only be unlocked by the presence of a valid FOBIK in the front seat area of the vehicle or in the ignition switch.

Concealed within the module is the electronic circuitry of the module, and a bi-directional electric motor that actuates the locking bolt. The module is connected to the vehicle electrical system through the instrument panel wire harness.

The mounting provisions for the shaft lock module are designed to resist unauthorized tampering. The module cannot be removed from the steering column while the steering column is installed in the vehicle. The shaft lock module cannot be adjusted or repaired and, if ineffective or damaged both the shaft lock module and the WIN must be replaced. Whenever a shaft lock module is replaced the WIN must also be replaced. To remove a locked shaft lock module from a removed steering column Shaft Lock Module - Removal.
