Shaft Lock Module - Description

DESCRIPTION





A shaft lock module (1) 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. This unit is designed to work in conjunction with the Radio frequency Hub (RF-Hub), to control a locking bolt (2) that engages a machined slot in the steering shaft to prevent shaft rotation whenever the ignition is in the LOCK position. It can only be unlocked by the presence of a valid FOBIK in the vehicle and the Keyless Ignition Node (KIN) in the RUN/START position.

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 and the headliner 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, must be replaced. Whenever a shaft lock module is replaced the Radio Frequency Hub must also be replaced.
