There are two primary types of Smart Switch Two position switch: Supplies an on or off signal to the BHM Three position switch: allows for an up down off signal to the BHM (Used in applications where more than one input is required.). this is done through the features screen using service link. In order for a smart switch to work on the vehicle the Bulk head module must be trained to hear it. 10 1 2 EPA 2007 Models Low Current Smart Switches Low Current Smart Switch Easily identified by the Black backing on the switch 860-004 SMART SWITCH EXPANSION MODULE (SEM) A Switch Expansion Module (SEM) is available for the Business Class® M2 vehicle when more than five smart switches are installed on the vehicle.

Three common faults can occur with Smart Switches Extra Smart Switch fault indicates that a smart switch has been installed that the vehicle is not programmed to utilize. Missing Smart Switch fault indicates that a smart switch has been programmed but is not installed.Smart switches: Smart switches are low current switches that use signals to communicate with the Bulk Head Module to tell what function they effect and what state they are in (on or off etc.) Smart switches identify themselves by two voltage signals to the bulkhead module. To fix this error the duplicate smart switches must be removed from the system. Optional switches can be ordered in a one-. .
