Figure 6 2015 - Current VSIM
The microcontroller-based electronic Vehicle System Interface Module (VSIM) (also known as
the Vehicle Systems Integration Module/VSIM or the aftermarket module) contains the electronic
logic circuitry and software that enable many of the aftermarket equipment and systems typically
installed on police or fleet vehicles to communicate with and be integrated with the electronic
control modules and features already installed in the vehicle. The VSIM can communicate with
aftermarket modules or with other electronic modules in the vehicle using the Controller Area
Network (CAN) C data bus.
The VSIM is powered by a fused B(+) circuit and is grounded at all times so that it can operate
regardless of the ignition switch position. The module awakens or sleeps based upon the status
of the CAN C data bus network. The module monitors both active and stored Diagnostic Trouble
Codes (DTC) through On-Board Diagnostics (OBD) and communicates with a diagnostic scan tool
using the CAN C data bus.
The VSIM is located under the LH side of the instrument panel assembly.
