Multiplexing technology allows manufacturers to reduce cost while increasing flexibility in design and improving diagnostic capability. Vansco's VMM System provides a "total systems solution." 1. Economical and Rugged VMMs were designed and built for the highway and off-highway industry by experienced professionals. This system is compliant to SAE J1455 and J1113 Environmental Standards. 2.

Single Part Number System reduces inventory costs and simplifies diagnostic and repair work. 4. "Plug and Play" Modules allow users to install a new module without having to resort to laptop computers or other external devices. Very little training is required to diagnose and replace a module. 5. Improved Connectivity with other parts of the electrical system on the vehicle. The VMM System uses industry standard SAE J1939 CAN-based architecture for easy connectivity to other standard devices. 6. Simple Diagnostics With indicator lights on each module and intuitive diagnostic software in your PC, the VMM System reduces the time required to find and repair system faults, thereby reducing downtime.
