VEHICLE INTERFACE MODULE (Figure 1–9)
The vehicle interface module (VIM) provides relays, fuses, and connection points for interface with the output side
of the vehicle electrical system. VIMs are available for both 12V and 24V electrical systems. The VIM for 12V
systems uses all 12V relays. The VIM for 24V systems has all 24V relays. Refer to the Parts Catalog for the
transmission assembly number that you are servicing for detailed parts information. Refer to Pages D–23 and D–24
for VIM wire number and terminal information.
Some OEMs may provide their own equivalent for the VIM which performs the same functions as the VIM shown
in Figure 1–9.
