Operating Instructions - Section 32 OM3217 Page 32-24 Interface Module The interface module (3, Figure 32-12) receives data from the sensors installed on the truck and sends this information to the VHMS controller. There is a small green LED light (2) on the face of the controller. With the key switch ON, the light should be blinking. If the light is continuously illuminated, there is a problem in the controller. When a new interface module controller is installed on the truck, new software has to be installed inside the controller. The IM-Diag connector (4) is used to con- nect the interface module to a personal computer for installing software.
