Component Descriptions

Usage:

793B 1HL
The Vital Information Management System (VIMS) operates on a variety of different machines. Some of the following electrical components may not be installed on every machine. Configuration software provides the VIMS main module with the following information: type of machine and installed onboard components. Refer to the Electrical System Schematic in the machine Service Manual for component locations. The Electrical System Schematic may be used to verify the components that are used by VIMS.

Hardware

This manual describes the version 2.0 and version 3.0 of VIMS hardware. The version 2.0 hardware relates to the original VIMS modules (main module and interface modules) that went into production in the third quarter1994. In the third quarter of 1996, version 3.0 hardware began production. The version 2.0 Interface modules and version 3.0 interface modules have the same physical appearance. Part numbers are the only way to tell the difference. The backup battery holder for the V2.0 main modules are located on the side of the module. In order to access the battery, a black “knob” needs to be unscrewed. V3.0 main modules have an “egg shaped” cover on the top of the module. In order to gain access to the battery, two screws must be removed. This battery is flat with four pin-type contacts on the bottom. An L-shaped tool is required to pry the battery out.

All modules can be mixed and matched with the exception of the 144-7172 VIMS Interface Module. The 9.X or later class of onboard software must be used with version 3.0 modules to gain all benefits and features. The new interface modules should not be mixed with the former interface modules on machines that use 9.X or later class of onboard configuration software. If an 144-7172 VIMS Interface Module is replaced by a older version of interface module, the interface module will function. However, this interface module could also cause the diagnostic type of maintenance events to be incorrectly displayed by using old diagnostic codes or incorrect diagnostic codes.
