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 the144-7172 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.

Main Module
SMCS Code:7601-EK2; 7610 g00568328 Illustration 157 g00568367 Illustration 158Limited Mode/Application Mode (V3.0 Hardware)
The VIMS main module operates in one of two modes:
•
limited•
applicationThe VIMS operates in the LIMITED MODE when no source software and/or configuration software is installed in the VIMS main module. VIMS functionality is limited until the installation of all necessary software. Any error messages in this mode come from a list that is contained in the main module (ROM) regardless of software. The main module is programmed to recognize internal problems before installing the software. The main module generates the error messages in order to aid the service technician in troubleshooting problems with the software installation process. APPLICATION MODE is operation of the main module after installing the source software and configuration software. APPLICATION MODE is the normal VIMS operating mode which follows the self test after the key start switch is turned to the ON position.
Machine Information Stored in the Main Module (V3.0)
The version 3.0 main module stores the following basic machine information in a semi-permanent (EEPROM) type of memory. The semi-permanent (EEPROM) memory is unchanged by flashing the CONFIGURATION software with the exceptions that are noted in Table 14. The configuration software will allow some keypad commands and the service tool to change this information.

The VIMS main module monitors the status of the machine systems continuously. The main module makes decisions based upon the input from the following components:
•
VIMS interface modules•
VIMS keypad module•
Other electronic control modules•
Internal calculationsThe main module sends information to VIMS interface modules and other electronic control modules on the machine. The input and output of this information takes place over the CAT data link. The outputs of the main module notify the operator and the service technician of the status of the machine systems. The VIMS machine system information is shown on the display modules that are listed here:
•
Quad gauge module•
Speedometer/tachometer module•
Message center module•
Action lamp•
Action alarm•
Service lampThe service indicator lamp is used by the service technician and on-site maintenance personnel. The service indicator lamp is not visible from the cab. The main module uses two RS-232 data link outputs to communicate data to off-board systems. A 37 contact connector is located on the VIMS main module. The connector is used to connect the necessary harness wiring to all the system components. The module identifier (MID) for the VIMS main module is listed here:
49 –VIMS Main Module
Input/Output
CAT Data Link
The connector contacts of the CAT data link 4, 5, 6, and 7 on the VIMS main module, provide a communication link with the other electronic control modules on the machine. The CAT data link is bidirectional. This bidirectional functionality allows the input/output of data between electronic control modules. The CAT data link permits the sharing of information such as engine oil pressure, machine codes and diagnostics. The VIMS main module can communicate with two identical CAT data links. The two data links are identified as the right or the left CAT data link. The identical data links work independently of each other. This connects the main module in a loop with the other VIMS modules. The loop allows the VIMS modules two possible paths of communication. Two communication paths allow the VIMS modules to communicate even if the loop is broken by harness failures.
RS-232 Data Link
The connector contacts of the VIMS main module (16, 17, 18 and 19) provide two RS-232 serial ports. The two serial ports allow the VIMS main module to communicate with the off-board systems. The RS-232 data links are bidirectional. The bidirectional function allows the main module to input/output information. One port is used to communicate with an off-board service tool. The second port is used in order to broadcast data to off-board systems, as required.
Display Data Link
The VIMS main module contacts 26, 27, 28 and 37 provide a serial port for the Display Data Link. The main module uses the display data link to communicate with the display modules. Power for these modules (connector contact 25) is 9 Volts relative to ground (connector 37). The 6-contact connectors in the machine harness for any of the display modules can be interchanged with any other display module. This is especially helpful for troubleshooting.
Keypad Data Link
The keypad data link (connector contact 29 and 37) is used to provide a serial port for communicating keypad data to the VIMS main module.
Inputs
Switch Input - Key Start Switch
The input from the key start switch (connector contact 8) provides information about the status of the key start switch (ON or OFF). The input signal from the key start switch is used to turn on the main module. When the key start switch is in the ON position, this input is connected to +battery. When the key start switch is in the OFF position, the input is open (floating).
Sensing Input - System Voltage
The sensing input for system voltage (connector contact 1) tells the main module the voltage of the machine electrical system. harness wiring connects the VIMS circuit breaker to this input (connector contact 1). This voltage information helps determine the condition of the electrical system. This input is also the +battery supply for the VIMS main module. This input provides power to the battery backed up memory in the event of a failure to the internal backup battery (3 volt) or the internal backup battery is removed.
Sensing Input - Lighting
The sensing input for lighting (connector contact 9) tells the main module when the machine panel dash lamps are ON. Harness wiring connects the panel lamp circuits to the sensing input for lighting. The sensing input for lighting is used to determine when the back lighting of the message center module should be dimmed in V2.0 hardware. The V3.0 hardware allows the operator to control backlighting through the keypad. 9.X class of on board software is required to adjust backlighting through the keypad. Refer to the Systems Operation, “Service Operations” section of this manual for additional information.
Keypad Input
The keypad input (connector contact 29) receives information from the keypad.
Outputs
Service Lamp
When a VIMS event is detected, the main module activates the service lamp output (connector contact 21) and the service lamp is turned ON. The service lamp remains ON whenever the event is active. If an event could be damaging to the machine, the service lamp is FLASHED. The service lamp can be turned OFF with the keypad. Events are not cleared from the main module memory when the service lamp is turned OFF. If the event becomes inactive, the service lamp is turned OFF. When power is applied to the Vital Information Management System, the main module memory is checked for any inactive events that have not been cleared. If any inactive events are found, the service lamp is FLASHED three times. If no events are found, the service lamp is FLASHED once as a lamp test during the VIMS self test.
If an event is acknowledged via the keypad, the service lamp will not turn OFF. Refer to the Systems Operation, “Service Operations” section of this manual for additional information on turning off the service lamp with the service program code “SVCLIT”.
Action Lamp
The action lamp output of the main module (connector contact 20) is activated when a category 2 or 3 warning is present and this will cause the action lamp to FLASH. For more information, see the Systems Operation, “Warning Operation” section. Action Alarm
The action alarm output of the main module (connector contact 24) is activated when a critical abnormal condition category 3 is present and this will cause the action alarm to SOUND. For more information, see the Systems Operation, “Warning Operation” section.
Display Power Supply
The display power output of the main module (connector contact 25) provides 9 volts DC power to the following display modules:the quad gauge module, the message center module , and the speedometer/tachometer module. The other display outputs of the main module connector contacts 26 through 28 provide the information that is shown on the display modules via the Display Data Link. These outputs are connected to all display modules. VIMS Internal Battery

VIMS Internal Memory Backup Battery
A long life three volt lithium battery is contained in the VIMS main module. The battery allows the memory of the main module to hold data when power is removed from the main module (OPEN disconnect switch). The time/date functions are also powered by the battery.
All on board stored data in V3.0 hardware (not source or configuration software) is retained in battery-backed memory (volatile). This type of memory will lose data if power is removed. When the disconnect switch is in the ON position, the machine electrical system will power the main module. This allows the stored data to be retained. The backup battery takes over when the disconnect switch is open. The backup battery retains only the stored data.
The backup battery also powers the date/time function in the main module when the key start switch is in the OFF position. This is true whether the disconnect switch is ON or OFF.
For machines in service, the backup battery is expected to have a life of approximately two years V2.0 hardware and the V3.0 hardware has an expected life of approximately 5 years. Refer to the following table for the recommended battery replacement interval.
Table 16
Internal Battery Replacement Hardware
Version
Recommended Battery Replacement
V2.0 Every two years(1) V3.0 Every five years(2)
(1) Battery replacement should be performed annually in climates
with ambient temperatures in the range of 0 to−40C (32 to−40F).
(2) Battery replacement should be performed at a 2 to 3 year
interval in climates with ambient temperatures of 0 to−40C (32 to−40F).
The failure of the backup battery causes an operator warning and a resulting diagnostic code to be stored in the event list.After the event for the failure of the battery, if the key start switch is put in the OFF position and the disconnect switch is OPEN, loss of the stored data can occur within several hours or less. When this warning occurs, download the stored data immediately. Then replace the backup battery. DO NOT turn the key start switch to the OFF position. DO NOT turn the disconnect switch to the OFF position.
The reason that the potential loss of data is so sudden after the initial operator warning is due to the discharge characteristics of the lithium battery. The lithium battery holds a constant voltage throughout the life of the battery. Then due to the chemical breakdown (maturing) of the battery, the battery dies very quickly. This is in contrast to the discharge characteristics of the average flashlight battery. The flashlight battery discharges slowly over time, until the battery is dead.
Note:When the9X-5402 Battery is being replaced, ensure that the insulating sleeve is removed from the battery (if present). See the Testing and Adjusting, “Battery Replace” section of this manual for more information.
Note:The 9X-5402 Battery is used in V2.0 main modules (3E-3666 Electronic Control, 115-0648 Electronic Control, 118-9636 Electronic Control and124-6134 VIMS Electronic Control Group). The 101-1785 Battery is used in V3.0 main modules (130-5131 VIDS/VIMS Electronic Control Group 165-8682 VIDS/VIMS Electronic Control Group).

Inputs/Outputs
CAT Data Link
The connector contacts of the CAT data link 21, 22, 23, and 24 provide a communication link with the other electronic control modules on the machine. The CAT data link is bidirectional. The bidirectional functionality allows the input/output of data between electronic control modules. The CAT data link permits the sharing of information such as engine oil pressure, machine codes and diagnostics. The interface module contains two identical CAT data links. The identical data links work independently of each other. The two data links are identified as the right or the left CAT data link. The interface module is connected in a loop with the VIMS main module. The loop provides two paths of communication for the VIMS modules. Two communication paths allow the VIMS modules to communicate even if the loop is broken by harness failures.
Inputs
The inputs describe the status of the machine systems. Switch inputs and sensor inputs are used by the interface module. Switches and harness wiring provide an open or ground to the switch inputs of the interface module. Sensors (frequency or PWM) and harness wiring provide a changing signal to the sensor inputs of the interface module. Switch Input (+24 DCV)
The +24 DCV switch input (connector contact 32) monitors a +24 DCV circuit. The switch input will be
