5130, 5130B and 5230 Excavators, 784B, 785B, 785C, 789B, 789C, 793B and 793C Off-Highway Truck/Tractors and 992G, 994 and 994D Wheel Loaders Vital Information Management System (VIMS) Caterpillar

This service program code allows the service technician to choose the display mode that controls the service lamp. The service lamp setting can be selected for the entire system. This includes completely turning OFF the service lamp.

Note: This feature is a characteristic of the 9.5X and later class of on board software.

Security

1. This service program code only functions while the service tool (VIMS-PC) is connected.

2. After the service tool (VIMS-PC) is disconnected for 30 seconds, this service program code will no longer be active.

The service technician may choose from any of the five display modes of the service lamp:

1. 1-2 SNAPSHOTS FULL: The possible actions of the service lamp for this mode are listed below after either one or both of the snapshots are stored:

   • The service lamp flashes at ten minutes intervals: “two seconds on and two seconds off”. The sequence repeats ten times when the memory of snapshot No. 1 is full.

   • The service lamp flashes at five minute intervals: “four seconds on and two seconds off”. The sequence repeats ten times when the memory of both snapshots are full.

   • The service lamp is illuminated steadily when any event is present.

   • The service lamp will flash at an interval: “one second on/one second off”. The service lamp will flash when an event that could cause damage to the machine is detected.

2. 2 SNAPSHOTS FULL: The possible actions of the service lamp for this mode are listed below only after the second snapshot is stored:

   • The service lamp flashes at five minute intervals: “four seconds on and two seconds off”. This sequence is repeated ten times. The sequence is then repeated after a five minute pause.

   • The service lamp is illuminated steadily when any event is present.

   • The service lamp will flash: “one second on and one second off”. The service lamp will flash when an event that could cause damage to the machine is detected.

   Note: The operator does not receive a notification in this mode if the memory for snapshot "No. 1" is full.

3. NO SNAPSHOT NOTICE: The possible actions of the service lamp in this mode are listed below:

   • There is no indication of the number of snapshots that are stored in memory.

   • The service lamp is illuminated steadily when an event is present.

   • The service lamp will flash at an interval: “one second on and one second off”. The service lamp will flash when an event that could cause damage to the machine is detected.

   Note: The operator does not receive a notification in this mode if the memory for either snapshot is full.

4. DAMAGE EVENTS ONLY: The possible actions of the service lamp for this mode are listed below:

   • The service lamp will flash at an interval: “one second on and one second off”. The service lamp will flash when any event that could cause damage to the machine is detected.

   • There is no indication regarding other events.

   Note: The operator does not receive a notification in this mode if the memory for either snapshot is full.

5. "NEVER ON": The service lamp is disabled in this mode for all cases. The service lamp will never illuminate.

   Note: “Snapshot” is a new term that has replaced “Event Recorder”. Snapshot data that is collected by the on board system is viewed with VIMS-PC. Files with “.evr, ev1, ev2, etc.” extensions are the snapshot files. VIMS-PC uses these files in order to display snapshot data.

Procedure

Note: This service program code is in a “view only mode” when VIMS-PC is not connected.

1. Connect the service tool (“VIMS-PC”) to the RS-232 connector. The message center should be in the background mode. The following items should be displayed on the message center: time, date and service hours. Enter the SVCSET (782738) command via the keypad. The message center will show:

   Note: The display first shows the present setting. The default setting is displayed on the message center when a new source has been loaded or a new configuration has been loaded. The previous example reflects the default setting of "1.1-2 SNAPSHOT FULL".

2. The arrow keys are used to move through the list of available settings. The "OK" key selects the desired setting.

   Note: If the right arrow key is pressed again the list remains at the last setting. Press the left arrow key in order to move back through the settings.

3. Press the "OK" key in order to accept the setting when the desired "Service Lamp Setting" is displayed on the message center. The option that was selected is now the new service lamp mode.

Note: The setting of the service lamp is set to option 4. The title of option 4 is "DAMAGE EVENTS ONLY". This setting will be used for all operations until one of the following events occur:

• New source software is loaded.

• New configuration software is loaded.

• The backup battery is replaced while the disconnect switch is in the OFF position.

• The user selects a new setting with VIMS-PC. The service tool (VIMS-PC) must be connected to the machine.

The following table summarizes the service lamp behavior in the five lamp setting modes.
