Service indicator Lamp (1) Service indicator Lamp (2) SchematicThe service indicator lamp is connected to the service lamp output of the VIMS electronic control module (connector J1 contact 58). The service indicator lamp has a blue lens. The service indicator lamp is located outside the cab in an area that is easily seen by someone that is a distance away from the machine. The service indicator lamp is turned ON in order to warn the service personnel that the VIMS electronic control module has detected an active event. A flashing service indicator lamp indicates that the event could be damaging to the machine. If the event becomes inactive, the service indicator lamp is turned OFF. However, the event is stored in the memory of the VIMS electronic control module.The memory in the main module is checked for any inactive events when the key start switch is turned to the ON position. If any events are found, the service indicator lamp is FLASHED three times. If no events are found, the service indicator lamp is FLASHED once. The service indicator lamp can be reset via the keypad or the off-board service tool even if the event is still active. For more information, see the Systems Operation, "Service Operations" section of this manual.
