Outputs of the VIMS ECM and AdvisorOutputs
The ECM sends electrical signals through the outputs. The outputs can create an action or the outputs can provide information to the ECM. The ECM can generate output signals to the system components by using: PWM driver outputs, ON/OFF driver outputs, sinking driver outputs, sensor power supply outputs and data link output. The ECM monitors the circuits of the output components. If the ECM determines that an abnormal condition exists in one of the circuits, the ECM will log a diagnostic code for the involved component.Alarms
Action Alarm
Illustration 2 g00583116
(1) Schematic of Action Alarm (2) Action AlarmThe Action Alarm is activated by the Advisor. The Action Alarm is activated when there is a parameter that is out of the proper range. Also, the Action Alarm is activated whenever there is an active diagnostic fault.Lamps
Action Lamp
Illustration 3 g01476955
The action lamp is a red LED indicator. The action lamp is controlled by the advisor. Illumination of the LED occurs when a condition needs immediate attention. The LED lamp is connected to the following pins on the Advisor: 56 411-PK and 57 J846-BR.Indicator Lamps
Illustration 4 g01476774
The LED indicators are controlled by outputs from the VIMS ECM. The LED indicators are used to inform the operator of low fluid levels in various systems. The LED indicators are "push to test". Refer to table 1 for the wire numbers of the LED indicators.

Illustration 5 g01478142
VIMS Service LampThe service lamp is connected to the output of the VIMS electronic control module (connector J1 contact 58). The service lamp has a "blue lens". The service 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 lamp is turned ON in order to warn the service personnel that the VIMS electronic control module has detected an active event ("data or machine"). A flashing service lamp indicates that the event could be damaging to the machine. If the event becomes inactive, the service lamp is turned OFF. However, the event is stored in the memory of the VIMS electronic control module.Relays
Relay (FORWARD HORN)
Illustration 6 g01475679
When the horn button is depressed, the horn relay is energized via wire 320-OR. The horn relay can also be energized by the VIMS ECM via wire 320-OR. The relay allows flow of power from the unswitched fuse (forward horn) to the: Right Hand Forward Low Tone Horn, Right
