VIMSTM display components (1) Gauge cluster module (2) Speedometer/tachometer module (3) Message center module (4) Alert indicator (5) Data logging indicator (6) Gauges (7) Tachometer (8) Ground speed readout (9) Transmission actual gear readout (10) Message area (11) Universal gauge (12) Gauge warning areaThis service program code causes a self test of the outputs of VIMSTM. VIMS outputs are:
Display modules
Action lamp
Service lamp
Action alarmThis test is also initiated when the key start switch is turned from the OFF to the ON position. The length of time for a self test is approximately 6 seconds.This test will not prevent the operator from cranking and starting the engine. However, allowing the self test to run completely is recommended prior to cranking the engine.Note: The only situation that can cause an internal calibration of the gauges (6) and the tachometer (7) is a Key On self test. The Key On self test is initiated by turning the key start switch from the OFF position to ON position. When the key start switch is turned on, the gauge indicators (6) and the tachometer indicator (7) jump to the mid-scale position. The gauges will then sweep to zero. The gauges will then be ready for the system test to begin.Reference Operation and Maintenance ManualThe following items are indications of the system test.
Alert indicator (4) FLASHES.
Data logging indicator (5) scrolls.
Universal gauge (11) sweeps from zero (left) to full scale (right). The gauge sweeps back to the actual condition of the machine for the selected parameter or the parameter that is associated with an "active event".
Gauge warning area (12) at each end of the universal gauge is turned ON.
Message area (10) illuminates every dot on the readout. When the self test is performed with the key ON, the following items are displayed: the part number of the source software, the part number of the configuration software and the version of configuration hardware.
Tachometer indicator (7) drops to zero from the present engine speed and the indicator sweeps to full scale. After the indicator reaches full scale, the tachometer indicator (7) returns to the present engine speed.
Ground speed readout (8) turns on every segment of the readout. The readout looks like 188.
Transmission gear readout (9) turns on every segment of the readout.
The action lamp illuminates.
The action alarm turns on and off as if a category 3 warning is present.
Gauge indicators (6) drop from the present reading to near zero. The indicators then sweep to full scale. The indicators return to the values that were shown prior to the test.
"MPH" indicator and "KM/H" indicator turn on.
The background mode shows the time of day and the machine hours are shown on the message area if there are no active events. The payload data is shown instead of the background display during the payload cycle.
The payload lamps flash.
The service lamp flashes.The following example is a message center display for an off highway truck.
