Vacuum Fluorescent Display (VFD)

The Vacuum Fluorescent Display (VFD) module is soldered to the EMIC electronic circuit board. The display is active when either door is opened or with the ignition switch in the ON or START positions, and inactive about 20 seconds after both doors are closed when the ignition switch is in any other position. If a door is left open with ignition switch is in any position except ON or START, the VFD will remain illuminated until the interior lights control battery saver timer expires after about 20 minutes. The VFD has several display capabilities including: odometer, software version display, trip odometer, and can display various diagnostic information. An odometer/trip odometer switch on the EMIC circuit board is used to control several of the display modes. This switch is actuated manually by depressing the odometer/trip odometer switch on the knob that extend through the lower edge of the cluster lens, just right of center. Actuating this switch momentarily with the VFD illuminated will toggle the display between the odometer and trip odometer modes. Depressing the switch button for about 2 seconds while the VFD is in the trip odometer mode will reset the trip odometer value to zero. Holding this switch depressed while turning the ignition switch from the OFF position to the ON position will activate the EMIC self-diagnostic actuator test. When illuminated, the VFD will automatically display the message NO BUS in place of the odometer or trip odometer information if there is a loss of PCI data bus communication, and will display the message NO FUSE if the instrument panel is not receiving battery current through the fused B+ circuit from the IOD fuse. The VFD will also display various information used in several diagnostic procedures.
