Under certain conditions, the PV485 digital display can
become inoperable. If the display screen is completely
black, it must be replaced. If the gauges on the screen
become gray (Figure 5-65), the display panel is not
receiving communication over the CANbus. If this
occurs, check the connector. If the gauges are still gray,
check the ECU powering up.
