PV480 Troubleshooting
Under certain conditions, the PV480 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 5-53), 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.

Check PV480 Connector
1. Ensure the ignition switch is in the OFF position
before starting the machine.
2. Remove the main connector from the rear of the
PV480 digital display controller.
3. Inspect the terminals in positions 14 (green) and 26
(yellow) for the CANbus communication.
4. If terminals are properly seated, carefully “unlock”
the red retaining clip and slide away from the wires.

connector shell.

position and ensure terminals are ush with the red

7. Reinstall connector on to the PV480 panel, making
sure the connector shell locks into its mate on the
display panel.
