A temp sensor and an oil pressure sensor along with the needed hardware and harness to install them are an optional accessory package
ENGINE CODE READOUT
As with the stock gauge, the
FUEL GAUGE
This gauge has two fuel gauge displays. The primary display is a bar graph along the bottom of the gauge. This displays the fuel level relatively between empty and full. The second is a percentage of full reading accessed in the message center using the switch. At a reading of approximately %10 the fuel bar will begin to flash as a warning. Also the percent full reading will be displayed in the message center. Pressing the switch will allow the message center to return to other displays. The fuel bar will continue to flash until fuel is added. For some applications, there is no fuel sender and so there is no fuel gauge data available. For these applications, the fuel gauge display can be disabled using the “ FUEL” option in setup.
DIAG MENU
Some diagnostic options are available in the setup routine to allow checking certain inputs to the gauge. The “” option will display the resistance in ohms seen at the gear sender input. This can be used to troubleshoot problems with the gear sender. The “ ” option provides a readout of the current flowing in the 4x4 coil in amps. This can be used to troubleshoot problems with the 4x4 coil wiring and dashboard switch. Refer to the vehicle’s service manual for troubleshooting guidance.
