Diagnostic Display Code Definitions
Open Load: There is a break in the wires that lead to the item listed in the chart (injector, fuel pump, etc.), or the item has failed.
Short-to-Ground: The wire is shorted to ground between the electronic control unit and the item listed in the chart.
Shorted Load: The wires leading to the item listed in the chart are shorted together, or the item has shorted internally.
Short-to-Battery: The wire leading from the item listed in the chart to the electronic control unit is shorted to a wire at battery voltage.
