To do this, he presses the Reset button of the trip meter and at the same time turns the ignition switch to position II or III. As soon as the Test indication appears on the display (after about 5-8 seconds), he releases the button. Now the combined instrument panel starts the selective-check module of testing all indicator devices. If you want to continue the work of the self-diagnosis module, press Reset again. Continue this action until the display gives you a solution to your problem or you yourself terminate the work of the self-diagnosis module by turning the ignition key in the OFF direction.
Unfortunately, the self-test does not always activate, but it is worth a try. Otherwise, contact your Ford dealer, who will initially look at you with distrust, but then check the combined instrument with the FDS2000 tester in the workshop. But as an experienced amateur mechanic, after disappointment, you will act pragmatically and without the FDS2000. The oil pressure indicator light does not light. Turn on the ignition, disconnect the wire on the oil pressure switch and apply it to uninsulated metal (to ground). If the indicator light lights, then the defect is in the oil pressure switch (replace). If the light does not light, then check the wire connected to it, the electrical foil of the combined instrument and the light bulb in turn. In a model with a gasoline engine, you will find the oil pressure switch on the engine block right next to the oil filter flange, in a diesel engine, the switch is at the height of the cylinder head on the left side of the engine.
The fuel level indicator does not work. Either the indicator device or the fuel level sensor in the fuel tank is faulty (the float is jammed). It is possible that the current supply is interrupted or the contact with the ground is insufficient. The fuel level indicator itself allows only limited troubleshooting. In order to check the wires on the fuel tank, it is necessary to carry out a number of preliminary works in the Focus, so we recommend that you contact a workshop with a lift and have this work done there.
The fuel pump power supply connection is located in a hidden and difficult to access location.
The indicator lights do not work. First check whether the corresponding fuse is functioning properly, then the wire connections, the current supply wire and the sensor elements. A multimeter will also be of valuable help here. If you have localized the fault, then replacing most of the sensor elements or indicator lights is not too much of a challenge for an amateur. But it is better to refuse to repair the printed circuit board in the combined instrument panel: entrust this to a Ford workshop.
