Function test of the circuit breaker

Sometimes even a defective switch can «to confuse» electricity. In the Mondeo, however, «in honor» various types of switches. Their check is best done with a test lamp. Naturally, the needle contact at the end of the lamp must be for this «sharp as a needle», and not overly stupid. If necessary, replace defective switches with genuine Ford parts only.

PROCEDURE

Obtain the appropriate wiring diagram for your Mondeo. First take care of the wires that are under current. To do this, take a test lamp and pierce the wire insulation with needle contacts. Check if voltage is applied to the switch. To do this, it is usually necessary to first turn on the ignition or lighting. The switch is checked as follows: it turns out «releases» whether the switch has its input voltage on the output (output voltage).

Combined instrument

The combined instrument panel of your Mondeo is a single unit in which no element can be replaced separately. It contains indicators and control lamps of all vehicle systems. Since, as practice has shown, lighting in modern salons «live» Long enough, we won't go into any more detail on lighting devices in this chapter. Salon Mondeo is offered in three different versions: Ambiente, Trend and Ghia.



The equipment of the car is largely represented by the work of indicators - therefore, the indicators themselves are visually different, while without any independent functioning. Sensor output signals provide information to indication and alarm systems - you take it into account when you want to unravel the causes of malfunctions in systems.

An electronic speedometer, for example, receives its signal from a speed sensor (VSS), which is located in the gearbox. Other systems that also need this signal are, for example, the engine control unit, ABS / ESP system, speed control system, on-board computer.

Attention - always check the interconnected systems for functioning

Always check interconnected systems, this will lead you to the desired goal faster. All devices and control lamps receive their impulses not through wires, but through a board with applied conductive tracks. Depending on the equipment and model, the boards are different. Therefore, when carrying out repairs and purchasing spare parts, pay attention to this.

Your Ford dealer will immediately recognize the required fee by the code designation in your technical documentation or vehicle passport. However, when troubleshooting, new boards are rarely required: most often only the lamps are defective, or the connector has suffered from poor contact. Therefore, without dismantling the combined instrument, of course, one cannot do here.
