Optional equipment
Removing and installing flasher Neutral breaker used in the indicators and hazard warning lights located on the bracket to the left of the steering column. Disconnect the negative battery terminal. Remove the trim at the bottom of the dashboard on the driver side.

Disconnect the connector and remove the bracket breaker (Fig. 13.60). Installation is performed in reverse order of removal.
Checking fuel level sensors and coolant temperature If the fuel gauge and coolant temperature give incorrect readings, malfunctions may be a pointer, sensor or wires. Identify the problem, you can use a multimeter and a few resistors. The fuel gauge Access to the fuel level sensor after removing the rear seat and the housing. Disconnect the connector from the fuel level sensor.

Connect the resistor 8 to 96 ohms between contact ?�Y?� connector and the "weight" of the car (Fig. 13.61). Make sure the wires do not touch the "weight" of the car, and switch on the ignition.

Wait 2 minutes to stabilize readings pointer, then guided Fig. 13.62 or 13.63, compare the actual reading of the expected values. If possible, repeat the test with the resistors other resistance within the specified limits. Before changing the resistor switch off the ignition. If the pointer indicates full or empty the tank, regardless of the resistor means in the wires of the sensor circuit or open circuit. Otherwise false readings caused by the malfunction of the fuel gauge.
A WARNING Gasoline is extremely flammable, when working with elements of the power system is forbidden the use of fire, sparking devices open by fire-dangerous light fixtures and smoking. Avoid creating sparks when working with cables and electrical devices. |
Fuel Level Sensor

| Fig. 13.65. The resistance of the fuel level sensor depending on the position of the float: a - empty tank (installation height of the float 12 mm, the resistance 110 ohms); b - the tank is half full (float installation height 69 mm, the resistance of 32.5 ohms); with - a full tank (float mounting height 128 mm, Resistance 3 Ohms)
|
Connect multimeter to measure the resistance to the pins of the fuel level sensor. By moving the float up and down, compare measured at various points with the required resistance values (Fig. 13.65). If the value of resistance is not as specified, replace the fuel level sensor. Coolant temperature Disconnect the connector from the temperature sensor located in the rear of the thermostat housing. Connect the resistor of 12 to 230 ohms between pin connector and the "weight" of the car.

Make sure the wires do not touch the "weight" of the car, and switch on the ignition. Wait 2 minutes to stabilize readings pointer, then guided Fig. 13.66, 13.67, 13.68, compare the actual with the expected testimony of a pointer. If possible, repeat the test with the resistors other resistance within the specified limits. Before replacing the resistor switch off the ignition. If the temperature gauge indicates the maximum or minimum temperature, regardless of the resistor in the wiring of the sensor circuit or open circuit. Otherwise false readings caused by the malfunction of the coolant temperature gauge. Coolant temperature Drain the coolant to a level below the sensor and remove it. Hang sensor on a string in a glass vessel filled with water, and connect the ohmmeter leads to the terminal connector and the sensor body. Monitor the temperature of the water with a thermometer. Heat the water to 80 ?� C, the sensor resistance must be between (53,5 ?� 4,2) ohms. If the sensor resistance is not correct, replace the sensor. Place the sensor in place and fill in cooling liquid in cooling system.
Relay Replacement
| Fig. 13.69. Location switch in the car: 1 - the relay of headlights; 2 - the ignition relay; 3 - the radiator fan relay; 4 - the relay central locking; 5 - horn relay; 6 - control relay switching brake light / tail light; 7 - heater relay; 8 - the relay wiper intervals; 9 - timer lighting door lock; 10 - the relay of a sound signal; 11 - flasher; 12 - C relay
|
The number and function of the relay set vary depending on the model and the vehicle equipment. The standard arrangement of the relay shown in Fig. 13.69. If the electrical circuit, which has a relay fault is detected, do not forget that it can be the cause of damage to the relay. Check whether this is by installing a new serviceable relay. To replace the relay, remove the retaining clips and remove the screws, and then remove it from the connector. Installation is performed in reverse order of removal.
The system of illumination of the castle On vehicles equipped with lighting system lock, driver's door lock and ignition lit for about 20 seconds after lifting the door handle. In addition to illumination, this system includes elements such as the timer set on the bracket near the steering column, and the switch on the door handle.

|
To access the backlight lamp and door lock switch on the door handle must remove the door trim. To replace the switch is necessary to remove the outside door handle (Fig. 13.70).
