Additional devices

If additional devices are established, instead of the switch with a hydraulic actuator 0,3 bar costs the sensor of pressure of oil (3). To it are connected a wire of a food (2) and a switch wire with a hydraulic actuator (1).

As additional equipment in the central console three additional devices – an oil manometer, the sensor of temperature of oil and the voltmeter can be built in. For their removal it is necessary to remove previously the middle console (see the section Salon).

PERFORMANCE ORDER

Check of the sensor of pressure of oil, sensor of temperature of oil: to disconnect a wire from the corresponding sensor (the provision of installation see the following section) and to bring to "weight":
If the arrow of the device does not deviate, means, are faulty either conducting, or the device.
Otherwise a cause of defect – the sensor.
Voltmeter check: to check tension on voltmeter contacts.
A food is present, but is not displayed: the voltmeter is faulty.

Provision of installation of the sensor of pressure of oil, sensor of temperature of oil

Models with the 4-cylinder engine: both sensors are located on a flange of the oil filter at the left at the engine.
Models with the 5-cylinder engine: the sensor of pressure is located on the left side of the motor block, the sensor of temperature of oil is on the right ahead below on the engine. It is screwed in there instead of a carving stopper for a safety valve of the oil pump. Be careful at a vyvinchivaniye: the stopper is under a spring tension. The provision of a spring and klapanny plunzher is extremely important!
Models with the 6-cylinder engine: the sensor of pressure of oil is on the left side of the motor block ahead below, the sensor of temperature of oil is located at the left below on the face party of the engine. Because of bad availability of a wire to sensors are collected in plug connection behind at the left head of the block of cylinders. Colors of cables in plug connection: green-black to the sensor of temperature of oil; dark blue-white to the sensor of pressure of oil; white-gray to the switch with a hydraulic actuator 2,5 bar; dark blue-black to the switch with a hydraulic actuator 0,3 bar.
