Auxiliary devices

In quality спецкомплектации below on the right and at the left in the combined device two additional devices – the gauge of temperature of oil and the voltmeter can be established. Check up:


  1. The gauge of temperature of oil: disconnect a wire from the gauge (about assembly position see in following section), put to weight.
  2. If the arrow of the tool does not deviate, defect in a bringing wire, the microprocessor or the device.
  3. Otherwise the reason in the gauge.
  4. The voltmeter: check up pressure on voltmeter sockets at the disassembled combined device (the socket is connected).
  5. If pressure is, but there is no indication the device is faulty.

Assembly position of the gauge of temperature of oil

  • The four-cylinder engine: the Gauge is on a flange of the oil filter at the left on the engine. Colour of a wire: dark blue/white.
  • The six-cylinder engine: the Gauge of temperature of oil is at the left below on the forward party of the engine. Because of its inaccessibility of a wire to the gauge are united in one штекерный I will corrode behind on the left head of the block of cylinders. Colours of wires штекерного connections: black/brown from the gauge of temperature of oil to a socket; dark blue/white from a socket to the combined device. Other wires of a socket: white/grey to the switch of pressure of oil.

The gauge (1) indicators of temperature of oil and the gauge of pressure of oil (2) are in the four-cylinder engine on a flange of the oil filter on an engine left-hand side.
