5.2.9. Removal and installation of sensors of the K/V system

Observe all necessary precautionary measures connected with service of the K/V systems (see the Section the General information and security measures)!

Sensor of humidity of air

Details of installation of the sensor of humidity of air (B31/2)


 PERFORMANCE ORDER

  1. Open a cowl.
  2. Remove the rezonatorny camera of an air path with a catchment basin (see the Head of the Power supply system and production of the fulfilled gases).
  3. Having turned under 45 ° in the direction specified in the drawing by an arrow, remove the sensor of humidity of air (B31/2) and disconnect from it an electrical wiring.
  4. Installation is made upside-down, - track that the electrical wiring of the sensor did not get under an evaporator casing.

Sensor of temperature and pressure of coolant

Details of installation of the sensor of temperature and pressure of coolant

 PERFORMANCE ORDER

  1. Need for replacement of this sensor arises at development of leak of coolant, and also at an exit of the K/V system out of operation.

During performance of replacement of the sensor do not allow hit of moisture in a working contour of system!

  1. Open a cowl.
  2. Remove a receiver dehumidifier (1) (see the Section Removal and installation of a receiver dehumidifier), - at once to a zakuporta the open ends of refrigerator lines suitable caps.

The receiver dehumidifier is subject to replacement without fail every time opening of a working contour of the K/V system, - do not forget to consider when refueling system receiver volume (see Specifications)!

  1. Release bandage tapes (4) and shift hoses of a cooling path aside.
  2. Disconnect an electrical wiring (2) from the sensor of temperature and pressure of coolant (B12/2).
  3. Keeping the pressure head line (3) from a provorachivaniye, turn off and remove the sensor (B12/2).
  4. Installation is made upside-down, - do not forget to replace sealing rings, before installation greasing them together with threaded connections compressor oil.
  5. In conclusion check serviceability of functioning of the К/В system.

Evaporator temperature sensor

Details of installation of the sensor of temperature of the evaporator (B10/6)

 PERFORMANCE ORDER

  1. On models of the corresponding complete set (ET2 code) activate the service mode of system of an emergency call of TELE AID (see the Section Activation/deactivation of the Service Mode of System of an Emergency Call of TELE AID).
  1. Include auxiliary and connect it to the regular battery, then disconnect a negative wire from the battery.

    7 — the Auxiliary accumulator
    8 — the Plug of a positive wire of the module
    9 — the Plug of a negative wire of the module
    W10 — Grounding of the battery
  1. Uncover under the dashboard at the left (see the Head Kuzov).
  2. Having pulled in the direction specified in a picture by an arrow, take the temperature sensor (B10/6) from an evaporator casing, then disconnect from it an electrical wiring.
  3. Installation is made upside-down.
  4. In conclusion deactivate the service mode of the TELE AID system (see the Section Activation/deactivation of the Service Mode of System of an Emergency Call of TELE AID) and make cleaning of memory of the module of onboard self-diagnostics (see the Head Sistemy of electric equipment of the engine).
