5.2.9. Removal and installation of sensors of To/in system

Observe all necessary precautionary measures connected with service of To/in systems (see. Section 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 chamber of an air path with a catchment basin (see. Head of the Power supply system and production of the fulfilled gases).
  3. Having turned under 45 ° in specified in drawing an arrow the direction, remove the sensor of humidity of air (B31/2) and disconnect from it electroconducting.
  4. Installation is made upside-down, - track, that electroconducting of the sensor did not get under an evaporator casing.

Sensor of temperature and pressure of a coolant

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

 PERFORMANCE ORDER

  1. Need for replacement of this sensor arises at development of leakages of a coolant, and also at the To/in system exit out of operation.

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

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

The receiver dehumidifier is subject to replacement without fail each time opening of a working contour of To/in system, - do not forget to consider when refueling system receiver volume (see. Specifications)!

  1. Release bandage tapes (4) and shift aside hoses of an okhladitelny path.
  2. Disconnect electroconducting (2) from the sensor of temperature and pressure of a coolant (B12/2).
  3. Keeping from a provorachivaniye the pressure head line (3), turn on 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 carving connections by compressor oil.
  5. In summary check serviceability of functioning of К/В system.

Sensor of temperature of the evaporator

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 a service mode of system of an emergency call of TELE AID (see. Section Activation/deactivation of a 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 — battery Grounding
  1. Uncover at the left under the dashboard (see. Head Body).
  2. Having pulled in specified in a picture an arrow the direction, take the temperature sensor (B10/6) from an evaporator casing, then disconnect from it electroconducting.
  3. Installation is made upside-down.
  4. In summary деактивируйте a service mode of TELE AID system (see. The section Activation/deactivation of a service mode of system of an emergency call of TELE AID) also make cleaning of memory of the module of onboard self-diagnostics (see. Head of System of electric equipment of the engine).
