Checks

TCM

Include ignition, - do not start the engine.

Uncover the contact TCM socket (the driver's party) and check correctness of distribution of tension on its plugs, - measurement is performed between the corresponding plug and weight In case of need replace the module of management.

The ID card of plugs of the TCM socket for diesel models

Electromagnetic valves

On the example of petrol models

 PERFORMANCE ORDER

  1. Disconnect an electrical wiring from TCM and measure resistance between plugs No. No. 8, 7 and 22 of its contact socket, - the required value makes 11 ÷ 15 Ohm at 20 °C.
  2. Giving on plugs No. No. 7, 8 and 22 tension () batteries, aurally make sure of serviceability of operation of electromagnetic valves (clicks have to sound in AT case pallet).

Sensor switch of provisions of the lever of the selector (PNP)

Checks

PNP plays a role of sensors switches of permission of start and activation of fires of a backing.

 PERFORMANCE ORDER

  1. Make sure of serviceability of activation of a starter in provisions "P" and "N" of the selector lever, in other provisions of the lever activation of a starter should not be represented possible.
  2. Make sure of serviceability of activation of fires of a backing at transfer of the lever to situation "R" (ignition has to be included).
  3. Disconnect an electrical wiring from the sensor switch and check correctness of distribution of provodimost between plugs of the contact socket in various provisions of the selector lever. In case of need make the corresponding adjustment.

  1. Connect an ohmmeter to contact plugs of the socket of the sensor.
  1. Observe behind reaction of an ohmmeter on the driving wheel of the car which is torn off from the earth rotation, - the arrow index has to fluctuate within the range of 0 ÷ 41 Ohms. Replace the faulty sensor.

Sensor switch of stoplights

 PERFORMANCE ORDER

  1. Disconnect an electrical wiring from the foot brake of the sensor switch fixed under a pedal.
  1. By means of an ohmmeter check correctness of distribution of provodimost between four plugs of the sensor switch in both provisions of the last. Compare results of measurements to the data provided in the table, - replace the faulty sensor switch.

Sensor switch of activation of the HOLD mode

Disconnect an electrical wiring from the AT selector of the HOLD sensor switch located under the lever.

By means of an ohmmeter check correctness of existence/lack of conductivity between plugs of the 2-contact socket of the sensor switch in both provisions of the last. In the included position of the sensor switch conductivity has to be absent, in switched off - to take place.

Switch of the POWER/ECONO modes

 PERFORMANCE ORDER

  1. Disconnect an electrical wiring from the switch.
  1. By means of an ohmmeter check correctness of distribution of provodimost between four plugs of the contact socket of the switch in both provisions of the last. Compare results of measurements to the data provided in the table, - replace the faulty sensor switch.

1 — the Sensor switch of activation of the light indicator 4WD
2 — the Sensor switch of the lowering transfer (4WD LOW)
3 — VSS
4 — the Transfer case
  1. By means of an ohmmeter check correctness of existence/lack of conductivity between plugs of the 2-contact socket of the sensor switch in both provisions of the last. In the included position of the sensor switch conductivity has to be absent, in switched off - to take place.
