  • On the road two persons, the driver and the verifier, on the equal road should carry out test.

 PERFORMANCE ORDER

  1. Attach scanning tool to the diagnostic socket at the switched-off switch of ignition.
  2. By means of the scanning tool "dump" a code of malfunction (DTC), the current code of malfunction and this framework of freezing which is storing in memory of the electronic control unit.
  3. Start the engine.
  4. Increase speed of the car approximately to 30 km/h (19 miles/h) or more in situation "D" and "2H".
  5. Continue to move with the above-stated speed within 30 seconds.
  6. Stop the car and switch the lever of transfer to situation 4L with the choice lever in situation P.
  7. Increase speed of the car to 25 km/h (15 miles/h) or more in situation D and 4 L.
  8. Continue to move with the above-stated speed within 30 seconds.
  9. Stop the car and check a code of malfunction (DTC) and the current code of malfunction (DTC) by means of the scanning tool.

Instructions of the Table of diagnostics of an automatic transmission are executed?

Pass to a step 2

Pass to the Table of diagnostics of an automatic transmission

2

Check of the bottom switch of a full drive and its electroscheme:

By means of the scanning SUZUKI tool:

At the switched-off switch of ignition attach scanning SUZUKI tool to the diagnostic socket

Turn on the ignition switch.

On the scanning tool choose a mode «List of data»

Check on the display a signal of the bottom switch of a full drive (INCL. or OFF) when switching transfer to each situation

Situation 4Н or 2Н: OFF.

Situation 4L: INCL.

VYKL signal / INCL. is highlighted, how is described above?

Without the aid of the scanning SUZUKI tool:

Uncover the electronic control unit (RSM)

Turn on the ignition switch

Check tension on contact of C 51-1-26 for G16/J20 of the socket of the electronic control unit which is becoming isolated at switching of the lever of transfer to each situation

Situation 4Н or 2Н: 10-14 Volts

Situation 4L: 0-1 Volt

Tension such how it is specified?

Check quality of connection on contact of the electronic control unit if in a step 2 the voltmeter is used

If connection as it should be, problem of intermittence of a chain or faulty electronic control unit. Check on intermittence as it is described in Head the General information in the Section Interrupting or weak connection

Pass to a step 3

3

Check of the bottom switch of a full drive:

Check operation of the bottom switch of a full drive as it is described below in subsection Check of the bottom switch of a full drive

Results of check are satisfactory?

Short circuit or rupture of a chain of "Or/W" or “B”. If wires and sockets as it should be, replace with the serviceable electronic control unit and recheck

Replace the bottom switch of a full drive

Check of the bottom switch of a full drive

 PERFORMANCE ORDER

  1. Disconnect "minus" a battery cable.
  2. Disconnect a hitch of the bottom switch of a full drive.
  3. Check connection between contacts of the bottom switch of a full drive.
  4. There should be a contact when switching the lever of transfer to situation 4L, and a besstupenchatost – when switching the lever of transfer to situation 4H or 2H.
  5. If it is not present, replace the bottom switch of a full drive.
  6. Connect a hitch of the bottom switch of a full drive and "minus" a battery cable.
