Identification of malfunctions

Step

Action

Yes

No

1

Verification of the electroscheme of a bulb «Raising transfer is switched off»:

At the switched-off switch of ignition disconnect hitches from the electronic control unit.

By means of a service wire connect contact of the disconnected hitch of the electronic E61-20 control unit (at G16/J20 engines) and "earth"

The bulb «Raising transfer joins is switched off» at the switched-on ignition key?

Bad connection of contact E61-20 (at G16/J20 engines). If everything is normal, replace with the serviceable block of electronic control and recheck

The bulb or faulty conducting of "W/B", “B/W” burned down

Table of diagnostics of malfunctions V-2. Verification of the electroscheme of the indicator «Raising transfer is switched off» (the indicator «Raising transfer is switched off» burns steadily)

Electroconducting scheme

See. The table B-1 in this Section.

Identification of malfunctions

Step

Action

Yes

No

1

Check a condition of the switch of interruption of raising transfer.

Press the button of the switch of interruption of raising transfer (1)

The bulb «Raising transfer is switched off» burns steadily?

Pass to a step 2

System as it should be

2

Check the bulb scheme on short circuit

Switch off the ignition key and disconnect sockets of the electronic control unit

Turn on the ignition key

The bulb «Raising transfer is switched off» burns steadily?

The chain of "W/B" is closed on "earth"

Pass to a step 3

3

Check a chain of the switch of interruption of raising transfer

At the switched-off switch of interruption of raising transfer check resistance between contact E61-33 (at G16/J20 engines) the disconnected socket of the electronic control unit and body grounding

There is a connection?

Pass to a step 4

Check a chain of grounding of the electronic control unit on a gap. If a grounding chain as it should be, replace with the serviceable block of electronic control and recheck

4

Check operation of the switch of interruption of raising transfer

Remove a console box

Disconnect the socket of the switch of interruption of raising transfer

Check connection between switch contacts in each of given below provisions:

The switch is released: There is no connection

The switch is pressed: There is a connection

Result of check the satisfactory?

The chain of "Y/R" is closed on "earth"

Replace the switch of interruption of raising transfer

Drawing [A] for a step 1

1 — (When the ignition key is switched on)
Press the button to turn on the switch of interruption of raising transfer.
Again press the button to switch off the switch of interruption of raising transfer.

Drawing [B] for a step 4

2 — When the socket of the switch of interruption of raising transfer) is disconnected
Hold кнопу pressed to close switch contacts.
Release the button to break off a chain in switch contacts.
