When

C802

is

operated

(connection

between

contacts

2

and

3),

a

voltage

is

applied

to

connection

points

1

of

G257

and

G258

through

fuse

E031,

wire

1201,

contacts

2

-

3

of

C802,

wire

4659.

This

relay

is

energised

and,

as

a

result,

a

connection

is

made

between

contacts

3

and

5.

This

causes

a

voltage

to

be

applied

to

connection

point

1

of

B252

through

fuse

E031,

wire

1201,

contacts

5

-

3

of

relay

G257

and

wire

5053.

The

other

connection

point

2

is

connected

to

earth

through

wire

5054,

contacts

3

-

5

of

relay

G258.

The

recirculation

valve,

driven

by

B252,

will

now

close.

The

V

IC

(D900)

also

receives

a

voltage

signal

on

connection

point

8.

The

V

IC

activates

the

“recirculation”

warning

indicator

on

the

instrument

panel

via

the

I-CAN.
