When

the

P

switch

(C750)

is

operated,

a

voltage

is

applied

to

connection

point

D27

of

D900

(VIC)

through

fuse

E091,

wire

1240,

contacts

5-1

of

switch

C

750

and

wire

4594.

The

P

TO

can

also

be

switched

on

through

connection

point

11

of

A068

(engine

speed

control

application

connector).

This

means

that

a

“request”

to

use

the

PT

O

has

been

made. This

“request”

is

implemented

depending

on

the

conditions

programmed

in

the

VIC.

A

condition

might

be

that

the

parking

brake

m

ust

be

engaged.

In

this

case,

a

voltage

is

applied

to

connection

point

1

of

parking

brake

switch

F000

through

fuse

E035,

If

If

the

the

takes

place:

A

voltage

is

applied

from

connection

point

B23

of

D

900

through

wire

4596

to

connection

point

1

of

B

245,

thereby

switching

on

the

PT

O.

The

V

IC

checks

whether

the

P

TO

is

actually

switched

on.

This

takes

place

as

follows:

When

the

P

has

been

switched

on,

F087

is

operated

of

F

VIC

then

sends

a

the

D

IP

and

the

“PT

is

activated.

If

the

P

does

NOT

switch

on,

F087

is

NOT

operated

and

connection

point

B14

of

the

VIC

is

NOT

connected

to

earth.

A

fter

a

period

of

is

sent
