If

the

door

unlocking

button

on

the

remote

control

unit

is

pressed,

the

remote

control

unit

will

send

a

fixed-code

signal

to

the

CDS

electronic

unit

(D905).

W

hen

the

CDS

electronic

unit

(D905)

recognises

the

remote

unit

on

the

basis

of

the

fixed

code,

the

remote

unit

w

ill

send

coded

messages

to

the

unit

(D905).

T

hese

m

essages

are

coded

with

a

rolling

code.

This

rolling

code

will

change

every

time

the

remote

control

is

operated.

After

the

CDS

electronic

unit

(D905)

has

accepted

the

m

The

CDS

unit

(D905)

checks

the

status

of

the

output

to

the

m

(B199).

T

his

is

done

to

ensure

that

the

D

L

is

not

connected

to

earth

when

the

m

otor

is

in

the

“open”

position.

The

CDS

unit

can

deduce

from

this

whether

the

driver

’s

side

has

been

successfully

unlocked.

The

CDS

unit

(D905)

will

then

send

via

pin

2

stating

that
