Keyless Vehicle System Overview

The keyless vehicle system also incorporates RKE
functions, however the main purpose of the system
is to allow the operator of the vehicle to gain access
to and operate the vehicle without carrying out any
actions with a key or remote buttons.

The keyless vehicle system can be turned off to
give basic key operation if required.

To isolate the keyless vehicle system, the
emergency key must be inserted into the ignition

switch turning knob and the ignition switch turning
knob rotated to position II. It is now possible to
select the KEY FREE ON or KEY FREE OFF from
the instrument cluster liquid crystal display (LCD)
using the remote steering column stalk control. In
the OFF mode, the RKE functions still work.

Vehicles equipped with keyless vehicle systems,
will be delivered from production in shipping mode.
Shipping mode reduces the vehicle battery drain
to a minimum to extend the period of time the
vehicle can remain dormant without discharging
the vehicle battery.

To exit the shipping mode, the emergency key must
be inserted into the ignition switch turning knob
and rotated to position II. The shipping mode can
now be deselected from the instrument cluster LCD
display using the steering column stalk control.

The passive vehicle key can receive an
identification challenge from the vehicle door
exterior handle keyless vehicle antennas within a
range of approximately 1.5 meters to 2.0 meters.
The challenge from the rear exterior keyless vehicle
antenna will be received at up to 1.5 meters from
the center rear of the vehicle. On receiving the
identification challenge, the passive vehicle key
will emit a coded radio frequency (RF) signal to the
RF receiver. No RF signal will be emitted if the
passive vehicle key does not recognize the coded
low frequency challenge from the keyless vehicle
module.

If the system is functioning correctly, the operator
will be able to open the vehicle doors, liftgate or
luggage compartment lid, as long as a valid passive
key is within the defined areas.

If a valid passive vehicle key detects a low
frequency challenge from the interior keyless
antenna and emits a valid RF coded signal, the

keyless vehicle module will switch on the passive
go functionality.

If a valid passive vehicle key is left in the vehicle
and the vehicle is locked using a second valid
passive vehicle key. The instrument cluster will
indicate the presence of a valid key in the vehicle
and the passive vehicle key left in the vehicle will
be disabled. The disabled passive vehicle key can
only be reactivated by starting the vehicle with the
emergency key.

Up to 8 passive vehicle keys can be programmed
to one keyless vehicle module. Passive vehicle
keys can only be programmed using the Teach
Keys menu in WDS.

DIAGNOSIS AND TESTING

E56103

The passive vehicle key is equipped with RKE
function buttons. When an RKE function button is
pressed, the RF signal emitted is received by the
RF receiver within the vehicle. Data is sent from
the RF receiver to the keyless vehicle module. The
keyless vehicle module will validate the transmitted
signal and if valid, operate the relevant function.

Within the passive vehicle key is concealed a
emergency mechanical key. The mechanical key
can be used to open the drivers door and start the
vehicle. The mechanical key is equipped with a
passive anti-theft system (PATS) transducer.

To start the vehicle with the emergency key, it must
first be assembled to the ignition switch turning
knob insert. When the assembled key is inserted
into the ignition switch turning knob, the key
insertion detection switch sends a signal to the
keyless vehicle module indicating a key has been
inserted. The keyless vehicle module will then
switch off the passive go and revert to standard
PATS functionality.

The emergency key will override the ignition lock
cylinder electrical locking function.

Mechanical key insertion detection switch

Steering column lock

Steering column lock pin

The steering column lock control unit still carries
out the same function as the standard steering
column lock, but now it has the added functionality
of a solenoid operated ignition lock cylinder
release.

For the steering column lock to release in keyless
vehicle mode, certain criteria must be fulfilled:

• vehicles with automatic transmissions must have

the brake pedal pressed

• vehicles with manual transmissions must have

the clutch pedal pressed

• a valid passive vehicle key must be within the

detection range of the interior keyless vehicle
antenna

When the brake or clutch pedal is pressed, the
keyless vehicle module is triggered to search for
a valid passive vehicle key. If a valid passive
vehicle key is detected, the ignition lock cylinder
solenoid releases and the ignition switch turning
knob can be pressed in. This will release the
steering lock and allow the ignition switch turning
knob to be rotated to positions I, II and III.

To lock the steering column, the ignition switch
turning knob must be turned to the 0 position and
pulled out by approximately 5mm.

The PATS function is armed until the ignition switch
turning knob has reached position II. When the
ignition switch turning knob is in position II, the
keyless vehicle module receives a request from
the steering column lock control unit to identify the
passive key PATS transducer. The keyless vehicle
module then sends a command on the medium
speed CAN bus to the instrument cluster. The
instrument cluster verifies the validity of the passive
vehicle key PATS transducer and in turn
communicates with the powertrain control module
(PCM) and allows the vehicle to start.

If a new steering column lock control unit is
installed to a vehicle, before it will function, it must

be initialized using the Initialize System menu in
WDS.

Liftgate/Luggage Compartment Lid Lock
Button

E56178

The liftgate/luggage compartment lid lock button
is located in the licence plate illumination panel.

If the liftgate/luggage compartment lid is closed
and the exterior lock button is pressed while a valid
passive vehicle key in the loadspace area, the
keyless vehicle module will request that the
external keyless vehicle antennas issue a passive
vehicle key challenge. If no valid passive vehicle
key signal is detected by the RF receiver, the
liftgate/luggage compartment lid will be
automatically opened. If a valid passive vehicle
key signal is detected by the exterior keyless
vehicle antennas, the passive vehicle key in the

loadspace area will be deactivated and the vehicle
allowed to lock in the normal way. The deactivated
passive vehicle key will be reactivated after the
ignition switch turning knob has been turned to
position II with either a valid passive vehicle key
or a mechanical emergency key.

Interior Keyless Vehicle Antenna

E56100

The interior keyless vehicle antenna function is to
issue a low frequency challenge to the passive
vehicle key while it is in the passenger
compartment.

The vehicle is equipped with two interior keyless
vehicle antennas in the passenger compartment
area and one in the loadspace area.

The loadspace keyless vehicle antenna is fitted to
prevent the possibility of accidently locking the
passive vehicle key in the loadspace area.

Description

Item

Exterior door handle

Exterior keyless vehicle antenna

Exterior door lock switch

With the vehicle locked and the keyless vehicle
system active, the exterior keyless vehicle
antennas are dormant and do not scan for a valid
passive vehicle key. The exterior keyless vehicle
antenna will only wake up and issue a challenge
for a valid passive vehicle key when the operator
has begun to pull the exterior door handle.

In the time it takes to open a door, the signal
determining handle movement is sent to the
keyless vehicle module, a request of the exterior
keyless vehicle antenna to detect a valid passive
vehicle key, the receiving and validation of the
passive vehicle key code and the command to the
door latch to unlock has occurred. This whole
process takes approximately 150 ms.

The only time this function will be impaired is if the
vehicle has been left standing for at least 5 days.
The keyless vehicle module will then enter a state
of reduced energy consumption and when the

vehicle door handle is pulled, it will take a
noticeably increased period for the keyless system
to wake up and unlock the door(s).

When the operator exits the vehicle, the vehicle is
locked by pressing the lock button fitted into the
exterior door handle.

With all doors and liftgate/luggage compartment
lid closed, the exterior door lock button will initiate
a request from the keyless vehicle module to scan
the interior and exterior of the vehicle around the
pressed lock button for valid passive vehicle key.
If a valid passive vehicle key is detected on the
exterior of the vehicle only, the door latches will be
locked. The door latches will remain locked for a
period of 3 seconds to allow for the operator to pull
the exterior door handle to check if the door is
locked. After 3 seconds, if the exterior door handle
is pulled, the door latch will release as in a normal
keyless vehicle entry. If a valid passive vehicle key
is detected in the interior of the vehicle and not on
the exterior, the latches will not be locked. The
vehicle will also not be locked if the ignition switch
turning knob is in the II position. Passive vehicle
locking will be confirmed by the operation of the
vehicles turn signal lamps.

DIAGNOSIS AND TESTING

If the ignition turning knob is in position I or 0 and
the steering column lock is not engaged, the
keyless vehicle module will allow the locking to
operate. A warning chime will sound and a warning
ENGAGE STEERING LOCK will be displayed in
the instrument cluster LCD area if driver's door is
opened.

To double lock the vehicle, requires the exterior
lock button to be pressed twice. The second
pressing of the exterior lock button must occur
within 3 seconds of it first being pressed.

To operate the global closing feature, requires the
exterior lock button on the drivers door only, to be
pressed and held pressed for a period of 2
seconds.

The keyless vehicle central unlocking function can
be programed to operate the drivers door only or
all the doors. To set the desired function, the lock
and unlock button at the passive key has to be
pressed in parallel for 4 seconds. If a rear exterior
door handle or passenger exterior door handle is
pulled when the keyless vehicle system is in driver
door unlock mode, all doors will remain locked. If
the driver exterior door handle is pulled when the
keyless vehicle system is in driver door unlock
mode, only the driver door will unlock and the door
handle passive entry for the rear doors and
passenger door will be inoperative.

In driver door unlock mode, the passenger doors
can only be unlocked using the interior keyless
vehicle system unlock button.
