NOTE: In order for engine starting to be enabled
it is necessary for a valid passive key to be present
inside the vehicle.
Three interior antennas are installed in the vehicle:
• one behind the instrument panel,
• one under the floor console,
• one behind the rear seat bench.
Three states can be switched to via the start/stop
button:
• Switch on the ignition
• directly start the engine,
• switch off the engine.
The following options are available:
• Ignition ON:
– actuate the start/stop button.
• Starting the engine from ignition ON or directly
from ignition OFF:
– Vehicles with manual transmission: Depress
the clutch pedal and press the Start/Stop
button.
– Vehicles with automatic transmission:
Depress the brake pedal and press the
Start/Stop button.
When the start/stop button is pressed, the interior
antennas of the keyless vehicle module are
activated.
The passive vehicle key is thereupon activated and
emits a coded radio signal.
The coded radio signal from the passive key is
received by the radio frequency receiver.
The radio frequency receiver transfers the signal
to the keyless vehicle module.
If the keyfree module recognizes a valid code, a
coding enquiry is made to the PCM.
The coding enquiry is made over the HS-CAN.
Only when the PCM approves the coding enquiry
is the start enable issued.
Switching off the engine
The engine is switched off by actuating the
start/stop button, provided the vehicle is stationary
(vehicle speed = 0 km/h).
The engine can be stopped in an emergency as
follows:
• Press the Start/Stop button three times within
two seconds or
• press the Start/Stop button and hold it pressed
for three seconds.
Component Description
Start/stop button
For safety reasons the Start/Stop button is
designed with two switch functions. It therefore
sends the actuation signal to the keyless vehicle
module over two separate cables.
When a valid key is recognized, the engine is
switched on or off or started via the Start/Stop

Steering Column Lock Control Unit

PATS (passive anti-theft system)
transceiver
Comments:
only relevant for the emergency start
function

The steering lock unit is attached to the steering
column.
The steering lock unit comprises:
• a DC motor with a locking pin,
• integrated control electronics.
Actuation is via the keyless vehicle module.
The steering lock unit communicates with the
keyless vehicle module via a private data bus
(K-wire).
The steering lock unit is unlocked:
• by opening the driver's door:
– Signal from the door contact switch to the
GEM, then from the GEM via the MS-CAN
to the keyless system module.
• when the ignition is switched on (if the Start/Stop
button is not pressed within 45 seconds of the
driver's door being unlocked),
• when the clutch or brake pedal is depressed.
When the vehicle is unlocked or the ignition is
switched on, the steering column lock unit is
supplied with battery voltage from the keyless
vehicle module. The unlocking routine then
commences:
• The keyless vehicle module checks the status
of the steering lock unit. In addition, the
identification code is queried (i.e. whether a
correctly programmed steering lock unit is
connected).
• Following successful completion of the
check/identification, the DC motor is actuated
by the control electronics and the steering lock
is released.
The steering column lock will be locked when the
vehicle is locked or after 45 seconds, if the
following conditions are met:
• Engine OFF,
• Ignition OFF,
• vehicle speed 0 km/h.
– Depending on the software version, the steering
wheel lock can only be locked if there is no
passive key in the vehicle.

DESCRIPTION AND OPERATION
201
Emergency starting function
If the keyless vehicle system is unable to recognise
the passive key, the vehicle can be started via the
emergency starting function.
To do this, a conventional transceiver is installed
on the steering column lock unit.
To start the engine, the passive key must be held
near the steering column lock unit (see current
Owner's Manual). Then press the Start/Stop button
with the clutch or brake pedal depressed.
Service Instructions
Vehicles with Keyless Vehicle System
A total of up to eight passive vehicle keys can
be programmed.
All available passive vehicle keys must be
reprogrammed using IDS if one or more passive
keys are to be added.
After the keyless vehicle module has been
changed, all the available passive vehicle keys
must be reprogrammed using IDS.
In addition, the keyless vehicle module must be
initialized with the following modules using IDS:
• PCM,
• steering lock unit.
After a new steering lock unit is installed,
initialization must be performed with the keyless
vehicle module using IDS.
After a new PCM has been installed IDS must be
used to initialize it with the keyless vehicle module.
Vehicles without Keyless Vehicle System
Up to eight remote controls can be programmed.
All available remote controls must be
reprogrammed if one or more remote controls are
to be added.
The remote controls can be programmed either
using IDS or by running through the following steps:
1. Disable the alarm system (if installed) and
unlock the vehicle.
2. Turn the ignition on and off four times within 6
seconds.
3. Turn off the ignition and leave the ignition key
in the ignition lock. A signal tone sounds to
confirm that programming mode is active.
4. Press any button on the remote control within
10 seconds. A signal tone sounds to confirm
that the remote control has been programmed.
5. Repeat step 4 with all other existing remote
controls.
Programming mode is deactivated if:
• No buttons on a remote control are pressed
within 10 seconds after the signal tone,
• The position of the ignition lock is changed,
• The maximum number of 8 remote controls has
been programmed.
The unlocking function of the central locking
works in two ways:
• Pressing the unlock button on the remote control
unlocks all doors.
• Pressing the unlock button on the remote control
unlocks only the driver's door. Pressing the
unlock button again within 3 seconds unlocks
all doors.
To reprogram the unlocking function, run
through the following steps:
1. Switching the ignition OFF.
2. Simultaneously hold down the unlocking and
locking buttons on the remote control for at least
4 seconds.
3. Reprogramming is confirmed by the turn signals
flashing twice.
Repeat these steps to revert to the previous
functioning.

Principles of Operation (Vehicles with
Remote Keyless Entry (RKE)
RKE locking system overview
This system consists of mechanical/electrical
operated door latches driven by outputs from the
generic electronic module (GEM). The system uses
a radio frequency transmitter and receiver to
operate the remote lock/unlock functions and
normal key or inner door handle inputs for standard
central and double locking functions.
When the normal key or inner door handle is
operated, switching contacts within the door latch
supply a command signal to the GEM. Dependant
upon the current state of the locking system, the
GEM allows battery voltage to be applied to the
door latch motors.
The liftgate or luggage compartment lid is opened
when the vehicle is in the unlocked mode by a
ground signal from the liftgate or compartment lid
release switch to the GEM. The GEM will supply
a voltage to the liftgate or compartment lid latch
motor.
If the vehicle is locked, the input from the liftgate
or compartment lid release switch will be ignored.
The RKE functions are operated by sending a radio
frequency signal from the key transmitter and the
signal is received by the GEM. For vehicles
equipped with the keyless system the radio
frequency signal is transferred to the keyless
vehicle module and a signal is transmitted to the
corresponding lock sent via controller area network
(CAN) to the GEM module.
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.
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.
Inspection and Verification (Vehicles
with Remote Keyless Entry (RKE)
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical
or electrical damage.
