The keyless entry system is a supplementary vehicle entry device. Radio frequency
interference or discharged batteries may disable the system.
Keyless entry allows you to operate the following features:
| • | The rear compartment lid release--Press and hold rear release button
for approximately one second to activate. |
| • | The illuminated entry lamps. |
The keyless entry system has the following main components:
| • | The body control module (BCM) |
| • | The remote control door lock receiver (RCDLR)--When you press a button
on the transmitter, the transmitter sends a signal to the RCDLR. The RCDLR receives
the signal and sends a X Link serial data message requesting the appropriate function
from the BCM. |
Unlock Driver Door Only
Momentarily press the UNLOCK button in order to perform the following functions:
| • | Unlock the driver door only. |
| • | Illuminate the interior lamps for approximately 20 seconds or
until the ignition is turned ON. |
| • | Flash the park lamps if the ignition is turned OFF and the doors are closed. |
| • | Identify the driver to the radio--The radio will then revert to the
station presets, the last station, the last volume settings, and the last playback
mode used by that driver. |
Unlock All Doors - Second Operation
Momentarily press the UNLOCK button a second time, within 5 seconds
of the first press, in order to perform the following functions:
| • | Unlock all of the doors. |
| • | Illuminate the interior lamps for approximately 20 seconds or
until the ignition is turned ON. |
Lock All Doors
Press the LOCK button in order to perform the following functions:
| • | Immediately turn OFF the interior lamps. |
| • | Flash the park lamps if the ignition is OFF and the doors are closed. |
| • | Chirp the horn if the ignition is OFF and the doors are closed. |
Remote Trunk/Liftgate Release
The trunk or liftgate will open when this button on the transmitter is pressed
and held for approximately one second. You can open the sedan trunk with the transmitter
when the vehicle is stationary. On vehicles equipped with a liftgate the liftgate
will only open when the vehicle is in PARK (P).
Panic Alarm Function
A single press of the panic button performs the following functions:
| • | Illuminates the interior lamps. |
| • | Flashes the daytime running lamps for 2 minutes or until the following
conditions occur: |
| - | The panic button is pressed again. |
| - | The ignition switch is turned to the RUN position with a valid key. |
Remote Vehicle Start
The Remote Vehicle Start function allows the customer to start the vehicle while
not in the car. It also allows starting up the vehicle heating or air conditioning
system and other vehicle systems to provide the customer with a comfortable vehicle
when they enter it. The distance the customer can be away from the vehicle and operate
this feature has a design requirement of 60 meters or 100 feet. The
Remote Vehicle Start feature is started by the customer pressing and releasing the
lock button and then pressing and holding the remote vehicle start (RVS) buttons on
their key fob. The turn signal lamps will flash if this feedback is enabled on to
indicate the vehicle has received the Remote Start Request. Each time the customer
does a remote vehicle start, the vehicle doors are locked, however they may then be
unlocked/locked with the key fob or key at anytime. Once the vehicle has been started,
there is visible feedback. There are vehicle conditions which will prevent a remote
start, for example if the hood is not closed or the key is in the ignition. The Remote
Vehicle Start feature once activated is allowed to run for 10 minutes. At any
time during this 10 minute time the 10 minute time-out can be reset
once. This feature is called a Remote Vehicle Start Continue. This allows a maximum
of 20 minutes of engine running via the Remote Vehicle Start feature without
a reset. If the Remote Vehicle Start Continue is done at 7 minutes into the
initial 10 minute time-out, a total of 17 minutes of engine running
would occur. A remote vehicle start, once active, can be stopped by pressing a dedicated
RVS button on the key fob or by pressing the Vehicle Hazard switch located inside
the vehicle . the following will also abort a remote start, using an invalid passkey
, force rotating the ignition, force shifting out of park. Remote start will also
be stopped if any DTCs that turn ON the SES/MIL are stored in history or current status.
Customer Programming Method for Enabling/Disabling the RVS Feature
Using the driver information center (DIC), the RVS feature can be DISABLED and
ENABLED just like other items programmable via the DIC.
Remote Vehicle Start Features That Allow A Remote Vehicle START/CONTINUE
| • | The remote vehicle start (RVS) feature must be enabled. |
| • | A remote vehicle start request command is received by the body control
module (BCM). |
| • | The hood ajar switch status is closed. |
| • | The number of remote start attempts is less than 3. |
| • | The key is not in the ignition. |
| • | The remote start voltages are within proper operating ranges 6-16 volts. |
| • | There are no DTCs or serial data communication failures with RVS related
systems. |
| • | The transmission status is Park/Neutral and the vehicle speed is zero. |
Conditions to Stop A Remote Vehicle Start
| • | Hood ajar switch status is - OPEN. |
| • | Inserting the key in the ignition and turning the key to any non-off power
modes, and returning the key to the OFF position |
| • | The remote vehicle start (RVS) time has elapsed or timed out. |
| • | The RVS master receives a run abort message from the powertrain control
module (PCM). |
| • | Hazard shutoff switch status is - ACTIVE. |
| • | By content theft deterrent (CTD) system, if equipped, and alarm status
becomes Violated |
| • | RVS system voltage out of range, under 6 volts or over 16 volts |
| • | DTCs set for any related systems, or serial data communication failure
for any modules that support the RVS function |
If the RVS master stops a remote vehicle start for any of these conditions,
further remote vehicle starting is not allowed until a RVS RESET has occurred.
A RVS Reset occurs when, in an ignition switch vehicle, the key is inserted
and rotated into the Run position, power mode of RUN is seen, and PCM Vehicle Theft
Fuel Continue is received over serial data and passes VTD criteria.
This action results in resetting the RVS counters to MAX starts allowed and
the RVS Attempts to 0.
