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 release rear release
button 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. |

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. The RVS feature is started
by the customer pressing and releasing the lock button and then pressing and holding
the 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 RVS 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 RVS Continue. This allows a maximum of 20 minutes
of engine running via the RVS feature without a reset. If the RVS 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 DIC, the RVS feature can be DISABLED and ENABLED just like other items
programmable via the DIC. When a lock control, entry-remote entry, extended range
(AP8) equipped vehicle has RVS added to it and the vehicle is not DIC equipped and
the customer wants to disable RVS. The dealer will perform the DISABLED remote start
function since the owner cannot perform the function on thier own without a DIC.
Remote Vehicle Start Features That Allow A Remote Vehicle START/CONTINUE
• | The RVS feature must be enabled. |
• | A RVS 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 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.
