The keyless entry system allows the driver to use a hand
held radio transmitter in order to perform the following functions outside
of the vehicle:
| | The courtesy lights activate automatically when the door is unlocked. |
| • | Release the rear compartment lid |
| • | Activate the remote alarm |
The transmitter operates on the UHF band. The transmitter digitally
sends the coded signals to the remote door lock receiver (RCDLR) when any
of the remote transmitter buttons are pressed.
The RCDLR detects and decodes the transmitter signals. For all functions
the RCDLR sends command messages to the body control module (BCM) in order
to operate the following components:
| • | The door locks actuators |
| • | The rear compartment lid release relay |
The door lock and lighting systems can be operated by the switches on
inside of the vehicle.
The keyless entry system may be programmed with up to 4 keyless
entry transmitters.
Body Control Module (BCM)
The body control module (BCM) controls the following keyless entry system
functions:
| • | The remote alarm operation |
| • | The rear compartment lid |
Refer to
Body Control System Circuit Description
in Body Control
System.
Diagnostic Trouble Codes (DTCs)
The remote control door lock receiver (RCDLR) sends the door locking
remote alarm and rear compartment lid command messages to the BCM through
the RFA link.
The BCM may set the following DTCs that are related to the keyless entry
system:
Refer to
Body Control System Circuit Description
in Body Control
System.
Keyless Entry Functions
The keyless entry system performs the following functions:
| • | Remote driver door unlock:
The
driver's door unlocks when the UNLOCK button on the keyless entry transmitter
is pressed. |
| • | Remote all door unlock:
All of
the doors unlock when the UNLOCK button on the keyless entry transmitter
is pressed 2 times or more. |
| • | Remote all door lock:
All of the
doors lock when the LOCK button on the keyless entry transmitter is pressed. |
| • | Rear compartment lid release:
The
rear compartment lid opens when the REAR COMPARTMENT button on the keyless
entry transmitter is pressed. |
| • | Remote activation verification:
The headlamps flash and/ or the horn sounds when the keyless entry transmitter
performs any of the remote functions. |
| • | Remote alarm:
The headlamps flash
and the horn sounds alternately for 2 minutes when the ALARM button
on the keyless entry transmitter is pressed. Press the ALARM button again,
within 2 minutes of the initial press, in order to stop the remote
alarm. |
Remote Driver Door Unlock
The RCDLR sends a message to the BCM, through CKT 377, in order
to unlock the driver's door upon pressing the UNLOCK button on the keyless
entry transmitter 1 time.
Remote all Door Unlock
The RCDLR sends a message to the BCM, through CKT 377, in order
to unlock all of the doors upon pressing the UNLOCK button on the keyless
entry transmitter 2 times (allowing no more than 5 seconds
to elapse between presses).
Remote all Door Lock
The RCDLR send a message to the BCM. through CKT 377, in order
to lock all of the doors upon pressing the LOCK button on the keyless entry
transmitter 1 time. The following features alter the normal remote
door locking operation:
| • | The lockout prevention feature:
|
| | The BCM will not lock the doors when the lockout prevention feature
is active. |
| • | The last door closed locking feature:
|
| | The BCM delays the door locking when the last door closed locking feature
is active. |
Refer to
Power Door Locks Circuit Description
in Doors for more information on the
lockout prevention feature and the last closed door locking feature.
Remote Alarm
When the ALARM button on the keyless entry transmitter is pressed, the
RCDLR sends a message to the BCM. The message is sent to the BCM through CKT 377
in order to flash the headlamps and sound the horn alternately for 2 minutes.
Press the alarm button a second time in order to stop the remote alarm.
Rear Compartment Lid Release
When the REAR COMPARTMENT button on the keyless entry transmitter is
pressed, the RCDLR sends a message to the BCM through circuit 377. The BCM
energizes the rear compartment lid release relay and applies voltage to
CKT 56. The rear compartment lid lock release actuator energizes
and releases the rear compartment lid.
If the transmission/ transaxle is shifted out of the PARK position,
the rear compartment lid release feature is disabled.
Courtesy Lights Activation
The BCM turns ON the courtesy lamps when unlocking the doors with the
keyless entry transmitter. Refer to
Interior Lamps System Check
in Lighting Systems.
