ENHANCED ACCIDENT RESPONSE
Upon detection of an airbag deployment by way of the PCI bus, the instrument cluster will:
•
Immediately disable the power door lock output.
•
Unlock all doors by activating the door unlock output for approximately 300 milliseconds.
•
After actuating the door unlock output, allow the door lock motors to be activated if the door lock input has
been inactive (not erratic) for 2 seconds since the reception of the airbag deployment message.
REMOTE KEYLESS ENTRY
A Radio Frequency (RF) type Remote Keyless Entry (RKE) system is an available factory-installed option on this
model. The RKE system allows the use of a remote battery-powered radio transmitter to signal the instrument clus-
ter to actuate the power lock system. The RKE receiver operates on non-switched battery current through a fuse in
the Integrated Power Module (IPM), so that the system remains operational, regardless of the ignition switch posi-
tion.
The RKE transmitters are also equipped with a Panic button. If the Panic button on the RKE transmitter is
depressed, the horn will sound and the exterior lights will flash on the vehicle for about three minutes, or until the
Panic button is depressed a second time. A vehicle speed of about 25.7 kilometers-per-hour (15 miles-per-hour) will
also cancel the panic event.
The RKE system can also perform other functions on this vehicle. If the vehicle is equipped with the optional Vehicle
Theft Security System (VTSS), the RKE transmitter will arm the VTSS when the Lock button is depressed, and
disarm the VTSS when the Unlock button is depressed.
The RKE system includes two transmitters when the vehicle is shipped from the factory, but the system can retain
the vehicle access codes of up to a total of four transmitters. The transmitter codes are retained in the RKE module
memory, even if the battery is disconnected. If an RKE transmitter is faulty or lost, new transmitter vehicle access
codes can be programmed into the system using a scan tool.
This vehicle also offers several customer programmable features, which allows the selection of several optional
electronic features to suit individual preferences. Customer programmable feature options affecting the RKE system
include:
•
Remote Unlock Sequence - Allows the option of having only the driver side front door unlock when the RKE
transmitter Unlock button is depressed the first time. The remaining doors unlock when the button is depressed
a second time within 5 seconds of the first unlock press. Another option is having all doors unlock upon the
first depression of the RKE transmitter Unlock button.
•
Sound Horn on Lock - Allows the option of having the horn sound a short chirp as an audible verification that
the RKE system received a valid Lock request from the RKE transmitter, or having no audible verification.
•
Flash Lights with Lock and Unlock - Allows the option of having the park lamps flash as an optical verifi-
cation that the RKE system received a valid Lock request or Unlock request from the RKE transmitter, or hav-
ing no optical verification.
•
Programming Additional Transmitters - Allows up to a total of four transmitter vehicle access codes to be
stored in the receiver memory.
Certain functions and features of the RKE system rely upon resources shared with other electronic modules in the
vehicle over the Programmable Communications Interface (PCI) data bus network. For diagnosis of these electronic
modules or of the PCI data bus network, the use of a scan tool and the appropriate diagnostic information are
required.
OPERATION
POWER LOCKS
The instrument cluster locks or unlocks the doors when an actuation input signal from a door lock switch or Remote
Keyless Entry (RKE) module is received. The instrument cluster turns on the output drivers and provides a voltage
level to the door lock motor for a specified time. All passenger doors can be locked or unlocked using a mechanical
button mounted on the door trim panel. The drivers door can be locked or unlocked by using the key cylinder.
AUTOMATIC DOOR LOCKS
When the automatic door locks are ENABLED the door locks will lock when the vehicle is moving at about 25.7
Km/h (15 mph), all doors are closed and the accelerator pedal is depressed. This feature can be switched ON or
