If the vehicle is equipped with the optional Homelink feature, the OTIS will have three buttons
located in the center of the OTIS module. The OTIS module receives all of its information over the
PCI bus except compass, which is internal to the OTIS module. The OTIS powers up when it
recognizes vehicle voltage on the ignition input circuit. OTIS blanks the display, then illuminates
all segments of the VFD. It then blanks the display again. During this time, the OTIS sends and
receives information over the PCI bus to determine what to display after the two-second
initialization. The OTIS displays dashes (- - -) for any of the screens for which it did not receive
bus messages during the two-second initialization. These dashes will be replaced by valid
information if and when it is received from the bus.
3.12 Power Door Lock System
The door lock switches provide a variable amount of voltage through the multiplexed (MUX) circuit
to the BCM. Depending upon that input and various conditions that must be met (i.e. door lock
inhibit, etc.), the BCM will determine the action to be taken and activate the proper relay for
approximately 250 to 350 msec. If the vehicle is equipped with the vehicle theft security system
it will have the central locking feature which locks and unlocks all doors from the door key cylinder
switches. These switches are on separate multiplexed circuits to the BCM and have trouble codes
relating to each of them.
RKE Remote Keyless Entry - This feature allows locking and unlocking of the vehicle door(s) by
remote control using a hand-held transmitter (sometimes referred to as a fob) to activate a radio
receiver (RKE module). This module now plugs into the body control module which is directly
connected to the junction block. With this feature RKE can now be added to a non-equipped
vehicle by installing a module. If the vehicle is equipped with the vehicle theft security system,
RKE will also arm and disarm that system. A new 4-button transmitter is used this year which will
provide lock, unlock, decklid release and panic features. Decklid release is only operable while
the vehicle is in the park position. The module is capable of retaining up to 4 transmitter codes.
Rolling code, which increases security, has been added this year. If the transmitter goes out of
synchronization it is easily put back in by pressing the lock button when the transmitter is within
range. An external antenna has been added which plugs into the module to provide greater range.
RKE will also turn on the interior lamps when a valid unlock command is received and will
extinguish the interior lamps when a lock command is received and all doors are closed.
On a vehicle equipped with the memory system, when the unlock button on a specified transmitter
(either #1 or #2) is pressed the BCM will send a recall message to both the MHSMM and the PCI
radio. They will in turn position the left seat and both mirrors along with setting the radio presets.
Door Lock Inhibit - When the key is in the ignition and the left front door is open, all door lock
switches are disabled. The unlock switches are still functional. This protects against locking the
vehicle with the keys still in the ignition.
Automatic (rolling) Door Locks - This feature can be enabled or disabled by using either the DRB
or the customer programmable method. When enabled, all doors will lock when the vehicle
reaches a speed of 24 KMH (15 MPH) and all doors are closed. If a door is opened and the vehicle
slows to below 24 KMH (15 MPH), the locks will operate again once all doors are closed and the
speed is above 24 KMH (15 MPH).
Decklid Release - Decklid release is now a function of the body control module. Trouble codes are
provided to assist in the diagnosis of this system.
