door actuator linkages.
Auto Headlamps
The headlamps and park/tail lamps will be activated by the BCM when the headlamp switch is in the auto mode. To activate the auto headlamps the
BCM requires that:
1. The headlamp switch is in the "A" position
2. The engine is running
3. The light level sensed through the sun load sensor falls below the calibrated level
Headlamp Time Delay
The headlamp time delay operates when the ignition switch is turned off while the headlamps are still on, and the head lamps are then turned off within
45 seconds after the ignition is off. The BCM will provide a 90-second time delay before turning off the headlamps.
Mechanical Instrument Cluster (MIC)
The body control module sends the angular position of four gauges, the status of seven indicator lamps, the status and dimming of the PRNDL indicator,
the dimming of cruise and low fuel lamps, and odometer stepper motor information to the Mechanical Instrument Cluster (MIC) over the CCD bus when
the ignition is in the "off" (unlock), "run", or "start" positions.
The PRNDL indicator works when the ignition is in the "off , run , or "start" positions; all other MIC features work only when the ignition is in the "run"
position.
On transition of the ignition from the "off" to the "run" position, a bulb check is performed. This consists of activating all CCD-controlled indicator
lamps and all PRNDL segments for approximately 2-4 seconds. The PRNDL bulb check is aborted if the gear selector is moved from the PARK
position, or if the tachometer exceeds 450 rpm.
Overhead Travel Information System/Homelink (OTIS)
The Overhead Travel Information System (OTIS) gives the driver information that supplements the primary gauge instrumentation. OTIS displays
this information on a vacuum fluorescent display (VFD). The OTIS module has four switch inputs. The buttons for these switches are integral to
the OTIS housing. There are two buttons on each side of the display. The buttons are labelled US/M, STEP, C/T, and RESET. The driver selects
and resets display functions through the use of these four buttons.
The OTIS will display these functions:
-
Compass/Temperature
-
AVE ECO Average Fuel Economy
-
ECO Instantaneous Fuel Economy
-
DTE Distance to Empty
-
ET Elapsed Time
-
ODO Trip Odometer
The OTIS module receives all of its information over the CCD 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 CCD 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.
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.
Other power door lock features:
RKE (Remote Keyless Entry) - This feature allows locking and unlocking of the vehicle door(s) by remote control using a hand-held transmitter
to activate a radio receiver (RKE module). If the vehicle is equipped with vehicle theft security system, it will also arm or disarm that system. The
transmitter can also unlock the trunk while the vehicle is in park and the ignition off. The system was changed in model year 1995 requiring the
trunk release button to be pressed twice to prevent accidental opening of the trunk. The module is capable of retaining two (2) transmitter codes.
To program the transmitter see Body and Frame/Locks/Keyless Entry.
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.
