INTERIOR LIGHTING
Courtesy Lamp Control
The body controller has direct control over all of the vehicle's courtesy lamps. The body computer will illuminate the courtesy lamps under any of the
following conditions:
1. Any door ajar and courtesy lamp switch on the headlamp switch is not in the dome OFF position.
2. The courtesy lamp switch on the headlamp switch is in the dome on position.
3. A Remote Keyless Entry unlock message is received.
4. Driver door unlocked with key (with VTSS only).
Illuminated Entry
Illuminated entry will be initiated when the customer enters the vehicle by unlocking the doors with the key fob, or with the key if the vehicle is
equipped with vehicle theft alarm. Upon exiting the vehicle, if the lock button is pressed with a door open, illuminated entry will cancel when the door
closes. If the doors are closed and the ignition switch is turned on, the illuminated entry also cancels. The illuminated entry feature will not operate if
the courtesy lamp switch is in the dome OFF position.
Interior Lighting Battery Saver
If any of the interior lamps are left on after the ignition is turned OFF, the BCM will turn them OFF after 8 minutes. To return to normal operation,
the courtesy lamps will operate after the dome lamp switch or door ajar switch changes state. The glove box and switched reading lamps require that
the ignition be turned to the on/acc position.
Memory System
MEMORY SYSTEM
The memory system consists of power driver's seat, power mirrors and radio presets. The Memory Seat/Mirror Module (MSMM) is located under the
driver's seat. It receives input from the following: driver's manual 8-way seat switch, driver's seat position sensors, PCI bus circuits, and the power
mirror sensors. The module uses these inputs to perform the following functions: position the driver's memory seat, both exterior mirrors (during
recalls), and send/receive the memory system information over the PCI bus.
The Memory Set Switch is wired to the Body Control Module (BCM). A button (either # 1 or # 2) pressed on the set switch causes the BCM to send a
message to the MSMM which in turn will send a motion status message back to the BCM. If the message from the MSMM indicates no current
motion, the BCM will send a recal message to the module. The MSMM will set the seat, exterior mirror and radio to the presets for the indicated
driver.
If any one of the memory controlled systems is inoperative from its manual switch, use the schematics and diagnostic information to correct the
concern. This manual addresses the memory problems only and it is assumed there is not a basic component failure.
POWER SEAT
The memory power seat provides the driver with 2 position settings for the driver's seat. Each power seat motor is connected to the MSMM with two
motor drive circuits. Each circuit is switched between battery and ground. By being able to bi-directionally drive the circuits, the MSMM controls the
movement of the motors based on input from the power seat switch or from the position sensors when performing a memory recall. Each motor
contains a potentiometer to monitor the seat position. To monitor the position of the motor, the MSMM sends out a 5-volt reference on the sensor
supply circuit. The sensor is grounded back to the module on a common ground circuit. Based on the position of the sensor, the MSMM monitors the
voltage change through the sensor on a separate signal circuit.
The MSMM stores the input value of each of the four seat potentiometers in memory when the system requests a set. The driver can initiate a memory
recall, using either the door mounted memory switch or the RKE transmitter (if the remote linked to memory feature is enabled via the EVIC). When
initiated, the MSMM adjusts the four seat sensors (by using the motors) to match the memorized seat position data.
For safety, the memory seat recall is disabled by the MSMM when the vehicle is out of park position or if the speed is not zero. Any obstruction to
seat movement over a 2-second delay will cause the seat to stop moving in which case a stalled motor would be detected by the MSMM and the
corresponding seat output would be deactivated. However, if the object obstructing the seat is removed, the seat will function normally again.
MEMORY MIRRORS
The driver sideview mirror contains vertical and horizontal bi-directional drive positioning motors and position sensors. The MSMM provides a 5-volt
reference on the signal circuit to each position sensor. The sensors share a common ground circuit. The MSMM monitors the position of the mirror
motors by measuring the voltage on each signal circuit. When a memory position is set, the MSMM monitors and stores the position of the outside
mirror. The MSMM adjusts the mirror to the appropriate positions when a memory recall message is received from the RKE or is requested from the
memory set switch.
The power mirror switch during non-memory operation operates the mirror independently of the MSMM.
