Pacifica V6-3.8L VIN L (2005)
Flash programming voltage - When a DRBIII(R) is connected and the proper flash reprogramming sequence is selected, the 20 volt signal will be
applied through pin 5 of connector C9.
CAUTION: The IPM will learn several Learned Features when it is connected to a vehicle, therefore it is not recommended that IPM's be swapped
from one vehicle to another or false DTC's could be stored in the module and could not be erased.
Interior Lighting
COURTESY LAMP CONTROL
The Body Control Module (BCM) has direct control over all of the vehicle's courtesy lamps except for the driver and passenger front courtesy lamps.
The Driver Door Module (DDM) and the Passenger Door Module (PDM) turn these lamps on based on requests sent over the PCI Bus from the BCM.
The courtesy lamps will illuminate if:
-
Any door is ajar and the courtesy lamp switch on the headlamp switch is not in the dome off position.
-
The courtesy lamp switch on the headlamp switch is in the dome on position.
-
A Remote Keyless Entry unlock message is received.
-
The operator unlocks the driver door with the 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.
-
The operator unlocks the driver door with the key (with VTSS only).
Park Assist System
The Park Assist System display activates an audible tone that changes from intermittent to continuous as the final two Light Emitting Diodes (LED's) are
illuminated on one side or both sides of the display.
The system detection length from the rear of the vehicle is 0.3 meters to 1.5 meters. This area extends around the rear side of the vehicle. The system
detection height from the ground is 0.2 meters to about 1.5 meters. The radio mutes when the system activates its audible tone.
When the driver selects Reverse or Neutral the system scans for objects behind the vehicle using four sensors located in the rear bumper. Objects can be
detected from up to 1.5 meters. A warning display above the rear window provides both visible and audible warnings indicating the range of the object.
The system is active only when the vehicle is in reverse or neutral for vehicle speeds less than 16 Km/h (10 mph). If the vehicles Parking/Emergency
Brake is applied, the system is deactivated.
The display contains two sets of yellow and red Light Emitting Diode's (LED's) that the driver can see in the rear view mirror. Each side of the vehicle
has its own warning LED's. The system provides a visual warning by illuminating one or more yellow LED's as the vehicle gets closer to the object. As
the vehicle continues to approaches the object, one red LED is illuminated and the system emits a series of short beeps. The tone will remain constant
and both red LED's are illuminated once the vehicle is within 12 inches (30.5 cm) of the object.
The system can be turned ON or OFF through the Electronic Vehicle Information Center (EVIC) when the vehicle is in PARK. If the park assist system
is turned OFF, a single chime will sound and the EVIC will display the following message "REAR PARK ASSIST OFF", when the vehicle is in reverse.
-
Ensure that the rear bumper is free of dirt and debris to keep the system operating properly.
-
Jackhammers, large trucks, and other vibrations could affect the performance of the system.
-
Ensure that the parking brake is not applied.
If "Service Park Assist System" appears in the EVIC after making sure the rear bumper is clean, proceed to diagnose the system using a scan tool and the
appropriate diagnostic information.
Memory Seats
POWER SEAT - DRIVER
The memory power seat provides the driver with 2 position settings for the driver's seat. Each power seat motor is connected to the MHSAPM/MSAPM
with two motor drive circuits. Each circuit is switched between battery and ground. By being able to bi-directionally drive the circuits, the
MHSAPM/MSAPM 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 MHSAPM/MSAPM 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 MHSAPM/MSAPM monitors the voltage change through the sensor on a separate signal circuit.
