Town & Country V6-4.0L (2008)
A park assist system is an optional factory-installed electronic parking aid. During parking and other similar vehicle maneuvers this system alerts the
vehicle operator to obstacles located in the path immediately behind the vehicle which, due to the surrounding rear vehicle structure, might be otherwise
difficult to perceive. When an object is detected, the system uses an electromechanical transducer and Light Emitting Diode (LED) indicators within the
park assist display unit to provide the vehicle operator with visual and audible indications of the presence and proximity of such objects.
The park assist system includes the following major components, which are described in further detail elsewhere in this service information:
-
Electronic Vehicle Information Center (1) - In vehicles equipped with the optional park assist system, the optional Electronic Vehicle
Information Center (EVIC) in the instrument cluster displays textual warnings and error messages and emits audible warnings related to the current
operating status of the park assist system and provides an interface that allows the vehicle operator to manually disable or enable the system using
the customer programmable features option. The park assist system can also be manually enabled or disabled on vehicles equipped with the
Compass Mini Trip Computer option. This can
-
Park Assist Display (3) - Vehicles equipped with the park assist system have a park assist display unit mounted in the upper liftgate opening
header trim molding. The body of the display is concealed above the molding where it is secured by a molded plastic retainer on the back side of
the molding. Only the narrow, oval-shaped smoked clear lens of the display is visible on the outer surface of the molding.
-
Park Assist Module (2) - Vehicles equipped with the park assist system include a park assist module which is secured through integral mounting
tabs by a push-in type fastener to the quarter inner panel above the forward end of the right rear wheel housing where it is concealed beneath the
quarter inner trim.
-
Park Assist Sensors (4) - Vehicles equipped with the park assist system have four ultrasonic park assist sensors that are concealed behind the rear
bumper fascia. Each sensor is snapped into an individual molded plastic mounting bracket secured at horizontal intervals along the back side of the
rear bumper fascia.
Hard wired circuitry connects the various park assist system components to each other through the electrical system of the vehicle. These hard wired
circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be
connected to each other and to the vehicle electrical system through the use of a combination of soldered splices, splice block connectors, and many
different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information in Diagrams/Electrical. The wiring
information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as
pin-out and location views for the various wire harness connectors, splices and grounds.
The park assist system components cannot be adjusted or repaired. If any of the park assist system components is damaged or ineffective, that component
must be replaced.
