Durango 2WD V8-4.7L Flex Fuel (2009)
emits a single half-second audible beep. As the vehicle comes to within about 50 centimeters (19.7 inches) of the object, all of the amber indicators and
the first red LED indicator are illuminated and the display emits a series of short, intermittent, audible beeps. If the audio system is turned ON, the audio
output will be muted automatically while the park assist audible warning is being generated. The audible warning changes from intermittent beeps to a
continuous tone as the final red indicator is illuminated and the vehicle comes to within 30 centimeters (11.8 inches) of a detected object.
When the park assist module monitors a problem in any of the park assist system circuits or components, it stores a fault code or Diagnostic Trouble
Code (DTC) in its memory circuit, illuminates all four red LED units in the park assist display, sends an electronic message to the EVIC, and a
SERVICE PARK ASSIST SYSTEM textual message is displayed in the EVIC display.
The hard wired circuits between components related to the park assist system may be diagnosed using conventional diagnostic tools and procedures.
Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of
wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
However, conventional diagnostic methods will not prove conclusive in the diagnosis of the park assist system or the electronic controls or
communication between modules and other devices that provide some features of the park assist system. The most reliable, efficient, and accurate means
to diagnose the park assist system or the electronic controls and communication related to park assist system operation requires the use of a diagnostic
scan tool. Refer to the appropriate diagnostic information.
