SOURCE: Bad parking assist sensor.....is there a fuse for the park assist?

This is a shared fuse, if you remove it you will lose other services. As your reverse aid sounds all the time it has a probable fault in the module or wiring. The module is located in the left hand side lower boot. To disable - pull the plugs from the module until you get it checked out. These modules often suffer from dampness in the boot as it is prone to leaking. sometimes just removing and refitting the plugs and then spraying with a water dissipating spray (WD 40) often brings them back to life once they have dried out.
hope this helps - good luck.

Rear Parking Assist Inoperative - Red Indicator Flashes
Does the red indicator flash ?
Diagnostic Aids
• The RPA system is equipped with an on-board diagnostic display feature capable of displaying diagnostic trouble codes from the RPA display. Before using this diagnostics, it is necessary to get familiar and understand how the on-board diagnostic feature operates. Refer to Diagnostic Trouble Code (DTC) Displaying and to Diagnostic Trouble Code (DTC) Clearing on how the diagnostic trouble codes are displayed and cleared from the RPA display system.
• Make sure the rear park assist (RPA) object sensors located on the vehicle rear bumper are clean and clear. Remove any objects that is blocking the sensors.
• Inspect for after market devices which could affect the operation of the RPA system.

Diagnostic Trouble Code (DTC) Displaying

This vehicle is equipped with an on-board diagnostic display feature capable of displaying diagnostic trouble codes using the 3 indicators on the rear parking assist display. After the bulb check has been completed, the red outside indicator flashes to indicate a malfunction with the system. The module disables operation of the URPA system under this condition.
In order to enter the diagnostic mode, complete the following actions:
With the ignition turned OFF, short the rear parking assist diagnostic connector to ground while the vehicle is in PARK. For the location of the rear parking assist (RPA) diagnostic connector, refer to Object Detection Component Views .
Turn ON the ignition.
Place foot on the brake.
Shift the vehicle into REVERSE within 5 seconds.
If the vehicle is not shifted into reverse within 5 seconds after turning the ignition ON, the diagnostic mode will still be initiated. However, a reverse input wiring fault will be registered as sequence #7 as shown in the Diagnostic Indicator table below. Refer to Diagnostic Trouble Code (DTC) Clearing for the specific steps on how to clear diagnostic trouble codes. After the reverse input wiring code is cleared, repeat the diagnostic trouble code displaying steps in order to enter the diagnostic mode.
When the diagnostic mode is first entered, the rear parking assist display displays the amber outside indicator and the red outside indicator. Then, the indicators on the rear parking assist display will display one or more of the sequences in the table below to indicate where the fault exists within the rear parking assist system. Refer to Diagnostic Trouble Code (DTC) Clearing for the specific steps on how to clear diagnostic trouble codes.

The Rear Parking Assist (RPA) Diagnostic Connector (UD7) is under the front of the center console behind the BCM - body control module.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern: Some customers my comment of a Service Park Assist Message on the DIC and/or the LED indicators at the right rear pillar staying on or inoperative. This concern could be caused by the wiring harness to the LED indicators being pinched under a ground eyelet at the right rear pillar, as shown below.

other issues could be the problem such as poor connections at each sensor or damaged sensors. to clear URPA codes,place ignition in run,(engine OFF),shift into reverse and turn key OFF.place shift lever into park and retest operation of URPA. if still inop URPA code(s) need to be retrieved before further diagnosis can be accurately done.

2002 yukon parking assist quit working


{: ) I wonder what quit do you mean? But anyway, there are certain conditions that can disable your park assist temporarily, like the park brakes on, park assist switch disable on, an object is attached to the rear of the vehicle, dirty sensors, overspeed, speed sensors malfunction and more.
If ever one of your sensors are not working, or maybe a module or wiring problem, then it can permanently disable the park assist system, unless the problem is quickly addressed.
The most practical and fast way of tracing the cause is to use a scan tool. It will read all the codes and datas that are relevant to the problem, it can also tell which of the four sensors are at fault, thereby reducing the time of guessing.
For the moment, you can check the VEH B/U fuse 10amp at the underhood fuseblock, and IGN 1 fuse 10amps at the IP fuseblock. Goodluck.

My park assit is on and the sensor are not working for backing up can they have dirt in them


{: ) The PARK ASSIST OFF message will be displayed when the parking assist system is disabled due to conditions that disable or inhibit the system. The object alarm module requests the DIC display PARK ASSIST OFF when it detects one of the following conditions:
• The parking assist system is manually disabled using the driver information center (DIC). • An object is attached to the rear of the vehicle, such as a trailer, bicycle rack, trailer hitch receiver, or tow bar. • The object alarm sensors are covered by snow, mud, dirt, slush, or ice. • The vehicle bumper is damaged. • Excessive paint thickness on a replacement object alarm sensor. • The object alarm sensors are disrupted by vibrations, like those caused by a large nearby vehicle or from heavy equipment such as a jackhammer.

The SERVICE PARK ASSIST message will be displayed when the object alarm module detects a malfunction in the parking assist system and the system is disabled. It could be one of your sensors is at fault or even the module.

The park assist service light comes on when i start the vehicle. i do not have an owners manual to reference.


{: ) The driver information center (DIC) displays SERVICE PARK ASSIST when the object alarm module detects a malfunction in the parking assist system and the system is disabled. The DIC also displays SERVICE PARK ASSIST when a loss of communication occurs with the object alarm module. Usually this is caused by faulty components or wirings. Better visit your dealer if still under warranty, for one park assist sensor only costs too much. If your bumper had been knocked off or had previous repairs outside the dealership, that's another thing.

Normally it will not work when the brakes are worn out so an inspection is needed to determine this is your problem

2005 Lincoln Navigator. Message says to Check


Most likely the problem you are experiencing with the park assist is a fault in one of the sensors mounted in the rear bumper. I would not consider it to be a major fix, however there will be a few hours labor involved as the bumper cover needs to be removed to replace the sensors.
