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.

How do I get rid of my "Service Park Assist" message?

{: ) The "Service Park Assist" message cannot be erased or reset until the main cause of the problem is resolved. It will just keep on coming back. Let's say one or more of the park assist sensors are faulty, you should have it repaired or replaced first before the scan tool can successfully clear the trouble codes that were present then.
The SERVICE PARK ASSIST message is a reminder that a fault has been detected by the parking assist system and it will disable this system until the problem is being addressed. A scan tool can effectively trace the cause of the fault.

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.
The PARK ASSIST OFF message is displayed in the DIC 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.

Park assist warning came on.

{: ) SERVICE PARK ASSIST The driver information center (DIC) displays SERVICE PARK ASSIST when the park assist module detects a malfunction in the object detection system and sends a request to the DIC for display of the message. The DIC also displays SERVICE PARK ASSIST when there is a loss of communication with the park assist module.
PARK ASSIST OFF The PARK ASSIST OFF message is displayed in the DIC when the park assist system is disabled due to conditions that disable or inhibit the system. The red LED in the rear display, as well as, the telltale in the switch will be lit, notifying the driver the PARK ASSIST system is disabled. The object alarm module requests the DIC via the serial data circuit to display PARK ASSIST OFF when it detects that one of the following conditions is true:
• The object alarm system is disabled through DIC vehicle customization feature. Refer to the Owners Manual for more information. • An object is attached to the rear of the vehicle, such as a trailer, bicycle rack, or hitch receiver. • An object is hanging out of the endgate. • The park brake is not fully released. • The system receives vibrations from a large nearby vehicle or from a heavy equipment such as a jackhammer. In the case of objects attached to the rear of the vehicle such as a trailer, hitch receiver, or a bicycle rack, or objects hanging out of the endgate, the rear parking assist (RPA) will have an Automatic Object induced disable feature where the RPA will determine if the rear object is moving with the vehicle. If the RPA detects such a condition, the park assist will be disabled. The PARK ASSIST OFF message will continue to be displayed until the trailer hitch receiver is removed and the vehicle is driven forward above 24 km/h (15 mph).

What does "service park assist system" mean on my 2008 jeep?

The park assist system detects objects 59 inches or less in back of your vehicle, to warn u so u don't strike the object. I'm guessing that since the service park assist system comes on in the ice and snow, the monitor is detecting something (ice and snow covering the sensor). If u clean off the snow and ice, the message should shut off.
