Park Assist Doesn't work On 2007 Solara

See the awd fuse in under hood fuse box, not only check the fuse, use a test light and check voltage on fuse circuit, key on. There shows to be four park assist sensors at the rear bumper, they have three wire connector, that is ref voltage--ground--signal. You also have a rear park assist module, At the moment, I don't know where that is located? Any applicable trouble codes relating to rear park assist? I have some text explaining the operation, but, not really any troubleshooting sequence.

I’m happy to assist further over the phone at https://www.6ya.com/expert/howard_977676954994c5b2

sensors are not working correctly ...be careful when parking as the warning system may not sound or you may be actually closer than the beeping sound indicates

Check with a diagnostic scan tool for module fault codes and sensor fault codes. If nothing comes back complete electrical circuit prove out.

Back of the bumper

#PIT4878: Service Park Assist Message / LEDs Stay On Or Inop - keywords B0968 inoperative lamp led light lit module reverse urpa - (Jun 12, 2009) Subject: Service Park Assist Message/ LED's Stay On or Inop Models: 2007-2009 Chevrolet Silverado 2007-2009 GMC Sierra With RPO UD7

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.

{: ) 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 long beep is to tell you its on.try asking someone to walk past when your in reverse about 18 inches from the bumper if it dont beep beep then try cleaning sensors.if that dont work then a sensor could be faulty..

faulty sensor in teh bumper or bad connection, im not sure where the main module is on them. most likely in rear pannel, dr or pass side, check for rock beaten wires under the back of the van.
