2014 Yukon XL Service Park Assist warning

[JulianG]

Just got this truck seams great the only thing is I get park assist warning.
When put in reverse all rear sensors appear to work ok and seem to work alarming correctly, however when I put it in drive after a very short distance the service park assist comes on and the button that allows you to switch it off flashes. I understand there is a control module but I am unable to find it.

Any suggestions would be greatly appreciated.

Did you ever figure this out? I have the exact same problem.

have you checked to be sure each sensor is working? you can do it with a helper, have a good distance clear behind you , then just put it in reverse, foot on the brake, and have some one wave there hand in front of each sensor by leaning over and doing each one individually, you should hear the system beep as each sensor is tested. if one of them does not beeo then that's the problem, there are more test's but this is one easy way to check.

Hmm that's a good idea. I had my son walk back there but leaning over and putting his hand on each one is exactly what I need to do. Thanks
