I have searched the Forum and found a couple threads on this subject but nothing as to how to go about finding out what is causing the Alert message "Check Backup Aid" or what might be wrong and need troubleshooting. After 14 years, I guess something has died or a connection has wiggled lose.
It looks like there are 2 sensors on the rear bumper. How can these be tested? Anything else back there that needs checked?
