I have a 2010 1500 Sport. My park assist is off and I can not turn on with switch on dash. I go to set-up on EVIC and I can not switch it sound or sound with warning. I have replaced harness and all four sensors on rear bumper. Anything else I should be looking at?

 

Do you see the options in the EVIC you're just unable to select them, or does the option not even appear in the EVIC? Has it ever worked since you owned the truck? Do you have access to a professional grade scan tool that can access the park assist system?

option appears in EVIC but I am unable to change from off position, It has been in alarm since truck purchased, I have replaced all four sensors and wiring harness at bumper. I don't have a scan tool that will
access the park assist.
