Park Assist Wiring Schematic

[Keagan]

Anyone have or know where I can get the wiring diagram for my front park assist? Initially I thought I had this figured out, hooked it up to a friends scanner and he said the 12v was missing, he also found water in the harness. Drained out as much and sprayed electric cleaner and let it sit. It worked for a week or so and it began to be intermittent. Last he checked, all sensors were good and clean. Any diagrams?

 

P.S. The park assist light on the switch bank does come on when you turn the ignition to on without start but then goes away while the lane departure one stays light until I start the truck.

 

Thanks!

Go to GMUpfitter.com, download the Electrical Schematics for our trucks. It's abkj 1688 pages for 2016. Then search for Park Assist. There is a park assist module that's mounted behind the passenger rear seat. Front and rear sensors go to/from the module.

Is there anywhere to find a more in depth schematic? I am trying to bypass the harness and go without the sensors. I want to know if there is any way for me to just replace the harness with a dummy wire or something to get rid of the service park assist notification.
