2008 Z71 Tahoe "Service Park Assist"
I recently bought a 2008 z71 tahoe. On the back bumper one of the parking sensors had been knocked out. So every time I start the car the "Service Park Assist" light on the dash lights up. And I cannot turn off the park assist with manual button. That little button is always lit and just flashes when I press it. So I ordered a new sensor and installed it… But that still didn't fix it… SO then I ordered a whole new wiring harness for it and installed that… Still doesn't work! What else could it be?????
Also I have a trailer hitch locked in that was in the hitch when I got the Tahoe so I don't have the key to take it off. But… I have read that if it had to do with the hitch, then it would say "Park Assist Blocked" not "Service Park Assist." Any help is appreciated! Thanks!

I just reviewed the park assist system for your vehicle. You are correct; it will display "park assist off" if a trailer hitch is install and "service park assist" for a fault in the system.
codes will be set in the object alarm module. retrieve these fault codes and post them here. these codes can only be read with a full function scan tool

I am in a similar situation. I have a 2009 Suburban LT I replaced the rear sensors, (yes, all 4, I did not want to have 3 reds and the new black, so yes all 4 so they matched.) I also replaced the factory harness as when removing the old sensors the harness disintegrated. (I would like to call it corrosion, anyone disagree?)
Driving forward I get the "service park assist" message at about 8-10 MPH. I clear it to see my odometer, and next time I slow to a stop and start up again it blinks back on with "service park assist"
The funny thing is - when I get home and back into my driveway, when I start to get close to the garage, I get a yellow LED in the rear pillar indicator. I go a few more inches and I get 2 yellow LEDs. I put it in park, put on the park brake and done.
So why does it function in reverse, but send me the "Service park assist" error in while in "Drive"? I don't have a scan tool that can read the specific fault codes. Any suggestions?
