Turning Off Parking Assist Permanently

[dugstruble]

Anyone know how to turn off parking assist permanently? I bought a grill guard and had it installed. Did not know it was going to interfere with parking assist. Not really all that important, as I usually back in when parking and use the camera. When I go into the infotament system and turn it off there, you would think it would stay turned off. Nope. When I start the truck back on it comes on again. I looked through the fuse diagrams to see if there was a dedicated fuse. Found nothing. If I detach the sensors in the front, I get error messages. The dealer had no clue either. Any ideas?

May need to find out what the resistance is and put a resistor in the harness to fool the BCM into thinking the sensors are still plugged in.

pull the fuse?

No and no. They're ultrasonic so a resistor won't do it. Pulling a fuse will just get another warning. Not sure if there is a solution right now for this.

Probably need to have the BCM tuned to have it be off by default. Then you could still turn it on if you wanted by pushing the button on the center stack. There is a member that does BCM tuning, but I always forget his name....

GTPprix (Chris) is who does BCM programming.

Another thought is some guys who have the Bull Bars drilled holes and mounted the sensors on the bar.

This may help, but it is not directly talking about the new 2014 half tons trucks. Read the section about "removing rear park assist". Here's a link and an abstract from the article:

http://sandyblogs.com/techlink/?m=201404

 

1. On all model years, disable the Rear Park Assist Module (in most cases, by removing the OBS DET fuse 20, 10 amp, from the left I/P fuse block).

2. For 2007-2009 models, contact the Techline Customer Support Center to obtain an Instrument Panel Cluster (IPC) calibration to disable the option.

3. For 2010-2014 models, remove power to the IPC for several minutes by disconnecting the battery. When power is reconnected, the IPC will not see the Park Assist Module on the low speed data buss (because it was disabled in Step 1) and reconfigure the IPC without Rear Park Assist. After this is complete, there will be not any Rear Park Assist warning messages displayed.

What does IPC stand for? I am not looking to remove a warning. I am just looking to permanently turn it off. Someone mentioned BCM programming. I am not even sure what that is or if there is someone local to me that can do that. It just would be nice if the infotainment system would remember by setting when I turn it off in the menu after my truck restarts like it remembers my other settings. It doesn't make sense why it does't retain that info.

Pretty sure that procedure only applies to rear park assist on previous generation HD trucks. The procedure exists for trucks that were bought with park assist and then had the bumper removed to accommodate a utility body or similar.

So it sounds like I'm SOL for my 2014 Silverado. lol I just wish the infotainment system settings would stick with the park assist settings. Good grief!

I just installed a bull bar on my 2016 Sierra and have the same issue. Any updates that you’ve found? Thanks!
