The point of this post was not to start an argument. It was to provide useful information to anyone troubleshooting problems with the forward collision system. The way the system indicates problems is counter-intuitive enough that a TSB was created to specifically address it. MC-10251704-9999.pdf https://share.google/g9jqt8GJHeHxhempF

This is meant to be informational and hopefully a time saver for some. I had a 2022 Silverado 1500 and currently own a 2025. In both of those vehicles I have always set "Automatic Emergency Braking" and "Front Pedestrian Braking" to "Alert" (instead of "Alert and Brake" or "Off"). These settings never caused the forward collision warning light to illuminate, until some point in the last couple months (possibly due to a software update?). Now having braking turned off on either of these settings causes the light to be illuminated all the time. I wasted a lot of time trying to figure out why the light was constantly illuminated, not knowing the display logic had changed. The only way to clear the amber light is to have both forward collision modes set to "Alert and Brake." I assume this was done out of some liability concern, but it is frustrating that selecting a normal operating mode (Alert) causes the fault indicator to be illuminated all the time, preventing the system from indicating whether an actual fault is present. I hope this helps anyone looking into the same issue.

@kickass audio, everything you said matches the experience I've had so far. You can definitely work around it if you know exactly how it works. I'd love to find a way to simplify it for people who aren't experts in defeating GM power assist technology (like anybody but me trying to open the tailgate and not damage it).

2025 Silverado 1500 High Country with power tailgate (non multi flex). Looking for a way to delete the power raise/lower feature and have the tailgate operate in the same way it would on a lower trim model without the power actuator. It seems like it should be possible because in some situations you can raise and lower it without the actuator assist and it feels just like the normal manual tailgate. I don't really have a use for this feature, and what I'm trying to be able to do is open the tailgate just a few inches to access the tonneau cover latch in situations where the tailgate can't open all the way (backed in against a fence, bike hitch rack installed). You can press the tailgate button a second time to stop the motion, but sometimes the actuator will resume if you subsequently lower the tailgate a little bit. It's already gone rogue on me once and gotten a pretty good scratch against a bike pedal. The only other way I've found to stop it is to block its motion, but that can't be good for the actuator in the long term. Does anyone know any kind of button-pushing cheat code to disable it? I tried unplugging the harness from the actuator, but somehow the actuator is tied into the logic for the latch. Having the actuator unplugged prevents the tailgate from unlatching and opening. Unless there's an easier way, it shouldn't be too hard to install a switch that would interrupt power to actuator motor, essentially allowing you to toggle the feature on and off. Does anyone know where to find a wiring diagram for the tailgate harnesses? Any ideas are appreciated. Thanks for the help.
