Hi Forum. I'm having problems trying to find the fuse for my parking Assist. I have a 2019 Sierra Truck. I Looked through the Owners Manual and call GMC. Nobody knows what fuse is for my Assist.
Is there anyone who might know ? Please Help..
That's a great question, and it's a common one with modern trucks that have so many complex electronic features. It sounds like you've done all the right things, and it's frustrating when even the manufacturer can't give you a clear answer.
The short answer is that the parking assist system on your 2019 GMC Sierra is not typically powered by a single fuse. It's not like the old days where one fuse controlled one simple circuit. The system is a lot more complex than that.
The parking assist system is controlled by the Body Control Module (BCM) and the Parking Assist Control Module. These modules are integrated into the vehicle's electrical system, and the system itself has several components, including ultrasonic sensors in the front and rear bumpers, a speaker for the chimes, and the control modules themselves.
Because of this complexity, the parking assist system is often tied into a larger circuit that controls a lot of other features. For example, it might share a fuse with other safety systems or driver-assist features. So, if your parking assist is not working and you have no other issues, it's very unlikely that it's a blown fuse. If the fuse were blown, you would likely have problems with a lot of other features as well.
The more likely culprits for your parking assist issue are a bad sensor, a wiring issue, or a problem with the control module. A bad sensor is the most common cause. A sensor can be damaged by a small bump or can just fail on its own.
Your best bet is to get a proper diagnostic scan from a professional. A standard OBD-II scanner will not be able to read the codes for the parking assist system. You need a scanner that can access the body control module, which will tell you if a specific sensor is malfunctioning.
I know you were looking for an easy fuse fix, but in this case, it's probably not a fuse. A proper diagnosis is the only way to find out what's really going on with your truck.
