2016 Ford Explorer Check Brake System Warning light will not go away- Unknown Cause or repair

The brake light came on while driving this 2016 Ford Explorer and my mechanic could not find or resolve the issue. The vehicle runs perfectly fine and the brakes all work perfectly fine. I do not have any ABS lights or trash control issues. It will still go into four-wheel-drive and decent also works. I read some articles and found that it could be the emergency brake hung up, but I disconnected the two wire connector and it did nothing. So I jumped the wires and it did nothing. Then thought it may be the brake reservoir fluid level sensor going bad because I have seen that they go bad and Ford had them backordered. I found a dealership that had one, but this also did not fix the problem. We have it on a computer and it is not telling us anything about a brake error in the diagnostics Please leave a comment below if you have run into this issue or found a resolution. Here is the link to the part that I tried to replace Brake Fluid Level Switch - Ford (CB5Z-2C251-A) https://ford.autonationparts.com/part...
