Please help! How can I stop this constant beep sound manually without an advanced scanner?

What another engineer did was replace the master cylinder and servo because of no brake when the pedal is depressed with a new but converted type. The brakes are okay now according to the client.
However, the sound is still emanating. They were unable to stop the beeping sound.

I don't know either how to fix this noise/beep for the client. Please guide me on how to rectify and fix the problem.

Hi David,

I would do a system reboot, please follow this guide:

If this doesn't work, we will need to scan the car for codes. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:

Please go over these guides and get back to us.

Thanks for the guide! However, the beep problem wasn't fixed. If I get or purchase a bidirectional scanner I'll get back to the client.

Now thinking about it, I would check the engine oil level. Please let me know.
