Constant beeping when driving & reverse , the beeping only stops when stopped at a light or in parked
it sounds like an open door alert with the key still in the ignition ding, ding, ding.

First question - does the vehicle have parking assist / backup sensors?

Check the harness connection at the module itself and at the junction plate under the right rear quarter panel
If the connections are good then it's possible a faulty module.

If this is in code check mode then I would check the wiring for possible pinch points. If the wiring is good, it's possibly a bad module (also check the connection at the module).
