U1003 is a communication fault on the CAN network. It's not specific as the CAN network interconnects with lots of systems.

So, will it give an esp warning and stop because of this error?

It depends entirely on what the issue is. The CAN networks connect lots of systems up. If there is a communication fault along the way then a backup mode kicks in, but there will continue to be faults until the problem is tracked down and resolved.

Normally if there is an issue with a specific system like the ESP, there will be specific codes recorded against this system - like a faulty wheel speed sensor for example. But with general CAN faults that are unspecified, it really needs somebody with knowledge of CAN systems to track it down. You also may have other fault codes recorded, but your diagnostic equipment may not be able to read them, so that is another possibility.
