CAN bus is not a module but a way of communicating between various components. In other ways, it is the wires. But unlike the typical electrical wires, CAN bus can transmit multiple signals. These wires are all over the car. 

What you need to look for is the modules. It seems that the ESP module is not communicating. My guess is that it is either damaged by water or has broken contacts. 

Locate the ESP module in your car, which I believe is in the engine bay. Remove it. 

Open it. Check for water. If no water damage is visible, look very carefully at the pins that connect the motherboard to the plug/wire harness. 

Let me know what you find out.
