When we think about repairing a car, the most time-consuming and challenging job is to repair wiring or car electronics. Understanding wiring is complicated because hundreds of wires in different colours are connected to the system, from car Sensors to the ECU and ECU's other modules and actuators. In simple, car door modules to car exhaust modules are connected through a network called CAN-Bus System. The car starts disturbing the system if any wire is missing or disconnected in the Can-Bus system. Eventually, the central controllers, Engine Control Module, Body Control Module and Stability Control Unit pass the messages to Immobiliser. Immobiliser works like a Police, and it can stop the car immediately when it receives the final request of the ECU.
Diagnosing Car CAN Bus Faults
Car CAN-Bus (Controllers Area Network) is the most sensitive area; when you have a Car Diagnostic Test and receive "U Codes", there is a problem in the CAN Bus, or any controller is not functioning correctly. Car CAN Bus is comprised of two twisted wires, and these wires can have different colours.

Just one rusty connector or any damaged wire in the Can-Bus system can disturb the entire Electronic-Control-System. This fault creates a gap in the communication network that supplies information to the ECU and other car modules and the sensors, and this is the fault we call "Limp Mode." "Home Mode." or "Workshop Mode.".
Most technicians avoid repairing CAN Bus faults as it is a difficult job. They advise the customers to send their ECUs to ECU testing labs. It is a waste of money and time because before sending the car ECU to test, it is easy to check the signals from the ECU terminals using an oscilloscope.
