Error Management In The Controller Area Network (Can): Overview

The Controller area network (CAN) is monitored and controlled by the central electronic module. When the central electronic module detects a fault in the controller area network a diagnostic trouble code (DTC) is set in the central electronic module. There are different diagnostic trouble codes depending on the type of malfunction detected.

Types of error which are handled are:

• Electrical faults
• No communication from the control module
• Faulty communication.
