Error Management In the Controller Area Network (CAN): General

The CAN network is monitored by the central electronic module (CEM). When the central electronic module (CEM) detects a fault in the CAN network, a diagnostic trouble code (DTC) is stored in the central electronic module (CEM). There are various types of diagnostic trouble code (DTC), depending on the type of fault.

Types of error which are handled are: 

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