General Information
The control area network (CAN) is monitored and controlled by the central electronic module (CEM). When the central electronic module (CEM) detects a fault in the controller area network (CAN) a diagnostic trouble code (DTC) is stored in the central electronic module (CEM). There are different types of diagnostic trouble codes (DTCs) depending on the type of fault.
Fault types which are processed are:
- Electrical faults
- No communication from a control module
- Faulty communication.
NOTE:
To troubleshoot respective CAN-net, see troubleshooting for CAN-related diagnostic trouble codes for Central electronic module (CEM). For example, choose any of CEM-DF01 - DF17 depending on CAN-net.
