The Central Electronic Module (CEM) both transmits and receives information via a standardized serial communication method - LIN (Local Interconnect Network).

Unplug the connector from Start control module (SCU).

Click on the VCT2000 (Volvo Scan Tool) symbol.

Establish whether relevant LIN diagnostic trouble codes (DTCs) are stored in the control module.

These should be remedied first.
