DESCRIPTION:

DTC CEM-DD21 may be set because of faulty communication between the Alternator and CEM due to the installation of extra LIN wiring for the
upcoming BLIS (Blind Spot Information System). Customers may also report an intermittent DIM message "POWER SYSTEM SERVICE
REQUIRED" It may be possible that there is a pinched LIN-bus wire from the CEM to the BLIS-system between A-pillar body and the dashboard
assembly on the left side. See details below under "SERVICE".
