• IPDM E/R sends alternator voltage request signal to ECM via CAN communication.
• ECM transmits alternator voltage request signal to alternator via LIN communication.
• Control module inside alternator controls the power generation voltage based on the received alternator volt-

age request signal.

• Alternator includes a self-diagnosis function and transmits the diagnosis result to ECM via LIN communica-

tion when detecting any malfunction.
