SYSTEM DESCRIPTION
• 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.
• Charge warning lamp turns ON when any of the following symptom occurs while ignition switch is ON:
- Excessive voltage is produced.
- No voltage is produced.
- High voltage is detected from battery positive terminal.
