Charging System Messages: Notes

The DIC displays a charging system message the when the following occurs:

• The engine control module (ECM ) detects that the generator output is less than 11 volts or greater than 16 volts. The DIC receives a message from the ECM requesting illumination of the charge indicator / charging system warning message.
• The IPC determines that the system voltage is less than 11 volts or greater than 16 volts. The IPC receives a message from the body control module (BCM) indicating the system voltage.
