Component

Function

1.

Generator

Refer to Generator .

2

IPDM E/R (Intelligent Power Distribution Module Engine Room)

The IPDM E/R converts the received power generation command value into a pulse width modulated (PWM) command signal and sends it to the IC regulator.

Refer to Component Location for detailed component location.

3.

ECM (Engine Control Module)

• The battery current sensor detects the charging/discharging current of the battery. The ECM judges the battery condition based on this signal.
• The ECM judges whether to request more output via the power generation voltage variable control according to the battery condition.
• When performing the power generation voltage variable control, the ECM calculates the target power generation voltage according to the battery condition and sends the calculated value as the power generation command value to the IPDM E/R.

4.

Battery current sensor

Refer to Battery Current Sensor .

5.

Combination meter (charge warning lamp)

The IC regulator warning function activates to illuminate the charge warning lamp if any of the following symptoms occur while generator is operating:

• Excessive voltage is produced.
• No voltage is produced.
