Component description
| Component part | Description |
| Generator (IC regulator) | The IC regulator controls the power generation voltage
by the target
power generation voltage based on the received PWM command
signal.
When there is no PWM command signal, the generator performs the normal power generation according to the characteristic of the IC regulator. |
| IPDM E/R | 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. |
| ECM | 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. |
| Battery current sensor | The battery current sensor is located on the negative battery cable terminal. The battery current sensor detects the charging/discharging current of the battery and sends a voltage signal to the ECM according to the current value detected. |
| 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:
В·Excessive voltage is produced.
В·No voltage is produced. |

Diagnosis procedure
1.Check connector
Turn the ignition switch off.
Disconnect the battery cable from the negative terminal.
Check the terminals and connectors of the data link connector for
damage, bend and loose connection
(connector side and harness side).
Is the inspection resul ...
