Charging System Indicators

The IPC illuminates the charge indicator when the following occurs:

• The PCM detects that the generator output is less than 11 volts or greater than 16 volts. The IPC receives a class 2 message from the PCM requesting illumination.
• The IPC determines that the system voltage is less than 11 volts or greater than 16 volts. The IPC receives a class 2 message from the dash integration module (DIM) indicating the system voltage.
• The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.

1. BATTERY NOT CHARGING - 7:  The IPC illuminates the BATTERY NOT CHARGING - 7 indicator in the DIC when the PCM detects a malfunction with the generator output. The IPC receives a class 2 message from the PCM requesting illumination.
2. BATTERY SAVER ACTIVE - 27:  The IPC illuminates the BATTERY SAVER ACTIVE - 27 indicator in the DIC when the Dash Integration Module (DIM) reduces or disables the performance of some vehicle systems in order to reduce the load on the charging system. The IPC receives a class 2 message from the DIM requesting illumination.
3. BATTERY VOLTAGE HIGH - 8:  The IPC illuminates the BATTERY VOLTAGE HIGH - 8 indicator in the DIC when the IPC determines that the system voltage is greater than 16 volts. The IPC receives a class 2 message from the dash integration module (DIM) indicating the system voltage.
4. BATTERY VOLTAGE LOW - 6:  The IPC illuminates the BATTERY VOLTAGE LOW - 6 indicator in the DIC when the IPC determines that the system voltage is less than 11 volts. The IPC receives a class 2 message from the dash integration module (DIM) indicating the system voltage.
5. SERVICE CHARGING SYS - 102:  The IPC illuminates the SERVICE CHARGING SYS - 102 indicator in the DIC when the PCM detects a malfunction with the generator output. The IPC receives a class 2 message from the PCM requesting illumination.
