System Description: Notes

This system consists of the battery sensor, the gauge control module, the MICU, the rear MICU, the alternator, and the PCM.

The battery sensor measures the battery current, voltage, and temperature in all ignition switch positions. This data is used to control the alternator output, the idle speed, and the interior lights. These are the advantages of this system:

• Helps to prevent over-discharge of the battery
• Helps to protect engine cranking amps
• Helps to extend the battery life
• Helps to improve fuel economy
• Helps to alert the customer of the battery condition
