U113E CHRYSLER Description
The Intelligent Battery Sensor (IBS) is mounted in-line with the negative Battery Cable. The IBS monitors the Battery state of charge and current draw. The IBS also has a built-in thermistor that calculates the Battery temperature. This information is reported through a Local Interconnect Network (LIN) BUS circuit to the Body Control Module (BCM). The BCM broadcasts the information to the Powertrain Control Module (PCM) over the Controller Area Network (CAN) BUS. The Diagnostic Trouble Code (DTC) sets when the BCM does not receive LIN Bus messages from the Intelligent Battery Sensor (IBS) for greater than 180 milliseconds.
