RAM 2500 Truck 2WD V8-5.9L VIN Z (1997)
Battery Temperature Sensor: Description and Operation
SYSTEM OPERATION
The battery temperature sensor is used to determine the battery temperature and control battery charging rate. This temperature data, along with
data from monitored line voltage, is used by the PCM to vary the battery charging rate. System voltage will be higher at colder temperatures and is
gradually reduced at warmer temperatures.
CIRCUIT OPERATION
The Powertrain Control Module (PCM) determines battery temperature on circuit K118. Circuit K118 connects the PCM to the battery
temperature sensor. Circuit K4 provides ground for the sensor. Circuit K118 connects to cavity C15 of the PCM. Circuit K4 connects to cavity A4.
