Generator Battery Temperature Sensors
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
Each battery module has a separate temperature sensor, or thermistor. These sensors are serviced as a pair (one pair for each battery cassette). The battery cassette must be removed from the vehicle in order to access the thermistors. These sensors receive power and provide a battery temperature feedback signal to the generator battery disconnect control module through the generator battery temperature sensor wiring harness.
