Typical Scan Tool Data
Circuit/System Description
The drive motor generator battery has four hybrid battery temperature sensors. The hybrid battery temperature sensors are located on the top of the
hybrid batteries. The temperature sensor is a variable resistor that measures the temperature of the hybrid batteries. The control module supplies 5 V
to the signal circuit and a ground for the low reference circuit. The hybrid battery temperature sensor resistance changes with battery temperature.
The lower the temperature, the higher the resistance of the sensor. The higher the temperature, the lower the resistance of the sensor. The drive
motor generator battery control module (BECM) uses the battery temperature sensors to determine the hybrid battery temperature to control the
battery cooling fan operation.
Conditions for Running the DTC
* The ignition is ON.
* The 12 V battery voltage is 9-18 V.
Conditions for Setting the DTC
P0A9C, P0AC6, P0ACB, and P0AE9
The hybrid battery temperature sensor is in normal operating range, but is 15锟斤拷C (59锟斤拷F) different from the other 3 sensors.
P0A9D, P0AC7, P0ACC, and P0AEA
The hybrid battery temperature is greater than 95锟斤拷C (203锟斤拷F) and one other temperature sensor is less than 70锟斤拷C (158锟斤拷F).
P0A9E, P0AC8, P0ACD, and P0AEB
The hybrid battery temperature is less than -40锟斤拷C (-40锟斤拷F).
Action Taken When the DTC Sets
* DTCs P0A9C, P0A9D, P0A9E, P0AC6, P0AC7, P0AC8, P0ACB, P0ACC, P0ACD, P0AE9, P0AEB, and P0AEA are type B DTCs.
