DESCRIPTIONS OF MONITOR METHODS <DTC P0A9C - P1ED0: BATT. TEMP. sensor rationality>
- After the vehicle is parked, each temperature is expected to become close to the average battery temperature. Average battery temperature is the average of all 50 sensors.
- Each temperature sensor signal is compared to the average battery temperature after 1 hour soak.
MONITOR EXECUTION <DTC P0A9C - P1ED0>
MONITOR EXECUTION <DTC P0A9D - P1E88, P0A9E - P1E40>
MONITOR EXECUTION CONDITIONS (Other monitor and Sensor)
Other Monitor (There is no temporary DTC set in memory for the item monitored below)
- Main drive lithium-ion battery cell voltage monitor
- Battery CAN monitor
Sensor (The sensor below is determined to be normal)
DTC SET CONDITIONS
Logic Flow Chart <DTC P0A9C - P1ED0: BATT. TEMP. sensor rationality>
Check Conditions
- battery management unit (BMU) power supply voltage is 8 volts to 16 volts.
- Time after above conditions satisfy is less than 2 seconds.
- The soaking time is more than 3,600 seconds.
- The main drive lithium-ion battery temperature is --30°C (-22°F) to 60°C (140°F).
Judgment Criterion
- The absolute value of the difference between the value of average main drive lithium-ion battery temperature and the value of the main drive lithium-ion battery module temperature changes to 13°C (55°F) or more and the state continues for 0.32 seconds.
Logic Flow Chart <DTC P0A9D - P1E88: BATT. TEMP. sensor short, DTC P0A9E - P1E40: BATT. TEMP. sensor open>
Check Conditions
- battery management unit (BMU) power supply voltage is 8 volts to 16 volts.
- Time after above conditions satisfy is more than 2 seconds.
Judgment Criterion <DTC P0A9D - P1E88>
Change of the main drive lithium-ion battery temperature sensor voltage is less than 0.12 volt [more than 125°C (257°F)] for 2 seconds.
Judgment Criterion <DTC P0A9E - P1E40>
Change of the main drive lithium-ion battery temperature sensor voltage is more than 3.97 volts [less than -62°C (-80°F)] for 2 seconds.

FAIL-SAFE AND BACKUP FUNCTION
|
|
|
- The module (Battery cell, cell monitoring unit (CMU) and module temperature sensor) in the main drive lithium-ion battery is failed.
|
|
|
STEP 1. Test the OBD-II drive cycle.
|
|
|
(1)Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle - Pattern 3 . <DTC P0A9C - P1ED0>
|
|
|
(2)Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle - Pattern 1 . <DTC P0A9D - P1E88, P0A9E - P1E40>
|
|
|
(3)Check if the DTC is set.
|
|
|
 Replace the main drive lithium-ion battery (Refer to ) or CMU (Refer to ). Then, go to Step 2.
|
|
|
|
|
|
 Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
|
|
|
|
|
|
STEP 2. Test the OBD-II drive cycle.
|
|
|
(1)Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle - Pattern 3 . <DTC P0A9C - P1ED0>
|
|
|
(2)Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle - Pattern 1 . <DTC P0A9D - P1E88, P0A9E - P1E40>
|
|
|
(3)Check if the DTC is set.
|
|
|
Retry the troubleshooting.
|
|
|
|
|
|
The procedure is complete.
