cautionBefore replacing the ECU, ensure that the communication circuit is normal.
 
 
 
 
MONITOR EXECUTION
  • Continuous
 
 
MONITOR EXECUTION CONDITIONS (Other monitor and Sensor)
Other Monitor (There is no temporary DTC set in memory for the item monitored below)
  • Battery CAN monitor
Sensor (The sensor below is determined to be normal)
  • Main drive lithium-ion battery temperature sensor monitor
 
 
DTC SET CONDITIONS
Logic Flow Chart
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
  • Cell module temperature is 60°C (140°F) or more and less than 125°C (257°F) and the state continues for 1 second.
 
 
OBD-II DRIVE CYCLE PATTERN
  • Refer to OBD-II Drive Cycle - Pattern 1 .
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • Not available
 
 
PROBABLE CAUSES
  • The main drive lithium-ion battery cooling is insufficient with the failed air conditioning control system.
  • Poor cooled main battery due to a defective battery cooling fan.
  • The module (battery cell, CMU) in the main drive lithium-ion battery is failed.
 
 
 
 
DIAGNOSIS
STEP 1. Using scan tool (M.U.T.-IIISE), check whether the other DTC is set.
Check whether DTC P0A82, P0A83 and P0A84 are set at the same time.
Is the DTC set?
Troubleshoot for the relevant DTC (Refer to ).
Go to Step 2.
 
STEP 2. Using scan tool (M.U.T.-IIISE), check whether the other DTC is set.
Is the DTC related to A/C-ECU or A/C compressor assembly system set?
Check A/C-ECU system (Refer to GROUP 55, A/C-ECU - Diagnosis Code Chart , A/C Compressor Assembly - Diagnosis Code Chart ).
Go to Step 3.
 
STEP 3. Using scan tool (M.U.T.-IIISE), check the data list.
Set scan tool (M.U.T.-IIISE) to the data list (Refer to ).
  • Item No.177 - 181: Module temperature 00 - 04
  • Item No.183 - 187: Module temperature 06 - 10
  • Item No.189 - 193: Module temperature 12 - 16
  • Item No.195 - 199: Module temperature 18 - 22
  • Item No.201 - 205: Module temperature 24 - 28
  • Item No.213 - 217: Module temperature 36 - 39
  • Item No.219 - 223: Module temperature 42 - 46
  • Item No.225 - 229: Module temperature 48 - 52
  • Item No.231 - 235: Module temperature 54 -58
  • Item No.237 - 241: Module temperature 60 -64
OK: At ambient temperature (atmospheric temperature) or equivalent (when the vehicle driving and the charge are not performed for a long time)
Is the check result normal?
Go to Step 4.
Remove the battery tray cover (Refer to ). Replace the module corresponding to the diagnostic trouble code being set. Then, assemble the main drive lithium-ion battery assembly (Refer to ). Then go to Step 5.
 
STEP 4. Check the bus bar for looseness.
(1) Remove the battery tray cover (Refer to ).
(2) Check the bus bar around the module of the set diagnostic trouble code for looseness.
Is the check result normal?
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
Repair the looseness of the bus bar or replace it. Then, assemble the main drive lithium-ion battery assembly (Refer to ). Then go to Step 5 .
 
STEP 5. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle - Pattern 1 .
(2) Check if the DTC is set.
Is the DTC set?
Retry the troubleshooting.
The inspection is complete.
