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)
  • Not applicable
 
 
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
  • Change of the battery cell voltage is less than 2.1 volts or more than 4.6 volts for 5 seconds.
 
 
OBD-II DRIVE CYCLE PATTERN
  • Refer to OBD-II Drive Cycle - Pattern 1 .
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • Not available
 
 
PROBABLE CAUSE
  • The module (battery cell and CMU) in the main drive lithium-ion battery is failed.
 
 
 
 
DIAGNOSIS
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 1 .
(2) Check if the DTC is set.
Is the DTC set?
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 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 1 .
(2) Check if the DTC is set.
Is the DTC set?
Retry the troubleshooting.
The inspection is complete.
