DESCRIPTIONS OF MONITOR METHODS
  • Battery deterioration can be determined based on cell internal resistance.
  • Cell internal resistance is calculated from cell voltage variation and cell current variation.
 
 
MONITOR EXECUTION
  • Continuous
 
 
MONITOR EXECUTION CONDITIONS (Other monitor and Sensor)
Other Monitor (There is no temporary DTC stored in memory for the item monitored below)
  • Battery CAN monitor
Sensor (The sensor below is determined to be normal)
  • Not applicable
 
 
DTC SET CONDITIONS
Logic Flow Chart
Check Conditions
  • BMU (SUB) power supply voltage is 8 volts to 16 volts.
  • Time after above conditions satisfy is more than 2 seconds.
  • Main drive lithium-ion battery current is more than 30 amperes.
  • The main drive lithium-ion battery minimum temperature is more than 21°F (-6°C).
  • Main drive lithium-ion battery energy level is 20 % to 90 %.
Judgment Criterion
  • The state with the cell internal resistance being the specified value or more for 1 second without interruption is detected 10 times.
 
 
OBD-II DRIVE CYCLE PATTERN
  • Refer to OBD-II Drive Cycle - Pattern 5 .
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • Not available
 
 
PROBABLE CAUSE
  • The module (battery cell, CMU) in the main drive lithium-ion battery is failed. (Refer to )
 
 
 
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 5 .
(2) Check the DTC.
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 5 .
(2) Check the DTC.
Is the DTC set?
Retry the troubleshooting.
The inspection is complete.
