1.
PERFORM THE SELF-DIAGNOSIS OF LI-ION BATTERY CONTROLLER
With CONSULT
1. Select “Self Diagnostic Result” of “HV BAT”.
2. Check to see if “P33EB” is detected simultaneously with “P33E2”.
Is P33EB detected?
YES
>> Perform diagnosis on the detected “P33EB”. Refer to
EVB-154, "Diagnosis Procedure"
.
NO
>> GO TO 2.
2.
CHECK BATTERY TEMPERATURE SENSOR
With CONSULT
Using FREEZE FRAME DATA (FFD), check the values of three temperature sensors when DTC is detected.
Is there temperature increase?
Temperature increase is seen>>Replace Li-ion battery. Refer to
EVB-201, "LI-ION BATTERY CONTROL-
LER : Removal and Installation"
.
Temperature increase is not seen>>Replace battery temperature sensors. Refer to
