Diagnosis Procedure

INFOID:0000000010121149

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 

EVB-190, "BATTERY

PACK UPPER CASE : Exploded View"
