3) Condition for Running Diagnostic
During charging
4) Condition for Setting the Fault Code
Overcharge or abnormal cell voltage rise(Highest cell voltaeg > 4.2V)
5) Condition for Clearing the Fault Code
Operate the machine to discharge to the Highest cell voltage ≤ 4.15V
6) Check List
Step Inspection Reference value YES NO
1 P3A01 is detected on service tool? CV_HI > 4.2V Step 2
2
Disconnect the battery charger.
Operate the machine to discharge cell voltage in less than 1 hr. Check the highest cell voltage(CV_HI) via service tool.
Is P3A01 disappeared?
CV_HI ≤ 4.15V Problem Solved
