ID1=Internal temperature too high (ventilation/power module), ID2=Gun line temperature too high (aging, sensor, or current setting).
Common causes
Ambient temperature too high (ID1)Poor ventilation (ID1)Fan malfunction (ID1)Charging gun aging or wear (ID2)Temperature sensor fault (ID2)
What to check
STEP 1
ID1: Check ventilation, check for direct sunlight, check fan is functioning normally. ID2: Check charging gun head is plugged in correctly and check for aging or wear
STEP 2
ID1: Replace fan if abnormal. ID2: Check temperature sensor and charging current settings
