Reason for change
Reason for block
Complaint:
• Charging inoperative
• Charging abort
• Fault messages (flash codes) on charging cable box (ICCU)
• Fault messages (flash codes) on charging socket on vehicle
• Question/problems associated with charging process
Cause:
In principle, faults during the charging process and charging abortions can have different reasons. These include:
• Infrastructure
• Charging cable with box (ICCU)
• Charging socket
• On-board charger (OBL)
• HV battery or vehicle control (internal)
For an exact fault analysis and fault rectification please note the points raised in the Remedy chapter with attachments in the TIPS document.
In each instance, it is essential that the customer complaint and the basic conditions are asked about at the
customer's (in particular, which charging mode/charging cable/charger was used) and the customer's charging infrastructure should also be examined.
Remedy:
A) A flash code with red LED on the charging cable box (ICCU) is shown
After inserting the charging cable a self-test is run first. If, after this, one of the two upper LEDs (AC LED and/or CCICLED) lights up in red or if they flash on and off, a malfunction is present.
=> Please use Attachments A1+A2 in this TIPS document to help with interpretation of the possible reasons for the
charging fault and die flash codes.
=> Rectify the fault in accordance with the details given in "Remedy/recommended actions" in the attachment.

B) A flash code on the vehicle's charging socket is displayed.
The charging socket on the vehicle always indicates each operating condition (Charging, vehicle unlocked, fault etc.)
through two LEDs.
=> Please use Attachments B1+B2 in this TIPS document to interpret the reason for the LED display
=> If a fault is found, rectify it in accordance with the details given in "Possible remedies/recommended actions" in the
attachment.
C) Fault without flash code or remedies under A+B would not serve any purpose
