Model Description
i4 Gran Coupe Battery Electric Vehicle (BEV)
i5 Sedan (BEV)
i7 Sedan (BEV)
750e xDrive Sedan Plug-in Hybrid Electric Vehicle (PHEV)
iX Sports Activity Vehicle (SAV)
BMW XM Sports Activity Vehicle (PHEV)
X5 Sports Activity Vehicle (PHEV)

SITUATION
Gen 5 BEV/PHEV vehicles may set the Combined Charging Unit (CCU) in programming abort due to no
communication to the HV charge socket electronics.

CAUSE
The CCU checks for the coding file for the charging socket via the CCU CAN. When the wrong charge
socket is installed or there is a communication breakdown between the CCU and the charge socket
electronics, the CCU will “drop” the coding file for the charge socket.
This will set the faults listed below for “hardware inconsistent” and put the CCU in “programming abort,”
whereby fault S0768 Programming Abort will be stored along with one or more of the faults listed below.
0321A9 - High voltage charging socket: hardware inconsistent
0321AA - High voltage charging socket: software inconsistent
CCU_P1 S0768 Programming abort: Combined charging unit
The following DTCs point to a missing connection:
D7975D - Message (status of charging socket flap) missing, receiver CCU, transmitter high-voltage charging
socket
D79763 - Message (status display of charging process status) missing, receiver CCU, transmitter highvoltage charging socket
D79769 - Message (status of charging plug lock) missing, receiver CCU, transmitter high-voltage charging
socket
D7976C - Message (AC charging, temperature of high-voltage charging socket) missing, receiver CCU,
transmitter high-voltage charging socket
D7976F - Message (DC charging, temperature of high-voltage charging socket) missing, receiver CCU,
transmitter high-voltage charging socket rear
D797C3 - Message (status of high-voltage charging socket) missing, receiver CCU, transmitter high-voltage
charging socket.

61 03 24_BEV/PHEV CCU - PROGRAMMING ABORT LINKED TO THE HV CHARGE SOCKET

CORRECTION
Caution: Do not program a CCU that has fault S0768 Programming Abort stored!
If the vehicle is programmed with the fault “S0768 Programming Abort,” the CCU will go offline.
An indication of this is that the CCU will appear “Blue” in the ISTA module tree. Instead, follow the
procedure below.
Information is found in Repair Instruction 61 00… “Observe safety instructions when handling
electric vehicles”.
Additional Information:
Scheduled Maintenance, or Quality Certification 1 (Pre-Delivery Inspection) on Electric or Hybrid
vehicles does not require HV technical training.
Prior to disconnecting, or the removal of any HV component, the HV system needs to be disabled
and secured (by means of the HV Disconnect Switch) by a properly trained technician, who has a
minimum HV Qualification level after completing the Technical Training Course ST1824 (Alternative
Drive Part 1). Once the vehicle’s HV system is disabled (the “Blitz” - lightning bolt icon displayed in
instrument cluster, see below), a technician without HV Certification may remove a HV component
(e.g., EH Heater, EKK Compressor, EME Control Unit, et.), except for the High Voltage Battery.

High Voltage Battery removal and rework can be performed ONLY by a HV Specialist Technician
(certified by the Technical Training Course ST1825 – Alternative Drive Part 2), AND with a HV Battery
Certification level corresponding to a specific Electric or Hybrid vehicle (e.g., to repair GEN4 battery
of G05 PHEV, certification from Technical Training Course “ST2006 – SP44 HV Battery” is required).
Therefore, to perform this SIB 61 24 22 a GEN5 battery Certification is required from Technical
Training Course “ST2205 Generation 5 High-voltage” class).
If the fault codes mentioned above are stored regarding the charge socket and/or communication, and after
you have tested everything below, please submit a TSARA case titled:
“Charge Socket Communication/Programming Abort” for assistance

PROCEDURE
Follow the test plans for the following faults first!
0321A9 - High voltage charging socket: hardware inconsistent
0321AA – High voltage charging socket: software inconsistent
Do not attempt to program the car until the communication is reestablished with the charge socket,
or the CCU will be offline as mentioned above.
Once the communication is reestablished and the faults can be cleared, the CCU will be able to be
recovered.
Checks and possible causes:

The charging socket electronics may be defective, not responding to the CCU request
The charging socket is the wrong part number for this vehicle

The replacement charging socket may require a retrofit 8WN depending on the production date
(*BEV only)
Check the charging socket fuse (make sure it is not blown)
Check 12V power supply and ground connections at the charging socket
Check the harness between the CCU and the charge socket
The CCU CAN communication may be down or faulty
The PINs at the harness 12v connectors CCU or Charge socket
The CCU power supply, fuse, grounds
Internal fault of the CCU
*With regards to GEN 5 BEV vehiclesStarting with production 03/2023, a unified charging socket was introduced for all variants.
In case of a HV charging socket replacement on a Gen 5 BEV vehicle, the “Conversion charging
socket with alternative microprocessor (SA 8WN)” may be required.
This hint is only found in electronic parts catalogue (ETK) under the required part.
Attention! For vehicles without SA 8WNThe SA 8WN must be installed in the “Vehicle Order.” Use the retrofit "Conversion to charging
socket with alternative microprocessor" button via ISTA.
With option 8WN, the matching coding file (SWFK) for the new generation charging socket will be computed
and stored in the CCU.
NoteThe ISTA test plans for the stored faults will ask if the charging socket was replaced.
If the vehicle is a BEV, ISTA will check if it requires the SA 8WN conversion for the charging socket
installed.

CLAIM INFORMATION
This Service Information Bulletin provides technical, diagnosis, and repair-related information.
Damage and/or issues caused by outside influences are not covered under the BMW limited warranties.
