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)
M5 Sedan
M5 Touring

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.

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.
Warning! Note: Safety related information is found in Repair Instruction 61 00… “Observe safety
instructions when handling electric vehicles”.
The high-voltage system operates based on hazardous, electrical voltage and high currents. Danger to life
due to electric shock!
Therefore, all work on the high-voltage system may only be carried out by specially trained and technically
experienced personnel. When working near high-voltage components (labelled accordingly by signs and/or
an orange coating), disconnect the high-voltage system to protect the high-voltage components from
damage.
For more information regarding the necessary Technical Training courses and High-voltage
qualifications that certify technicians to perform the various high-voltage operations on Hybrid and
Electric BMW vehicles, please refer to the BMW Technical Training bulletin
SI B03 01 25 - HIGH VOLTAGE TRAINING QUALIFICATIONS - APPLIED GUIDELINES FOR WORKING
ON BMW ELECTRIFIED VEHICLES.
If the fault codes mentioned above are stored regarding the charge socket and/or communication, and after
you have tested everything below, you still need assistance, please submit a TSARA case titled:
“Charge Socket Communication/Programming Abort”

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 vehiclesUPDATE
There are two versions of high voltage charging socket for Gen 5 BEVs, the early version is being
discontinued and replaced with the new part number with more robust electronics.
The HV charging socket part number replacement may or may not require the “Conversion charging
socket with alternative microprocessor (SA 8WN)” installed in the vehicle order.
This hint is found in electronic parts catalogue (ETK or AIR) under the required part and must be
noted when ordering the part.

Attention!
The SA 8WN may or may not have to be installed in the “Vehicle Order.” This depends on the
charging socket part number and if the vehicles came with SA 8WN as Original Equipment.
Use the retrofit "Conversion to charging socket with alternative microprocessor" button via ISTA to
add or remove the option as required.

The new HV charging Socket must align with the 8WN VO requirement and the CCU coding.
The matching coding file (SWFK) for the new generation charging socket will be computed and stored in the
CCU. This is checked on every start up.
Note:
The ISTA test plans for the stored faults will ask if the charging socket was replaced.
Hint: If the Charging Socket and CCU alignment is not correct, the CCU will be placed on
programming abort and will appear blue with the fault S0768. ISTA will then not allow further action.
Workaround for recovering the programming abort S0768:

1. Note the part number you want to install and its 8WN requirements
2. Briefly connect the old charging socket 12V connector to regain communication with the CCU
3. Using ISTA add or remove the 8WN conversion as needed.
4. Then install the new part and program and code as usual.
5. If this doesn’t work, submit a TSARA case for further assistance or to recover the CCU with
IRAP

Note: For more information regarding GEN 5 PHEV high voltage charging socket replacement see
SIB61 12 25.
