WC03 - Re-programming Front-end Electronics Control Unit and Rear-end Electronics
Control Unit (Workshop Campaign)
Vehicle Type:
911 Carrera (991)/911 Carrera S (991)
Model Year:
2012
Concerns:
Front-end electronics control unit
Rear-end electronics control unit
Information:
This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles.
New data records for the front-end electronics and rear-end electronics control units are available for the
affected vehicles.
•
Front-end electronics control unit:
If the vehicle key is not inserted completely into the ignition lock and the ignition lock is then turned to the
position “Ignition on”, the ignition lock will be locked after removing the key and the vehicle key can no
longer be inserted into the ignition lock.
To prevent this from happening, the front-end electronics control unit must be re-programmed with an
updated data record.
•
Rear-end electronics control unit:
Due to a software error, there is a possibility that the rear-end electronics control unit will not switch to
energy-saving mode after the vehicle is stopped in the event of specific user behaviour.
This can result in an increased closed-circuit current load and can thus cause the battery to become
discharged.
To prevent this from happening, the rear-end electronics control unit must be re-programmed with an
updated data record.
Action
Required:
Re-program front-end electronics control unit and rear-end electronics control unit.
Information
The total time required for programming and coding is approx. 6-10 minutes, depending on the scope.
Affected
Vehicles:
The VIN(s) can be checked by using PIWIS Vehicle Information link to verify if the campaign affects the
vehicle. This Campaign is scope specific to the VIN! Failure to verify in PIWIS may result in an improper
repair.
Tools:
PIWIS Tester II 9818 with software version 10.400 (or higher) installed.
Battery charger (current rating of at least 40 A).

See Attachment “A”.
Preliminary work
NOTICE
Fault entry in the fault memory and control unit programming aborted due to low voltage.
•
Increased current draw during diagnosis or control unit programming can cause a drop in voltage, which
can result in one or more fault entries and the abnormal termination of the programming process.
⇒
Before starting control unit programming, connect a suitable battery charger with a current rating of at
least 40 A to the vehicle.
NOTICE
Control unit programming will be aborted if the Internet connection is unstable.
•
An unstable Internet connection can interrupt communication between PIWIS Tester II and the vehicle
communication module (VCI). As a result, control unit programming may be aborted.
⇒
During control unit programming, always connect PIWIS Tester II to the vehicle communication module
(VCI) via the USB cable.
NOTICE
Control unit programming will be aborted if the vehicle key is not recognized
•
If the vehicle key is not recognized in vehicles with Porsche Entry & Drive, programming cannot be started
or will be interrupted.
⇒
Switch on the ignition using the original vehicle key. To do this, replace the original vehicle key in the
ignition lock with the plastic key fob if it was previously removed at the start of this procedure.

First connect the positive cable of the charger
to the positive terminal of the battery and then
connect the negative cable of the charger to the
ground point for jump-lead starting ⇒ External
power connection.

2
Switch on ignition using the original vehicle key. For vehicles with "Porsche Entry & Drive", do
this by replacing the control panel in the ignition lock with the original vehicle key if necessary.
3
Move the windshield wiper lever to position 0 (= windshield wipers off) to prevent the windshield
wipers from coming on during programming.
4
PIWIS Tester II 9818 with software version 10.400 (or higher) installed must be connected to the
vehicle communication module (VCI) via the USB cable. Then, connect the communication module
to the vehicle and switch on the PIWIS Tester.
Carrying out control unit programming
Information
The procedure described here is based on the PIWIS Tester II software version 10.400.
The PIWIS Tester instructions take precedence and in the event of a discrepancy, these are the
instructions that must be followed.
A discrepancy may arise with later software versions for example.

Press •>>“ to start the guided programming sequence.
Information
Read and follow the information and instructions on the PIWIS Tester during the guided
programming sequence. Do not interrupt programming and coding.
Programming and coding is performed in several steps:
•
The gateway control unit is first re-coded in preparation for programming.
•
Then, the front-end electronics control unit and the rear-end electronics control unit are also
re-programmed and then automatically re-coded.
•
The gateway control unit is coded again once programming is complete.
The display in the instrument cluster is switched off while the front-end electronics control unit is
being programmed and will remain off during the entire programming procedure.
The message "Ignition key not removed" appears in the multi-function display.
The ignition is still active in the background.
Never switch the ignition off and then on again because if you do, programming will be interrupted and will
then have to be restarted.
The display in the instrument cluster will be switched on again automatically as soon as programming is
complete.
