WE18 - Re-programming Control Unit for Porsche Dynamic Chassis Control (PDCC)
(Workshop Campaign)
Important:
CRITICAL WARNING - THIS CAMPAIGN INCLUDES STEPS WHERE SEVERAL CONTROL UNITS IN
THE VEHICLE WILL BE PROGRAMMED WITH THE PIWIS TESTER. IT IS CRITICAL THAT THE VEHICLE
VOLTAGE BE BETWEEN 13.5 VOLTS AND 14.5 VOLTS DURING THIS PROGRAMMING. OTHERWISE, THE
PROGRAMMING COULD FAIL RESULTING IN DAMAGED CONTROL UNITS. CONTROL UNITS DAMAGED BY
INADEQUATE VOLTAGE WILL NOT BE COVERED UNDER WARRANTY. THE TECHNICIAN MUST VERIFY THE
ACTUAL VEHICLE VOLTAGE IN THE INSTRUMENT CLUSTER OR IN THE PIWIS TESTER BEFORE STARTING
THE CAMPAIGN AND ALSO DOCUMENT THE ACTUAL VOLTAGE ON THE REPAIR ORDER. IT IS ALSO
ADVISABLE TO MONITOR THE VEHICLE VOLTAGE DURING THE PROGRAMMING VIA THE INSTRUMENT
CLUSTER. PLEASE REFER TO EQUIPMENT INFORMATION EQ-1105 FOR A LIST OF SUITABLE BATTERY
CHARGERS/POWER SUPPLIES WHICH SHOULD BE USED TO MAINTAIN VEHICLE VOLTAGE.
Model Year:
As of 2012 up to 2015
Model Line:
911 Carrera (991)
Equipment:
Porsche Dynamic Chassis Control (PDCC), I-no. 031/352
Concerns:
Control unit for Porsche Dynamic Chassis Control (PDCC)
Information:
This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. Due to
a software error in the control unit for Porsche Dynamic Chassis Control (PDCC), there is
a possibility that an unauthorized fault code will be stored in the control unit under certain
ambient conditions.
This can cause the error message "PDCC failure" to be displayed in the instrument cluster and the PDCC
function will no longer be available.
Action
Required:
Re-program control unit for Porsche Dynamic Chassis Control (PDCC).
Information
The total time required for programming and coding the control unit is approx. 3 minutes.
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. This campaign affects 3001 vehicles in North America.
Tools:
•
•
9818 - PIWIS Tester II with PIWIS Tester software version 13.800 (or higher) installed
Battery Charger/Power Supply - Suitable for AGM Type batteries, recommended current rating of

See Attachment “B”.
Attachment "A"
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 battery charger or power supply, suitable for AGM
type batteries, recommended current rating of 70A fixed voltage 13.5V to 14.5V.
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.
