WD47 - Re-programming Porsche Stability Management (PSM) Control Unit (Workshop
Campaign)
Note:

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:

2014

Vehicle Type:

Panamera/Panamera 4/Panamera S E-Hybrid
Panamera S/Panamera 4S/Panamera GTS/Panamera Turbo

Concerns:

Porsche Stability Management (PSM) control unit

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. After one
hundred actuations, the electric parking brake performs a calibration run at a vehicle speed of
9 mph (15 km/h).
Due to a software error in the PSM control unit, the engine torque is reduced briefly to protect
the electric parking brake. The customer may notice this as a loss of power.
To prevent this loss of comfort, the control unit must be re-programmed with an updated data record.

Action
Required:

Re-program PSM control unit using an updated data record.
Information
The total time required for programming and coding is approx. 5 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 3,017 vehicles in North America.

Tools:

•
•

9818 - PIWIS Tester II with PIWIS Tester software version 12.900 (or higher) installed.
Battery Charger/Power Supply - Suitable for AGM Type batteries, recommended current rating of
70A fixed voltage 13.5V to 14.5V. Refer to Equipment Information EQ-1105.

Work
Procedure:

See Attachment “A”.

Claim
Submission:

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 commencing work, connect a suitable battery charger or power supply, suitable for AGM type
batteries, recommended current rating of 70A fixed voltage 13.5V to 14.5V to the jump-start terminals in
the engine compartment.

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.

1

Connect a battery charger or power supply, suitable for AGM type batteries, recommended
current rating of 70A fixed voltage 13.5V to 14.5V to the jump-start terminals in the engine
compartment and switch it on.

2

Only for Panamera S E-Hybrid:

4

Disconnect electric plug connection for the fan
blower  Disconnecting connector -1- ( Disconnecting connector -arrow-) to prevent the blower
from coming on during control unit programming.
Having the fan on and the associated increased
current draw can cause a drop in voltage, which
can result in abnormal termination of control unit
programming.

Disconnecting connector
3

Switch on the ignition using the original driver's key. On vehicles with “Porsche Entry & Drive”,
do this by replacing the control panel in the ignition lock with the original driver's key if necessary.

4

9818 - PIWIS Tester II with software version 12.900 (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.

Re-programming PSM control unit
Information
The procedure described here is based on the PIWIS Tester II software version 12.900.
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.

Information
The rear spoiler may extend automatically during programming.
Do not work in this area during programming.
