WE02 - Re-programming Instrument Cluster (Workshop Campaign)

Important 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:

As of 2012 up to 2014

Model Line:

Boxster (981)
Cayman (981)
911 (991)

Concerns:

Instrument cluster

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. The following
fault symptoms can occur on the affected vehicles due to a software error in the instrument
cluster:

Action
Required:

•

Failure of the display on the multi-function display: The display on the multi-function display in the
instrument cluster can stop working at times under certain conditions. The display starts working
again after a certain time.

•

Implausible service reminder indicator display: The driver is informed that a service (maintenance,
intermediate maintenance or oil service) is due although the mileage and date for a required service
have not yet been reached.

Re-program the instrument cluster.
Information
It takes about 20 minutes to program and code the instrument cluster.

Information
When the instrument cluster is re-coded, the individual settings implemented in the instrument cluster
by the customer will be lost and are reset to the default values of the country version that applies to
the vehicle.
After carrying out the campaign, therefore, please inform your customers that personal settings
they have implemented in the instrument cluster will have to be set again and provide them with any help
and support they need for setting the relevant options.
This affects the following settings in the Vehicle menu, for example:
•

Lowering of exterior mirror on passenger’s side during parking manouvers

•

Locking settings

•

Light & Visibility settings

•

Units (kilometers/miles, Celsius/Fahrenheit, ...)

•

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 36,963 vehicles in North America.

Tools:

Work
Procedure:

See Attachment “A”.

Claim
Submission:

See Attachment “B”.

9818 - PIWIS Tester II with test software version 13.500 (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.

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.

Work Procedure: 1

Carry out general preliminary work for control unit programming as described in  Workshop
Manual '9X00IN Basic instructions and procedure for control unit programming using the PIWIS
Tester - section on "Preliminary work"'.

Carrying out control unit programming
Work
Procedure:

Note: Vehicle voltage must remain between 13.5 and 14.5 volts during entire work procedure.

Read and follow the information and instructions
on the PIWIS Tester during the guided
programming sequence.
During the programming sequence, the instrument
cluster is re-programmed and then re-codedautomatically.

Programming sequence:

The display in the instrument cluster is switched off
during programming. "bLF" appears on the digital
speedometer 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.
Time required for programming and
coding (approx.):

20 minutes

Once you have read out the fault memories, delete
the fault memory entries by pressing •F8“.

Press •F12“ (“Yes”) in response to the question as
to whether you really want to erase all fault memory
entries.

Erasing fault memories

The faults stored in the fault memories of the various control units are deleted.
Information
If the fault memories of individual control units (e.g. DME, PDK, etc.) cannot be erased, start the engine
briefly and then switch it off again. Wait for approx. 10 seconds before switching the ignition on again and
re-establish the connection between the PIWIS Tester and the vehicle. Then read out and erase the fault
memories of the affected control units again separately.
If the fault memory entries are still present, proceed as follows:
•

Switch off ignition.

•

Disconnect the PIWIS Tester diagnostic connector from the diagnostic socket.

•

Lock the vehicle using the driver's key.

•

Wait for approx. 1 minute before unlocking the vehicle again and then read out the fault memories of
the control units again and erase them.

If control units are found to have faults, which cannot be erased and are not caused by control unit
programming, these faults must be found and corrected. This work cannot be invoiced under the
workshop campaign number.
