WC57 - Re-coding 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. 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:

2013

Vehicle Type:

Boxster (981)/Boxster S (981)

Concerns:

Convertible top status messages in instrument cluster.

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles.
The instrument cluster on the affected vehicles may have been coded with incorrect values
during the production process.
As a result, the messages
•
•
•

“Top is opening”
“Top is closing”
“Top not in final position”

are not displayed in the instrument cluster.
Action
Required:

Re-code the instrument cluster using the PIWIS Tester with test software version 11.250 (or higher)
installed.

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 1,497 vehicles in North America.

Tools:

9818 - PIWIS Tester II with test software version 11.250 (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-1200 and EQ-1105.

Procedure:

See Attachment “A”.

Claim
Submission:

See Attachment “B”.

Attachment "A"
NOTICE
VEHICLE VOLTAGE MUST REMAIN BETWEEN 13.5 AND 14.5 VOLTS DURING THE ENTIRE PROCEDURE.
NOTICE
Coding will be aborted in the event of low voltage.
•

Increased current draw during diagnosis can cause a drop in voltage, which can result in one or more fault
entries and the abnormal termination of the coding process.

⇒

Before commencing work, connect a suitable battery charger with a current rating of at least 40 A to the
jump-start terminals in the engine compartment.
NOTICE

Coding 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, coding 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 coding will be aborted if the vehicle key is not recognized
•

If the vehicle key is not recognized in vehicles with Porsche Entry & Drive, coding cannot be started or will
be interrupted.

⇒

Switch on the ignition using the original vehicle key. To do this, replace the control panel in the ignition
lock with the original vehicle key if necessary.

Information
The procedure described here is based on the PIWIS Tester II software version 11.250.
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.
Work
Procedure:

NOTE: VEHICLE VOLTAGE MUST REMAIN BETWEEN 13.5 AND 14.5 VOLTS DURING THE ENTIRE
PROCEDURE.
1

Connect a battery charger with a current rating of at
least 40 A.
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.

3

9818 - PIWIS Tester II with software version
11.250 (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.

4

On the PIWIS Tester start screen, call up the ⇒
’Diagnostics’ menu and select the vehicle type ⇒
’Boxster/Cayman’ ⇒ ’981’.
The diagnostic application is then started and the
control unit selection screen is populated.
