WE27 - Re-programming Convertible Top Control Unit (Stop Sale 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.

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
Programming interrupted
•
Malfunctions in control unit
•
Risk of damage to control unit

Route the line between the PIWIS Tester and the vehicle communication module (VCI) without tension to
prevent the line from slipping out of the USB connection on the PIWIS Tester.

Lock connecting lines on the vehicle communication module (VCI) using the bayonet lock.

Route the line between the vehicle communication module (VCI) and diagnostic socket on the vehicle
without tension and make sure that the connector is inserted fully into the diagnostic socket.

Check that the rechargeable battery for the PIWIS Tester is charged sufficiently. Connect the PIWIS Tester
to the mains power supply if necessary.
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.

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"'.
2
Code the convertible top control unit before starting control unit programming.
2.1
Select  'Convertible top' control unit in the control unit selection screen ( 'Overview'
menu) and press •>>“ to confirm your selection.
2.2
Once the convertible top control unit has been found and is displayed in the overview, select
the  'Codings/adaptations' menu.
2.3
Select the  'Automatic coding' function and press •>>“ to start coding.
2.4
When coding is complete, the message "Coding has been completed successfully" is
displayed and a tick appears in the 'Status' box.

Required PIWIS Tester software version:
13.800 (or higher)*
* If the campaign is carried out using the PIWIS
Tester software version 13.800, the convertible
top control unit must be re-coded before starting
programming.
 For details of the procedure, see "Preliminary
work".
Type of control unit programming:
Control unit programming using the 'Campaign'
function in the Additional menu on the PIWIS
Tester by entering a programming code.
Programming code:
G7M2V
Programming sequence:
Read and follow the information and instructions
on the PIWIS Tester during the guided
programming sequence.
The convertible top control unit is re-programmed
and then re-codedautomatically during the
programming sequence.
Do not interrupt programming and coding.
Information on the programming
sequence:
If coding is not carried out successfully during
the guided programming sequence, this can be
ignored provided coding was already carried
out successfully before starting control unit
programming.
In this case, the control unit does not have to be
re-coded again separately when the programming
sequence is complete.
Once the PIWIS Tester software version 13.900
(or higher) becomes available, it will no longer be
necessary to code the control unit before starting
control unit programming.
