required.

1.9

If the 'high-voltage battery' control unit does not have the software version 1101 →
Re-program the 'high-voltage battery' control unit as described below.

Re-program 'high-voltage battery' control unit

Preliminary Work
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 suitable 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 WLAN connection is unstable.
•

An unstable WLAN 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 power supply unit 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.



Switch on the ignition using the original driver’s key. To do this, replace the control panel in the ignition
lock with the original driver’s key if necessary.
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"'.

Information
The procedure described here is based on the PIWIS Tester II software version 15.300.
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
Once control unit programming is complete, the windscreen wipers can start wiping.
Do not work in this area or place any objects on the windshield during programming.
Re-program 'high-voltage battery' control unit with software version 1101
The basic procedure for programming a control unit is described in the Workshop Manual  Workshop
Manual '9X00IN Basic instructions and procedure for control unit programming using the PIWIS Tester section on "Programming"'.
Required PIWIS Tester software version:

15.410 (or higher)

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:

Technical Information

57/15

Read and follow the information and instructions
on the PIWIS Tester during the guided programming
sequence.
The 'high-voltage battery' control unit is first
re-programmed and then re-codedautomatically
during the programming sequence.

Programming sequence:

Do not interrupt programming and coding.
12 minutes

Programming time (approx.):

Once programming and coding is complete, the PIWIS
Tester will prompt you to switch the ignition off and
then back on again after a waiting time of 6 minutes.
The 6-minute waiting time with the ignition switched
off is necessary so that on-board diagnosis of
the high-voltage system can be performed and
completed as required after control unit programming.
The vehicle cannot be started until on-board diagnosis
is completed successfully.
Fault memory entries that were entered as a result of
control unit programming can only be deleted after
on-board diagnosis has been completed successfully.

Programmed software version:

Following control unit programming, the software
version can be read out of the 'high-voltage battery'
control unit in the  'Extended identifications' menu
using the PIWIS Tester.

Procedure in the event of error messages
appearing during the programming
sequence:

procedure for control unit programming using the
PIWIS Tester - section on "Troubleshooting"'.

Procedure in the event of abnormal termination of control unit programming:

Repeat control unit programming by entering the
programming code again.

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

Information
If the engine will not start and the prompt "Park vehicle safely" appears in the instrument cluster, on-board
diagnosis of the hybrid system may not have been completed fully.
If this happens, switch off the ignition, disconnect the PIWIS Tester from the diagnostic socket on the
vehicle and lock the vehicle. Wait for at least 6 minutes. Then unlock the vehicle and try to start the
engine again.

Information
If the passive (greyed) fault memory entry "D00000 - Function restriction due to fault in PSM" is
entered in the 'Electric power steering' control unit, please ignore this. The fault memory entry is stored
as a result of a communication problem between the control units caused by the PIWIS Tester connected
to the vehicle.
If control units are found to have other faults, which cannot be erased and are not caused by control unit
programming, these faults must be found and corrected.
