Replacement of High-Voltage Battery - Observe Modified Procedure (139/20)

Vehicle Type:

Panamera S E-Hybrid (970)

Model Year:

As of 2014 up to 2016

Subject:

High-voltage battery

Information:

Modified procedure for high-voltage battery replacement
•

From now on, if the high-voltage battery of the Panamera S E-Hybrid (970) needs to be replaced, the
high-voltage battery of the Cayenne S E-Hybrid (92A) will no longer be used.

•

Panamera batteries will be provided by our local remanufacturing partner: Spiers New Technologies.

•

The previous Technical Information, Group 2, No. 88/19, which describes the procedure for using
the high-voltage battery of the Cayenne S E-Hybrid (92A) in the Panamera S E-Hybrid (970), is
therefore no longer valid and has been removed from the Porsche Central Service System (PCSS).
The Electronic Parts Catalogue (PET) has also been updated accordingly.

Information
HV battery replacement is under the Approval and Support Management process and procedures should
be followed.
Remedial
Action:

Various repair concepts are available for the high-voltage battery, depending on the respective market.
You will find the repair concept for your specific market and the relevant procedure for rectifying faults on
the high-voltage battery in the  Technical Information 'Replacement of high-voltage battery' section.

Replacing the high-voltage battery
Work
Procedure:

The following repair concepts are currently available for the high-voltage battery:
•

USA (PCNA): Coordinate approval for a replacement high-voltage battery with Technical Support
of the PCNA, who will then assume responsibility for procuring the battery from Spiers Inc., see 
Technical Information 'Procedure - USA (PCNA)'. Then return the old battery to Spiers Inc.

Work Procedure: 1

Create vehicle analysis log (VAL) using the PIWIS Tester.
Mark the vehicle analysis log you have just created with the attribute "Initial VAL" and after
programming the control units, return it using the PIWIS Tester.

2

Remove the old battery, see  Workshop Manual '270855 Replacing high-voltage battery' and then
prepare for subsequent transportation to Spiers Inc. according to the respective battery status, see
 Workshop Manual '2X00IN Packing high-voltage battery with battery status "Normal" (not critical)'
or  Workshop Manual '2X00IN Packing high-voltage battery with battery status "Warning" (critical)'.

3

Install new high-voltage battery supplied by Spiers Inc., see  Workshop Manual '270855 Replacing
high-voltage battery'.

For specific information on control unit programming during this remedial action, see
the table below.
Required PIWIS Tester software version:

39.600.030 (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:

C3B4V

Programming sequence:

Read and follow the information and instructions
on the PIWIS Tester during the guided
programming sequence.
The high-voltage battery and air-conditioning
control units are re-programmed and then
re-codedautomatically during the programming
sequence.
Do not interrupt programming and coding.

Software version programmed during this
campaign:
The software version of the programmed
data record is based on the specified
PIWIS Tester test software version. Please
note that these may have changed in a
higher version.
Procedure in the event of error messages
appearing during the programming
sequence:

High-voltage battery control unit: 1300
Air-conditioning control unit: 1040
Following control unit programming, the software
version can be read out of the relevant control unit in
the 'Extended identifications' menu using the PIWIS
Tester.

 Workshop Manual '9X00IN Basic instructions and
procedure for control unit programming using the
PIWIS Tester - section on "Fault finding"'.

Information
Once the high-voltage battery control unit has been re-programmed, a diagnosis of the high-voltage
battery is performed the next time the BUS is idle (ignition is switched off and the vehicle is locked). This
process must not be interrupted. If the diagnosis is aborted because the vehicle was locked while the
diagnosis was running, for example, a fault memory is stored.
