Model Year:

As of 2014 up to 2016

Subject:

High-voltage battery

Information:

Modified procedure for high-voltage battery replacement
•

Due to a delay in the rollout of the battery repair concept to other markets because of training
restrictions due to the Covid-19 situation, after the replacement high-voltage batteries for the
Panamera S E-Hybrid (970) have been used up either the high-voltage battery of the Cayenne S
E-Hybrid (92A) must either be used again in the RoW regions, or battery repair must be carried out at
the Porsche dealer, depending on the qualification status.

•

The cell modules and, if necessary, other parts continue to be replaced in the USA (PCNA)
(component replacement).

•

Once the relevant repair measure has been carried out, it may be necessary to re-program the
high-voltage battery and air-conditioning control units.

•

The previous Technical Information, Group 2, No. 88/19, which describes the procedure for general
use of the Cayenne S E-Hybrid (92A) high-voltage battery in the Panamera S E-Hybrid (970), is no
longer valid in this form and has been removed from the Porsche Central Service System (PCSS).

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

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, depending on the
market:
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.

Information
The Canadian market is not linked to the procedure in the USA. In the event a replacement is required for
the high-voltage battery, the procedure "RoW" must be used.
RoW incl. Canada:
•

Your Porsche dealer is currently not authorized to perform repairs on the high-voltage battery
independently: Order the Cayenne S E-Hybrid (92A) high-voltage battery, convert it for use in the
Panamera S E-Hybrid (970) and then install it, see  Technical Information 'Procedure - Remaining
markets (RoW)'.

•

Your Porsche dealer is authorized to perform repairs on the high-voltage battery independently:
The vehicle is repaired at the Porsche dealer; see  Technical Information 'Procedure - Remaining
markets (RoW/China) - Repairs in the Porsche Centre'.

Procedure - USA (PCNA)
WARNING
Incorrect handling of high-voltage components
•

Electric shock

•

Short circuit

•

Fire

•

Explosion



Only appropriately trained and authorized persons are permitted to work on high-voltage vehicles and
components.



Required qualification: High-voltage technician or high-voltage expert.



Observe all safety regulations.



Always use insulated tools, e.g. VAS 6883 High-voltage tool set, when working on these components.



Observe general warning notes for working on the high-voltage vehicle electrical system.  Workshop
Manual '2X00IN General warning notes for working on the high-voltage vehicle electrical system'
WARNING

Danger of fire, explosion
•

Insulation fault as a result of coolant leaking into high-voltage battery



Always drain the high-voltage battery cooling lines completely before transporting/handling the
high-voltage battery.

Information
The Canadian market is not linked to the procedure in the USA. In the event a replacement is required
for the high-voltage battery, the procedure "RoW" must be used. See  Technical Information '2X00IN
Procedure - Remaining markets (RoW/China)'.

Information
If the high-voltage battery needs to be replaced, approval must first be obtained from Technical
Support of the PCNA. Once approval has been obtained, please see PPN for the ordering procedure:

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
During programming, the taught-in battery capacities are also reset.

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.
