Information:

Procedure for high-voltage battery replacement
•

Depending on the market, the high-voltage battery will now either be replaced by the original
Cayenne S E-Hybrid high-voltage battery (complete battery replacement) as previously, or the cell
modules and, if necessary, other parts will be replaced (component exchange).

•

Once the relevant repair measure has been performed, it may be necessary to re-program the
high-voltage battery control unit.

Information
HV battery replacement is under the Approval and Support Management process and procedures should
be followed.
Action required: Depending on the relevant market and whether the respective Porsche dealer is authorized to perform
repairs on the high-voltage battery independently, various repair concepts for the high-voltage battery are
provided. You will find the repair concept for your market and the relevant procedure for rectifying faults
on the high-voltage battery in the  Technical Information 'Replacing the 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 Infor-mation
'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 incl. Canada" must be used.
All other markets (RoW incl. Canada):
Please note the different procedures depending on whether or not the respective Porsche dealer is
already entitled to carry out repairs on the high-voltage battery independently.
•

Your Porsche dealer is currently not authorized to perform repairs on the high-voltage battery
independently: Order and then install the Cayenne S E-Hybrid (92A) spare part high-voltage battery,
see  Technical Information 'Procedure - Remaining markets (RoW/China)'.

•

Your Porsche dealeris 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 PC'.

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 this may be different in a higher
version.
Procedure in the event of error messages
appearing during the programming
sequence:

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.

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.
