WE17 - Re-programming High-voltage Battery Control Unit (Workshop 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.
ADDITIONAL WARNING FOR PLUG-IN HYBRID VEHICLES - A HIGH VOLTAGE CHARGER CONNECTED
TO THE VEHICLE IS NOT SUFFICIENT FOR PROGRAMMING PURPOSES. DURING A PROGRAMMING
PROCEDURE, THE HIGH VOLTAGE CONTACTS MAY BE DISCONNECTED RESULTING IN A LOW VOLTAGE
CONDITION IN THE 12 VOLT SYSTEM DURING PROGRAMMING. THE LOW VOLTAGE BATTERY MUST STILL
BE CHARGED WITH AN APPROVED CHARGER.

Model Year:

2014

Vehicle Type:

Panamera S E-Hybrid

Country/Market:

USA (C02)
Canada (C36)

Concerns:

High-voltage battery control unit

Information:

This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. The
error message "Hybrid system failure - Park vehicle safely" can appear sporadically in the
instrument cluster on the affected vehicles because the high-voltage system diagnostic
function is too sensitive.

Action
Required:

Re-program the high-voltage battery control unit.
Information
The total time required for programming and coding the control unit is approx. 12 minutes.
•

It takes about 6 minutes to program the high-voltage battery control unit.

•

Once programming is complete, a control unit run-on phase of at least 6 minutes with the ignition
switched off is required so that on-board diagnosis of the high-voltage system can be performed.
The vehicle cannot be started until on-board diagnosis is completed successfully.

Affected
Vehicles:

The VIN(s) can be checked by using PIWIS Vehicle Information link to verify if the campaign affects the
vehicle. This campaign is scope specific to the VIN! Failure to verify in PIWIS may result in an improper
repair. This campaign affects 615 vehicles in North America.

9818 - PIWIS Tester II with PIWIS Tester software version 13.800 (or higher) installed
Battery Charger/Power Supply - Suitable for AGM Type batteries, recommended current rating of
70A fixed voltage 13.5V to 14.5V. Refer to Equipment Information EQ-1105.

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.



Switch on the ignition using the original vehicle key. To do this, replace the original vehicle key in the
ignition lock with the plastic key fob if it was previously removed at the start of this procedure.

Work
Procedure:

NOTE: VEHICLE VOLTAGE MUST REMAIN BETWEEN 13.5 AND 14.5 VOLTS DURING THE ENTIRE WORK
PROCEDURE.

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

Programming sequence:

Do not interrupt programming and coding.
Programming time (approx.):

12 minutes
Once the control unit has been programmed and
coded, you will be prompted 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.

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 the control units are found to have further faults, which cannot be erased and are not caused by
control unit programming, these faults must be located and corrected.
This work cannot be invoiced under the workshop campaign number.
