WMM8 - Enabling Functions on Media Interface (Workshop Campaign)
Important:
CRITICAL WARNING -This campaign includes steps where control unit(s) in the vehicle will be
programmed with the PIWIS Tester. The vehicle voltage must be maintained between 13.5 volts and 14.5
volts during this programming. Failure to maintain this voltage could result in damaged control unit(s).
Damage caused by inadequate voltage during programming is not a warrantable defect. The technician
must verify the actual vehicle voltage in the PIWIS Tester before starting the campaign and also document
the actual voltage on the repair order.
Model Year:
2022
Vehicle Type:
Macan (95B)/Macan S (95B)/Macan GTS (95B)
Concerns:
Porsche Communication Management
Information:
Due to a lack of function enabling in the backend, there is a possibility that the media playback
of the USB stick and iPod® as well as Apple CarPlay® via the USB interface in the center
console will not work on the affected vehicles.
The required enabling in the backend has been performed in the interim period.
Action required Perform function enabling using the PIWIS Tester.
Information
The total time required for enabling functions is approx. 5 minutes.
Affected
Vehicles:
Only vehicles assigned to the campaign (see also PCSS Vehicle Information).
Required tools
Tools:
•
•
9900 - PIWIS Tester 3 with PIWIS Tester software version 40.550.050 (or higher) installed
Battery charger with a current rating of at least 90 A and - if required - also with a current- and
voltage-controlled charge map for lithium starter batteries, e.g. VAS 5908 battery charger
90 A
For further information about the battery chargers to be used, see  Workshop Manual '2X00IN Battery
trickle charging'.

Preparatory work
NOTICE
Fault entry in the fault memory and/or control unit coding aborted due to low voltage.
•
Increased current draw during diagnosis or control unit coding can cause a drop in voltage, which can
result in one or more fault entries and the abnormal termination of the coding process.

Before starting control unit coding, connect a suitable battery charger with a current rating of at least 90 A
to the vehicle.
NOTICE
Coding will be aborted if the WiFi connection is unstable.
•
An unstable WiFi connection can interrupt communication between the PIWIS Tester and the vehicle
communication module (VCI). As a result, coding may be aborted.

During control unit coding, always connect the PIWIS Tester to the vehicle communication module (VCI) via
the USB cable.
NOTICE
Control unit coding will be aborted if the driver's key is not recognized
•
If the driver's 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 unit in the ignition lock
with the original driver's key if necessary.
Information
The procedure described here is based on the PIWIS Tester 3 software version 40.550.050.
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.
Work Procedure: 1

Connect a battery charger with a current rating of at least 90 A (e.g. Battery charger 90 A) to the
jump-start terminals in the engine compartment and switch it on.
2
Switch on the ignition using the original driver's key. On vehicles with "Porsche Entry & Drive", do
this by replacing the control unit in the ignition lock with the original driver's key if necessary.
3
Connect 9900 - PIWIS Tester 3 to the vehicle communication module (VCI) via the USB cable.
Then connect the communication module to the vehicle and switch on the PIWIS Tester.

Concluding work
Work Procedure:
Information
If control units are found to have faults that are not caused by control unit coding, these must first be
found and corrected. This work cannot be invoiced under the workshop campaign number.
1
Read out the fault memory and check any existing fault memory entries.
2
Delete the fault memory.
3
Switch off ignition.
4
Disconnect 9900 - PIWIS Tester 3 from the vehicle.
5
On vehicles with Porsche Entry & Drive, replace the original driver's key in the ignition lock with the
control unit again.
6
Disconnect the battery charger.
7
Enter the campaign in the Warranty and Maintenance booklet.
