Required tools
Tools:
•
•
9900 - PIWIS Tester 3 with installed PIWIS Tester test software version 39.400.030 (or higher)
Battery charger with a current rating of at least 90 A, e.g. VAS 5908 Battery charger 90A.
Preparatory work
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 getting started, connect a suitable battery charger with a current rating of at least 90 A to the
jump-start terminals.
NOTICE
Control unit programming will be aborted if the WLAN connection is unstable.
•
An unstable WiFi connection can interrupt communication between the PIWIS Tester and the vehicle
communication module (VCI). As a result, programming may be aborted.

During control unit programming, always connect the PIWIS Tester to the vehicle communication module
(VCI) via the USB cable.
NOTICE
Control unit programming 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.
