Preparatory work (971)
NOTICE
Fault entry in the fault memory and/or control unit coding aborted due to undervoltage.
•
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 the vehicle, coding cannot be started or will be interrupted.

Place the driver's key with the back facing down in the area in front of the storage compartment under
the armrest (emergency start tray) in order to guarantee a permanent radio link between the vehicle and
driver's key.
