NOTICE
Fault entry in the fault memory and/or control unit coding aborted due to undervoltage.
•
Increased power consumption during diagnosis can cause a drop in voltage, which can result in one or
more fault entries and cancel the diagnostic process.
Before starting control unit diagnosis, connect a suitable battery charger with a current rating of at least
90 A to the vehicle.
NOTICE
Control unit 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, control unit diagnosis may be aborted.
During control unit diagnosis, always connect the PIWIS Tester to the vehicle communication module (VCI)
via the USB cable.
