Technical Information

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 WLAN 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 recognised
•

If the driver's key is not recognised in the vehicle, coding cannot be started or will be interrupted.



Place the driver's key with the back facing down into the front left storage compartment in the centre
console to guarantee a continuous radio link between the vehicle and the driver's key.

Work Procedure: 1

2

Place the driver's key with the back facing down
into the front left storage compartment in the center
console  Driver's key in storage compartment.
This will guarantee an uninterrupted radio link
between the vehicle and the driver's key.

3

9900 - PIWIS Tester 3 must be connected to the
vehicle communication module (VCI) via the USB
cable. Then connect the communication module
to the vehicle and switch on the PIWIS Tester.

Connect a battery charger/power supply suitable for
AGM Type batteries, recommended current rating of
90A fixed voltage 13.5V to 14.5V.
First connect the positive cable of the charger to the
positive terminal  Jump-start terminals -2- and
then connect the negative cable of the charger to
the ground point for jump-lead starting  Jump-start
terminals -3-.
Then switch on the battery charger and start trickle
charging the battery.

Switch on the ignition.

NOTICE
Use of a PIWIS Tester software version that is older than the prescribed version
•

Measure is ineffective



Always use the prescribed version or a higher version of the PIWIS Tester software for control unit coding.

Information
The procedure described here is based on the PIWIS Tester software version 36.600.010.
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:

Control unit selection - Gateway
1

Select the 'Gateway' control unit in the control unit selection screen ('Overview' menu) and confirm
your selection by pressing •F12“ ('Next') .

2

When the question “Create Vehicle Analysis Log (VAL)?” appears, either press •F12“ ('Yes') to
create a VAL or press •F11“ ('No') if you do not want to create a VAL.

3

Press •F12“ ('Next') to acknowledge the message informing you that campaigns for the vehicle are
