WJ60 - Adapting Vehicle Order in the Instrument Cluster and Re-Coding PCM and
Air-Conditioning Control Unit (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:

2019

Model Line:

Cayenne (9YA)

Subject:

Instrument cluster

Information:

Due to a faulty Timer function for the internal clock in the instrument cluster, there is a possibility that the control unit system will be activated cyclically by the instrument cluster after
stopping the vehicle.
As a result, the control unit system will not be switched to energy-saving mode, resulting in increased
closed-circuit current consumption. This can deplete the vehicle battery if the vehicle is idle for a long
time.

Remedial
Action:

Adapt the vehicle order and re-code the PCM and air-conditioning control unit using the PIWIS Tester with
software version 37.600.025 (or higher) installed.

NOTICE
Use of a PIWIS Tester test 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 test software for control unit
coding.

Important:

Please complete campaign repair during PDI for any affected vehicle.

Affected
Vehicles:

Only the vehicles assigned to the campaign (see also PIWIS Vehicle information). This campaign affects
484 vehicles in North America.

Required tools
Tools:

•

9900 - PIWIS Tester 3 with PIWIS Tester software version 37.600.025 (or higher) installed

Battery charger with a current rating of at least 90 A and a current and voltage-controlled
charge map for lithium starter batteries, e.g. VAS 5908 - Battery charger 90A

Information
The new Cayenne is equipped as standard with a lithium starter battery, which must only be charged
using suitable battery chargers.
For further information about the battery chargers to be used, see:
•

 Workshop Manual '2706IN General information on the 12-volt lithium-ion battery'

•

 Workshop Manual '270689 Charging vehicle electrical system battery'

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 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 recognized
•

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



Position the driver's key in the rear area of the left cupholder in the center console between the holding
struts (emergency start tray) in order to guarantee a permanent radio link between the vehicle and
driver's key.

Work Procedure: 1

Page 2 of 8

Connect a battery charger that is suitable for lithium starter batteries with a current rating of
at least 90 A (e.g. VAS 5908 - Battery charger 90A) to the jump-start terminals in the engine
compartment.
For instructions, see  Workshop Manual '2706IN External power connection, jump-lead starting'.
