Model year 

From 2015 To 2016

Model Line: 

Cayenne (92A)

Subject: 

Gateway control unit and battery sensor

Information: 

Depending on which component needs to be replaced 'gateway control unit' or 'battery sensor', the existing type must be checked and a new, suitable combination must be used. 

Remedial Action: 

  1. Part number of the existing/removed battery sensor

    (from the vehicle)

    is 958.611.181.11:

    => A new type of battery sensor is already installed in the vehicle.

    => Replace battery sensor, see > 270519 REMOVING AND INSTALLING BATTERY SENSOR 

    => The new type of gateway control unit is also installed and can remain in the vehicle.

    End of action required.

  2. Part number of the existing/removed battery sensor

    (from the vehicle)

    is 958.611.181.10:

    => An older type of battery sensor is installed in the vehicle.

    => Replace battery sensor with new type (Part No.: 958.611.181.11 - NEW - > Battery sensor), see > 270519 REMOVING AND INSTALLING BATTERY SENSOR 

    and

    => Program existing gateway control unit in accordance with the new, required software version, see 'Procedure' section below.

Tools:

> 9900 - PIWIS Tester III with PIWIS Tester software version 33.200 (or higher) installed.

Battery Charger/Power Supply - Suitable for AGM Type batteries, recommended current rating of 70A fixed voltage 13.5V to 14.5V.

Materials: 

95B.907.530.J - NEW - > Gateway control unit

958.611.181.11 - NEW - > Battery sensor

Work Procedure: 

  1. Switch on the ignition using the original driver's key  . On vehicles with "Porsche Entry & Drive", do this by replacing the control unit in the ignition lock with the original driver's key if necessary.
  2. > 9900 - PIWIS Tester III must be connected to the vehicle and switched on.
  3. On the PIWIS Tester start screen, call up the => 'Diagnostics'  menu and select the relevant vehicle type.

    The diagnostic application is then started and the control unit selection screen is populated.

    NOTE: Coding will be aborted in the event of low voltage. 
    • Increased current draw during diagnosis can cause a drop in voltage, which can result in one or more fault entries and the abnormal termination of the coding process.

      → Before commencing work, connect a suitable battery charge or power supply - suitable for AGM Type batteries, recommended current rating of 90A fixed voltage 13.5V to 14.5V to the jump-start terminals in the engine compartment.

    NOTE: Coding will be aborted if the Internet connection is unstable. 
    • An unstable Internet connection can interrupt communication between PIWIS Tester III and the vehicle communication module (VCI). As a result, coding may be aborted.

      → During control unit coding, always connect PIWIS Tester III to the vehicle communication module (VCI) via the USB cable.

  4. Connect a battery charger with a current rating of at least 70 A. 
  5. Re-program gateway control unit.
    5.1 Control units 'Overview' Additional menu call up F7
    5.2 'Campaign'   F12
    5.3 Programming code B1W2X   F12

    Read and follow the information and instructions on the PIWIS Tester  during the guided programming sequence.

    Then press >> to continue.

    During the programming sequence, the control unit is re-programmed and then re-coded automatically if necessary.

    Do not interrupt programming and coding. 

    Once control unit programming - and coding if necessary - is complete, you will be prompted to switch the ignition off and then back on again after a specified waiting time.

    If programming is not completed successfully (error message "Programming unsuccessful"), programming must be repeated. 

  6. Read out and erase all fault memories.
  7. Switch off the ignition.
  8. Disconnect the PIWIS Tester from the vehicle.
  9. For vehicles with Porsche "Entry & Drive", replace the original vehicle key in the ignition lock with the control panel again.
  10. Switch off and disconnect the battery charger.

    End  of action required.
