Service Technical Information 195/21 ENU 9025 9 Rear Seat Belt Warning Implausible/ No Phonebook Scroll Function Available: Check and Update Instrument Cluster as Necessary (195/21) Change overview Version Date Note 1.0 12/23/2021 First publication 1.1 01/05/2022 Update of title 2.0 02/18/2022 Macan vehicles added from model year 2022 (N) Model Line: Macan (95B) Model Year: As of 2019 up to 2022 Concerns: Instrument cluster Information: New software is available for the instrument cluster. This software will correct the following topics: • Implausible rear seat belt warning After a passenger has got out of the rear seat, a seat belt warning message appears for the corresponding rear seat after the trip has continued, although this seat is no longer occupied in the meantime. • Phonebook scroll function not available The list of phonebook entries is not available in the multi-function display on the instrument cluster. As a result, contacts cannot be displayed and selected. Action required: In the event of a customer complaint, check the software version of the instrument cluster and re-program the instrument cluster with the appropriate programming code. Overview of the software versions affected • Vehicles model years 2019 - 2021: Software version (old version) Software version (new version) 1830 0833 0835 0838 0845 0839 0841 0843 AfterSales Feb 18, 2022 Page 1 of 5 9 Service Technical Information ENU 195/21 9025 • Model year 2022 vehicles: Software version (old version) Software version (new version) 0209 0211 Information • The total time required for control unit programming is approx. 100 minutes. Required tools Tool: • • 9900 - PIWIS Tester 3 with PIWIS Tester software version 40.785.070 (or higher) installed Battery charger with a current rating of at least 90 A, e.g. VAS 5908 battery charger 90A. Preparatory work NOTICE Fault entry in the fault memory and control unit programming aborted due to low voltage. • Increased current draw during diagnosis or control unit programming can cause a drop in voltage, which can result in one or more fault entries and the abnormal termination of the programming process. Before getting started, connect a suitable battery charger with a current rating of at least 90 A to the jump-start terminals. NOTICE Control unit programming 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, programming may be aborted. During control unit programming, always connect the PIWIS Tester to the vehicle communication module (VCI) via the USB cable. Feb 18, 2022 Page 2 of 5 AfterSales Service Technical Information 195/21 ENU 9025 9 NOTICE Control unit programming will be aborted if the driver's key is not recognized • If the driver's key is not recognized in vehicles with Porsche Entry & Drive, programming cannot be started or will be interrupted. Switch on the ignition using the original driver’s key. To do this, replace the control unit in the ignition lock with the original driver’s key if necessary. Work Procedure: 1 2 Carry out general preliminary work for control unit programming as described in Workshop Manual '9X00IN Basic instructions and procedure for control unit programming - section on "Preliminary work"'. Read out the software version. 2.1 Connect the PIWIS Tester to the vehicle and switch on the PIWIS Tester. 2.2 Switch on ignition. 2.3 Start diagnostics. 2.4 Select "Instrument cluster" control unit. 2.5 Select the "Extended identifications" tab. 2.6 Read out and note the software version. Re-programming instrument cluster Information Depending on the previous software version, the new software version may result in changes to the visual and audible seat belt warning with regard to the switch-on threshold, display logic and duration as well as the possibility of acknowledging the warning. Therefore, please inform your customers after the implementation of the measure that the seat belt warning may behave differently than before.
