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) Revision: This bulletin replaces bulletin Group 9 195/21, dated December 23, 2021. Model Year: As of 2019 up to 2021 Model Line: Macan (95B) 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 Software version (old version) Software version (new version) 1830 0833 0835 0838 0845 0839 0841 0843 Information • The total time required for control unit programming is approx. 100 minutes. AfterSales Jan 5, 2022 Page 1 of 4 9 Service Technical Information ENU 195/21 9025 Required tools Tool: • • 9900 - PIWIS Tester 3 with PIWIS Tester software version 40.700.020 (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. 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 Jan 5, 2022 Page 2 of 4 Perform preliminary work for programming the relevant control units according to 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. AfterSales Service Technical Information 195/21 ENU 9025 9 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. Work Procedure: 1 The basic procedure for control unit programming is described in the Workshop Manual Workshop Manual '9X00IN Basic instructions and procedure for control unit programming - section on "Programming".' . Specific information on control unit programming in the context of this Technical Information: Required PIWIS Tester software version: 40.700.020 (or higher) Type of control unit programming: Control unit programming using the 'Campaign' function in the Additional menu on the PIWIS Tester by entering a programming code. Software version: 1830 Programming code: P2K2K Software version: 0833 Programming code: P8H8J Software version: 0835, 0838, 0839 Programming code: D2X7E Software version: 0841 Programming code: T7G4Z Software version: 0843 Programming code: X8P3G Programming sequence: Read and follow the information and instructions on the PIWIS Tester during the guided programming sequence. During the programming sequence, the instrument cluster control unit is re-programmed and then automatically re-coded. Do not interrupt programming. AfterSales Jan 5, 2022 Page 3 of 4 9 Service Technical Information ENU 195/21 9025 Programming time (approx.): 100 minutes Software version programmed during this campaign: 0845 Procedure in the event of error messages appearing during the programming sequence: Workshop Manual '9X00IN Basic instructions and procedure for control unit programming - section on "Fault finding"'. Procedure in the event of abnormal termination of control unit programming: Repeat control unit programming by restarting programming. Following control unit programming, the software version can be read out of the instrument cluster control unit in the 'Extended identifications' menu using the PIWIS Tester. Concluding work Work Procedure: 1 General subsequent work for control unit programming as described in Workshop Manual '9X00IN Basic instructions and procedure for control unit programming using the PIWIS Tester section on "Subsequent work"' .
