Service Technical Information 236/22 ENU WNT1 9 WNT1 - Re-Programming Connect Control Unit and Central Computer (PCM) (Cluster 37) (Workshop Campaign) Revision: This bulletin replaces bulletin Group 9 236/22 WNT1, dated July 28, 2023. Model Year: 2022 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 Line: Panamera (971) Concerns: Connect control unit and central computer (PCM) Cause: Optimized software is available for the Connect control unit and central computer (PCM) control unit. Measures: • • • Depending on the booked scope, the Connect control unit and the central computer (PCM) control unit must be re-programmed with the latest PIWIS Tester software version. Minimum requirement: Version 42.000.030 Replace Owner's Manual in the on-board folder in the vehicle with an updated version. Checklist: For better clarity, a checklist was created as an aid for carrying out the campaign. This does not replace TI. The checklist does not have to be attached to the job line in PCSS. For checklist, see Technical Information 'Checklist' Affected Vehicles: Only vehicles assigned to the campaign (see also PCSS Vehicle Information). Required tools Tools: • • • • 9900 - PIWIS Tester 3/ 4 Battery charger with a current rating of at least 90 A, e.g. VAS 5908 battery charger 90A USB storage medium Type A+C 32 GB (for PCM update), Part No. V04014999WW000 USB storage medium, type C (for onboard Owner's Manual update), e.g. Part No. V04014999WW000 AfterSales Sep 27, 2023 Page 1 of 12 9 Service Technical Information ENU 236/22 WNT1 Re-programming Connect control unit and central computer (PCM) (Cluster 37) Information If a deviation in the integration test is still indicated despite programming being carried out, this must be repeated. If the deviation persists, contact Technical Support. Work Procedure: Information Before starting programming, particular attention must be paid to the following: • The charger must be switched off and on once; the battery charger display must be off before starting it again, because the battery charger automatically switches to trickle charging after 5 hours (default setting in the charger). • Set charge voltage to 14.6 volts. • Operate in charging mode. • Vehicles with a PVTS contract must be activated for Service mode. • The PIWIS Tester must not be charged using the cigarette lighter! 1 Create Vehicle Analysis Log (VAL) using the PIWIS Tester. Mark the vehicle analysis log you have just created with the attribute “Pre-VAL” and after carrying out the campaign, return it using the PIWIS Tester. If Scope 1 is assigned to the vehicle, continue with Step 2. If Scope 6 is assigned to the vehicle, continue with Step 3. 2 Program Connect control unit. If Scope 6 is assigned to the vehicle, continue with Step 4. For specific information on control unit programming during this campaign, see table below. Sep 27, 2023 Page 2 of 12 Required PIWIS Tester software version: 42.000.030 (or higher) Type of control unit programming: Control unit programming using the ‘Automatic programming’ function of the Connect control unit. AfterSales Service Technical Information 236/22 ENU WNT1 Programming sequence: 9 The basic procedure for control unit programming is described in the Workshop Manual Workshop Manual 'Basic Instructions and Procedure for Control Unit Programming Using the PIWIS Tester'. Read and follow the information and instructions on the PIWIS Tester during the guided programming sequence. Do not interrupt programming and coding. A backup documentation process for the re-programmed software versions starts as soon as programming and coding is complete. Programming time (up to): 25 minutes Control units programmed in this campaign: • Procedure in the event of error messages appearing during the programming sequence: Workshop Manual '9X00IN Basic instructions Procedure in the event of a termination in the control unit programming: Repeat control unit programming by restarting programming. Connect control unit and procedure for control unit programming using the PIWIS Tester - section on “Fault finding”' Additional instructions for aborted programming Technical Information '9X00IN Additional information if programming is aborted' 3 Select Guest account from the central display (PCM) and activate Privacy mode (available in some countries). Information If Privacy mode is not active, programming may be aborted, resulting in a defect in the central computer (PCM). Central computers that are replaced as part of the workshop campaign are checked by Porsche AG. If private mode was not set in the central computer before starting programming, the costs will be re-debited. 4 Re-program main computer (PCM). Information Intermittently, there is a possibility that the mobile phone will be lost. If this is the case, the customer must be informed when returning the vehicle.
