Service Technical Information 52/16 ENU WG30 2 WG30 - Re-programming DME 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. Please refer to Equipment Information EQ1401 for a list of suitable battery chargers/power supplies which should be used to maintain vehicle voltage. Model Year: 2017 Model line: 911 (991) Subject: DME control unit Issue: There may be a difference between the actual coolant temperature and the predicted temperature due to incorrect positioning of the map-controlled thermostat during the warm-up phase on the affected vehicles. The error message "Fault cooling system" will then be displayed in the instrument cluster and the Check Engine light will come on. Remedial action: Re-program DME control unit using the PIWIS Tester with test software version 33.400.020 (PIWIS Tester 3) or version 17.400.020 (PIWIS Tester II) or a higher software version 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 programming. Information On vehicles with Porsche Doppelkupplung (PDK), the PDK control unit is also re-programmed automatically in addition to the DME control unit. Programming time: • Vehicles with 7-speed manual transmission (I-no. 487): 6 minutes • Vehicles with PDK transmission (I-no. 250): 12 minutes 2016© Porsche Cars North America, Inc. AfterSales Jul 6, 2016 Page 1 of 9 2 Service WG30 Affected Vehicles: ENU Technical Information 52/16 Only the vehicles assigned to the campaign (see also PIWIS Vehicle information). This campaign affects 4,365 vehicles in North America. Required tools Tools: • • Battery Charger/Power Supply - Suitable for AGM Type batteries, recommended current rating of 70A fixed voltage 13.5V to 14.5V. Refer to Equipment Information EQ-1105. 9900 - PIWIS Tester 3 with PIWIS Tester test software version 33.400.020 (or higher) installed or • 9818 - PIWIS Tester II with PIWIS Tester test software version 17.400.020 (or higher) installed. 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 starting control unit programming, connect a battery charger or power supply, suitable for AGM type batteries, recommended current rating of 70A fixed voltage 13.5V to 14.5V. NOTICE Control unit programming will be aborted if the Internet connection is unstable. • An unstable Internet connection can interrupt communication between PIWIS Tester II and the vehicle communication module (VCI). As a result, control unit programming may be aborted. During control unit programming, always connect PIWIS Tester II to the vehicle communication module (VCI) via the USB cable. NOTICE Control unit programming will be aborted if the vehicle key is not recognized • If the vehicle 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 vehicle key. To do this, replace the original vehicle key in the ignition lock with the plastic key fob if it was previously removed at the start of this procedure. Procedure: Jul 6, 2016 Page 2 of 9 1 Carry out general preliminary 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 "Preliminary work"'. AfterSales 2016© Porsche Cars North America, Inc. Service Technical Information 52/16 ENU WG30 2 Re-programming DME control unit Information The procedure described here is based on the PIWIS Tester II software version 17.400.020. The PIWIS Tester instructions take precedence and in the event of a discrepancy, these are the instructions that must be followed. A discrepancy may arise with later software versions for example. Procedure: 1 Re-program DME control unit. The basic procedure for programming a control unit is described in the Workshop Manual Workshop Manual '9X00IN Basic instructions and procedure for control unit programming using the PIWIS Tester - section on "Programming"'. For specific information on control unit programming during this campaign, see table below. 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 programming. Required PIWIS Tester software version: Type of control unit programming: • PIWIS Tester 3: 33.400.020 (or higher) • PIWIS Tester II: 17.400.020 (or higher) Control unit programming using the 'Automatic programming' function for the DME control unit. DME control unit > 'Programming' menu >> 'Automatic programming' function. Programming sequence: Read and follow the information and instructions on the PIWIS Tester during the guided programming sequence. During the programming sequence, the DME control unit is re-programmed and then re-codedautomatically. On vehicles with Porsche Doppelkupplung (PDK), the PDK control unit is also re-programmed and coded automatically. Do not interrupt programming and coding. 2016© Porsche Cars North America, Inc. AfterSales Jul 6, 2016 Page 3 of 9 2 Service WG30 ENU Technical Information 52/16 Programming time (approx): • • Vehicles with manual transmission: 6 minutes Vehicles with PDK transmission: 12 minutes Procedure in the event of abnormal termination of control unit programming: Repeat control unit programming by restarting programming. Procedure in the event of other error messages appearing during the programming sequence: Workshop Manual '9X00IN Basic instructions and procedure for control unit programming using the PIWIS Tester - section on "Fault finding"'.
