ECM Programming

  1. If ECM requires replacement, new ECM must be coded. It will be necessary to obtain ECM programming code and immobilizer code from Porsche Cars North America (PCNA) prior to replacement. To obtain codes, complete code request form (Technical Bulletin, Boxster bulletin group 9, number 9801) from nearest Porsche dealer. Proof of ownership (valid title or registration) is required.
  2. Connect Porsche System Tester 2 and turn on. Select BOXSTER and begin control module search sequence. Select DME CONTROL UNIT, CONTROL UNIT PROGRAMMING AND READ OUT CONTROL UNIT. Install new ECM. Select PROGRAM CONTROL UNIT.
    NOTE: During programming, ensure all accessories are off, A/C heater is turned off and battery is fully charged. Ensure all codes are correct before entering. Codes cannot be changed.
  3. Press ENTER. Enter 6-digit programming code obtained from PCNA. Confirm correct entry and press F7. Enter 6-digit code again. Confirm correct entry and press F7.
  4. Enter 16 zeros for old immobilizer code and press F7. Enter 16-digit immobilizer code obtained from PCNA and press F7. Select data record OBD-II CONTROL MODULE and press enter. After confirmation, program will run. After programming is complete, turn ignition off. Turn ignition on. Turn off Porsche system tester 2.
  5. After programming, fault code DTC 108 will be stored. If vehicle is Tiptronic transmission equipped, DTC 100 will also be stored. These codes are due to programming, and should be cleared.
