Digital engine control module DME 7.1.1
Location of DME control module
DME 7.1.1 is a proven, highly reliable engine control module, which was specially adapted to suit Porsche requirements. It is located under a cover in the right-hand part of the plenum chamber (engine compartment) and is protected against penetrating moisture.
Unlike with the DME control modules Porsche used previously, the fault memory is retained even after the battery is disconnected. It is especially important to bear this fact in mind when installing control modules as a test and then returning them to storage or installing them somewhere else. In cases such as this, the fault memory must be erased again before removing the control module.
When the voltage supply is interrupted, the following control module values will be deleted:
- All adaption values
- Learned values of the throttle adjusting unit
- Ready statuses of the individual diagnosis routines (see following chapter)
- Freeze frames (ambient conditions; see following chapter) stored with the faults
Bear in mind that programming the DME (e.g. loading a new data record) will also delete the values mentioned above.
