2470 DME Control Module

With all DME systems, the engine must run for several minutes before the engine control module can relearn the idle speed and mixture adaptation values!

After disconnection of the power supply, the idle speed might change or fluctuate briefly until the throttle valve adjusting unit has been readapted.

The mixture adaptation is also lost.

After the battery is connected: 

With the DME, it is necessary to carry out a learning and adaptation routine as described below:

• Switch ignition on for 30 seconds without starting the engine. 
• Do not actuate accelerator pedal. 

This completes the adaptation of the throttle valve adjusting unit.
