Check function:

•M• 22 - Attach connections for oscilloscope at the component connector (adapter: Cartool 61 1 491) and operate engine at idle speed. From the point the engine starts, an alternating voltage characteristic curve with positive and negative half wave should appear on the display screen. If no signal is applied, the DME control unit cuts out fuel injection.

Resistance test:

The resistance can be measured directly at the component connector (at the connector strip for injector valves). For wiring diagram, refer to Diagrams / Electrical. For technical data, see - Technical Data -.
