Pulse Generator - Cylinder Reference Point

Check function:
[M] 22 - Connect oscilloscope connections at component connector and run engine at idle speed. An alternating voltage characteristic curve with positive and negative half waves should appear on the display screen.
Switchover to semisequential injection takes place as soon as the reference signal is detected during normal operation. Only parallel injection is possible during diagnostic mode.

Resistance test:
The resistance can be measured directly at the component connector (at the connector strip for injector valves). For wiring diagram, refer to schematics.
