W213 hood switch




This cast the doubts back on the 2x separate GND posts, likely up for maintenance.
Locate sensor GND posts: W15/5; W16/3
When these GND inputs go missing, the F-SAM gets an "open hood" signal.
Other circuits sharing these GND experience random disruption in their own ways.

Anyhow, hands-on time to test faults never goes out of fashion.
