Hood Open warning

I have a CL500 2003, 5Ltr.

As I move off I get the red "Hood Open" warning on the dashboard.

The microswitch under the hood latch is performing fine, no problem here.
It is closed-circuit when the hood is open, and the microswitch is open-circuit when the hood is closed.

I have disconnected the microswitch altogether. Which leaves this sensor disabled/bypassed, and so I should never get a warning.

To be sure, I also disconnected the connector at the front SAM (connector has two wires, one brown, one brown/red)

Problem is that I still get the warning on the dash continuously when I move off.

Any suggestions on how to further investigate this problem would be much appreciated. Not getting any feedback on CL forum, thought I would try a wider audience.

Tks Peter
