I'm trying to chase down the absence of cruise control in the new ride. Starting with the switch test in VCDS, I used measuring block 066 to check all the switches as per this write-up:

http://wiki.ross-tech.com/wiki/index.php/Checking_Cruise_Control_using_Measuring_Values

Everything passed except for something odd with the clutch switch. According to the write-up, the clutch switch bit should be 0 when, "clutch not depressed" and 1 when, "clutch depressed."

My clutch switch shows the opposite. The switch is changing when I push the pedal but it reads 1 with the pedal up and 0 with it pushed in.

The switch was replaced earlier by the PO for another issue but it turned out the switch was unrelated. The stalk switches all register fine and the brake switches both set the right bits. I'm not throwing any codes for implausible signals from any of the switches. Otherwise the car seems to be running fine.

It's a MY2001.5 6MT car.  At one point it was running phila_dot's map switching bin from this thread:  http://nefariousmotorsports.com/forum/index.php?topic=2872.0title=  It's currently running a jfonz stage 3 base tune. 


Three possibilities:
- The switch is working properly and the documentation is reversed
- The switch is reversed and nothing else is affected.
- Something in the tune is messing with or ignoring this bit.

Does this seem like the clutch switch could be the culprit or is this a red hearing?

Otherwise, does anyone have any ideas what to look at next?

*Thanks*

This is definitely plausible.  It looks like this being wrong would have other effects though, or is that only on older models?
 

The current switch trips when I barely press the pedal. 

Regardless, I think that the reversed switch is confirmed.  I pulled the connector and jumpered the connection to flip the bit.  The cruise control now works as expected.  Strangely, nothing else seems to be affected by this.

Infinkc is the PO and he still has the original switch which turned out to be fine.  He's sending it my way to confirm the final fix.

Thanks for helping confirm that a reversed switch is even possible.

This actually makes sense if you think about it.

The starter switch is there to prevent you from starting the motor unless the clutch is all the way down.

The intent of the other switch is to disengage the cruise control if the clutch moves at all..
