TCS Toggle Button Not turning off TCS

[Nukem]

So when I click on the TCS button it does not turn off Traction Control. The light doesn't come on on the dash. and if I were to gun it on wet surface Traction control kicks in. My guess is the button/switch is bad. 35300-SL0-A02 is the part number, but it shows up discontinued. Is there anything else it could be causing this? If it is the switch can I pull it apart and fix it? What would I need to do? Or am I left with pulling the fuse for TCS?

Test the switch. It can be taken apart and cleaned as well.

Could be the switch itself but based on what I saw on several NSX, please check the connector housing of the TCS switch.

Due to the limited space, one can pull out just the housing when trying to release the mating connector.
If this happens, you can still fully lock the mating connector yet the internal terminals won't make good contact resulting in open circuit.

Make sure the connector housing is fully seated against the circuit board as per left side of the 1st photo.

2nd photo shows that the mating connector fully locked even with the housing pulled out away from the circuit board.

3rd photo showing that if the housing is pulled out, the terminal on the circuit board won't make good contact even when mating connector was locked in place.

I would have never thought to even look at that, but will check that when I get under and look. Thanks.
