Hi there,

I am having issues with my brake lights not coming on and I would like to know how to test the brake light switch for this unit or is there a way to bypass the switch to test it that way?

Cheers

Yes you can remove it and test it with a multimeter. Post a picture of the switch if you need help with that. 

To be honest I would just replace the brake light switch if you suspect it is the problem. While they do fail the good news is that they are cheap. 

It is a hall effect switch, but I think you are right...just replace it and see if that makes the difference.

 

Thanks for your help...I appreciate it ;-)

try to place sensor on one of two wires and keep holding the brake pedal down as you do so. Other wire can be tested then. The test bulbs will illuminate, if power is connected and switch is working fine.

So I replaced the brake light switch and now it’s working fine. Apparently you cannot test this part...I also found that the drain for my sunroof, which runs down the front of my car right by the LCM (light control module) was leaking inside the car and thusly my LCM was completely frozen. Let it thaw and all was working well. Not sure now if the brake light switch fixed it or the thawing process fixed it, but it’s wirking great now...thank you for your help. Cheers and merry Christmas ruth
