Purchased a replacement switch, got under the dash (my back is not happy with me) to do a trial run before actually replacing it.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

As the title suggests, I had the PMS/ABS lights on the dash and alerts on the screen for a month or so on my 02 4S. Purchased a replacement switch, got under the dash (my back is not happy with me) to do a trial run before actually replacing it. I was able to twist the current switch, which is what I was trying for. Was planning to go back in the evening to run the full install. Twisted it back in place and took the car for a drive. PMS/ABS lights off, brake lights operating as they should. Did I fix this just by readjusting? Has anyone else had this experience? Thanks!

POST 2Original post

The plunger on the switch is adjustable for length. Pull it all the way out before installing, then pressing the brake pedal will set it to the right length. You may have pulled it out (lengthened it) while you were fiddling about down there. If so, and if the problem really was that the plunger was too short, you certainly could have fixed the issue.

POST 3Original post

There is a spring inside the switch that can fail, causing intermittent problems. The switch is pretty cheap, if it acts up again soon, just replace it. if you remove the switch, verify the plunger moves smoothly, and doesn�t stick in the depressed position�� -Eric
