Pad wear sensor anomaly/fault
Discussion
Riddle me this one then, any guidance welcome.
987S Boxster, however I believe the system has been the same on Porsche forever.
Melted a pad wear sensor (or so I thought) on track a while back, but cannot clear the fault.
Inital fix on the day, (as, I've done successfully before) cut and twist the wires, create a loop. Didn't work - I assumed therefore I must have damaged more than one sensor. Ignored the light for rest of the day, I visually inspect my pads so i know they are fine.
Once home, Replaced melted sensor. No fix.
Checked all 4 corners at sensor connector - continuity OK on all loops. No fix.
Cleaned all connectors, sensor and car side - No fix.
Ensured all connectors firmly plugged in - No fix.
I've no way (outside of dealer diagnostics? Really not up for that) of determining which corner it is, at least as a starter. Any ideas?
Anyway of finding what the resistance across the pins in the car side of the loop should be?
Does anyone know where these loops connect into an ECU or module, so I can check them with a meter at that end? Is there a pinout diagram anywhere?
Many thanks!
