Hi, when I bought my 02 boxster the parking module was disconnected. I connected both plugs and got a steady tone when in reverse - hence why they were disconnected.
I get the same symptoms with either both plugs connected or with the parking sensor plug disconnected.
I did a quick resistance check from the sensor plug and got an open circuit across every combination of pins. I am not sure if this is indicative of my problem as I do not know what values I should see across the pins.
Can anybody help with what my next diagnosis should be?
Where is the connector break between the park assist module and the sensors? I looked behind the carpet trip in the rear hatch - nothing obvious.
Thanks
Simon
