Rear Parking Sensors

[ferrytrip1]

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 step in the 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

The easiest troubleshooting will be to read the fault code(s) for the ParkAssist system. You will need Durametric software, a Porsche PST2 tester, or Porsche PIWIS tester to read these faults.

Thanks - If i ever get any of those I will give it a try

Without one you are looking at a lot of meter work (ohms and volts) and you can not test the control module.

Yeah, understand, happy to do this until I find a decent repair shop with this equipment.
