parktronic sensors troubleshoot?

Is there any way to troubleshoot individual parktronic sensors?

I don't know. I can tell you how they work and that might help.

The front sensors monitor:

The space about 1 meter away

The rear sensors monitor:

the space about 1.8 meters away

In forward gear, the rear sensors are deactivated.
In reverse gear, all sensors are active.

The ParkTronic System control unit carries out a self-test when the ignition is turned to the RUN position. All the LEDs light up, then go dark if there's nothing close enough to trigger a sensor.

... so knowing that, and because I can't resist guessing:

You should be able to trigger each sensor individually, on demand, if you can avoid detecting yourself; maybe fishing pole, some line and a hook with piece of cardboard dangling - or maybe just a wooden dowel with a string taped to it, dangling something that'll be seen by a sensor - so you can verify an individual sensor is working?

If you can find a suitable scan tool like Chrysler's WiTECH or Chrysler's StarMOBILE or MB's Star Diagnosis System (SDS) than you should be able to watch each sensor by looking at the PTS (or whatever MB calls it) electronic control module.

That's a great idea on testing Jon.

Also Jon do you know if the rear parktronic gets disabled if it detects a trailer plugged into the harness at the back or not.

Thanks

Chrysler docs don't mention deactivation with a connected trailer.... makes sense though.
