Disabling PDC
 

I must have a bad connection on one of my pdc sensors, as it gives a solid squeal as soon as I put it into reverse (everytime).

Is there an individual fuse I can pull to temporarily disable only the PDC until I can have a look?

Thanks.

I'm not sure if there is a particular fuse...but there should be a fuse index in both locations that are mentioned in the owners manual. The fuses in the glovebox should have a printed fuse index when you pull down the door that exposes the fuses...and the rear fuses should have an index on back of the compartment door on the right rear side in the cargo area.

The fuse indexes list the fuses alphabetically, plus illustrates their location within the fuse box, as well as the amperage for each fuse. In this case...look in the "Ps" for some type of mention for PARKING:

If you find there's no fuse for PDC or "parking"....then there's the PDC control module which is on the left side in front of the vehicle's battery which is below the floor panel in the cargo area:

check fuse F6 - it will also kill your electrochromatic mirrors and either the adaptive headlights or the RDC, depending on which options you have...

Fuse F6 is in the glove compartment

One check to see if a sensor is bad is to listen to it. If you activate the PDC system and put your ear close to the sensor you will hear a distinct ticking. Listen to them all and if one seems different then that one may be the issue. If you can get your hand up behind it, check and seat the plug connection. This how I found the sensor that was throughing a code for mine. You have different symptoms but this is so easy to do and may help you find an issue.

I had that problem after I took my car to the car wash. My guess was one if the sensors was covered in wax so I tried to clean them with window cleaner and that didn't work, so I ended up spitting on a paper towel and rubbed them a little and problem solved

Great, thanks guys I will try to troubleshoot first before having to disable.

what if none of the sensors is ticking?
i check the supply going to the PDC module and there's 12V (i think).
module is kaput?

give us more symptoms of the problem... :popcorn:

Basically same as the BBQ ...
just a solid beep once you engage to reverse or manually pressing the PDC button.
Fuse is ok, supply at the connector right at the PDC is OK. none of the sensors tick once activated as suggested above.

Cheers!
