As well as looking at the fault codes in FORScan, have a look at all the PID's relating to the Parking Sensors/Module. they should be in either the PAM Module if that is showing or the BCM or both. Use the search function.

You should be able to see Live Data from the Sensors and given that the system did work for a while it may be a wiring or connector fault.

If you do get Live Data up then give the wiring and connectors a wiggle test while someone is looking at the Data.

Thanks buddy will give that a try

After clearing the DTC's, there are no fault codes relating to front sensors but they are not working.

Thats very strange. Especially as they worked for 5 minutes after you fitted the replacement module. It's starting to sound like the wiring to me. 

On the focus there is a big plug under the near side headlight where the front sensors and fog lights connect. I'm unsure where this would be on your Galaxy, but its worth finding this plug and cleaning it up giving a good squirt of WD40. 

It might also be worth looking at the plugs that connect to your module and seeing if theres any signs of corrosion....and again, a good squirt of DW40.

Thanks mate will try the above advice, is it safe to spray WD40 in the sensor connector blocks (pins)? by the way I've just tried spraying WD40 on the front sensors, but unfortunately no luck.

I will also try getting live data from forscan RE front sensors. I'll try to make sense of it but I might need a bit of help understanding the data.

WD40 will displace any moisture that's got into the connections. Given you've had short circuit faults and the wet weather we've had lately, I would of thought this was the most likely that water has got into one of the connections. 

The other thing to note, is that there are three terminals to each sensor. A live, an earth and a signal. The live and earth are all linked through all of the sensors and the signal comes back from each individual one. If you have a fault on the live, then it's very difficult to diagnose which one is giving the fault as they are all linked. 

In forscan you can monitor the sensors individually for the range they are picking up obstacle. So monitor the sensors to see if any are giving an obvious wrong range reading. Walk past sensors one at a time and see if the range changes.

Thank you guys, I appreciate the help, I will definitely look into the suggestions made by you guys. I'll be bk😊

See, this is what I like about this forum......inbetween the 'Stop Start not working' and the "Sync 3 unable to update" there are nice little nuggets of information like this.

An easy way to find to the parasitic battery drain on my focus, for starters. I'll also have those lotto numbers, but give us the euros as I dont want to share it with @unofix!!!

I could tell you but the money would ruin your life as it has others. I wouldn't want you blaming me . Same goes for the others asking. 🤣🤣🤣.

 Hi guys, hope your well? Took both your advice. 

1st used the WD40 method. I sprayed the sensor's and the module pins and connectors to module. No difference. 

2nd I got live data from forscan, plz see pics. The rear sensor numbers decreases, but the front sensor numbers do not change when I walk past.

However if you look at the data some front sensor data boxes say inactive and not configured.

Sorry but I can't understand what that means.

I also checked if there's any new DTC's again. No DTC's. 

That looks to me like the front parking sensors have not been activated.

Would the front sensors have to be activated within the replacement parking module? Or would this be an option within BCM?

What I'm confused about is, I'm sure they worked for a couple of minutes when I swapped the parking module. (Unless I was Soo excited,I was hearing beeps 😂 )

How can I check to see if it is configured or activated? 

Check the settings in the BCM for the sensors. Check front senors have been selected and set to active.

Ok thanks I'll check and let you know.

Hello guys, I've finally done it. Got the front and back sensor's working. It was a long slog but with all your help, finally got it working. Using Forscan, went into the BCM module and tried the different options on the parking assistant option, when I changed the settings to front and rear parking only, it did the trick. Just like to say thank you to all of you guys, for all your help. 

Hi - I have been experiencing the same / similar issue to this post and thought it might help others is providing my experience. I was getting the single warning tone when selecting reverse indicating that the parking sensors fail (Galaxy 2008). As above thread, I bought an OBD2 ELM327 V1.5 USB reader off ebay (£5.33) and dowloaded Forscan. This give me 2 diagnostic codes Front Sensors Power Circuit - Circuit Short to ground & Rear Sensors Power Circuit - Circuit Short to ground. I removed all the rear sensors as these are relatively easy to get at - reset PAM module and got same errors. Found the PAM module at right hand rear behind lights and disconnected the plugs connecting the sensors. Reset PAM again and I now got different 9 errors in total - General Electrical Failure x8 & Front Sounder which is understandable.

Plugged in the rear, Reset PAM and now got 5 errors Front Sensors General Electrical Failure (front cable wiring unplugged). I had connected back the rear sensors and was not getting any errors which was encouraging. Plugged front sensor cable back and got the original errors Front / Rear short circuit to ground! This led me to think that there was a problem with the module. However disconnected the front sensors (at least the 3 within relatively easy access) and retested. This gave me individual errors for the front sensors and rear sensors were not error. Replacing front sensors one by one cleared relevant error - until went back to the 2 original circuit short to ground errors. I replaced the front sensor with a new one and hey presto all working! 🙂

Quite why the module reported both Front and Rear Sensors Power Circuit - short to ground, I don't understand - it was only a problem with one of the Front sensors!! Hope this helps anyone else with this issue.
