Also “pedestrian protection inoperative” is displayed on the dash, although not sure if this is related.

Update: this issue has been rectified.

 

The only time that I had seen your first message was when the battery was/had been low.

 

My battery is ok I'm pretty sure. The big issue here is the fact that the pam module is showing as red.

 

I suspect one or a few of those supersonic sensors failed. It is not easy to find which one though. Maybe buy one or two of them and replace suspicious ones and see if any difference.

soneone said I would be able to hear a "clicking" noise from the sensors which are working,
Even if the system is down.

 

I am guessing that your PAM is bad. Can VDash tell you if individual sensors are bad? Most scanners will tell you that.

 

That's my point. V dash won't even connect to the module. There is no communication with it

 

Maybe it's inline. I think you'd probably need full wiring diagram for the car to see how it's powered.

 

Does anyone know we’re the module is located? Maybe I can make sure it hasn’t been damaged/unplugged for some reason.

 

Hi guys. I have a v60 2019 here which is damage repaired. It's 95% done. Issue I'm having is park assist doesn't work, plugged it with v dash and the PAM is showing as red and I guess that means it's offline?

I did repair one parking sensor on the car and re wired the plug as one ripped off in the collision, I was thinking it could be a fuse but there is no fuse for the parking Assist as far as I can see.

Any advice? I am looking to get it plugged up to Vida at some point but just want to make sure all the little broken things are sorted.

I had the exact same issue, changing the support battery fixed it.

 

Does anyone know were the Pam module is located?

 

It's probably in the rear of the car somewhere. Did you look in the trunk area?

 

In the side by the fuse box I found one module which eBay search says is a "boot lid control module"

And another in the boot floor under the first mat which you lift up, which is a "video control module"

 

I don't think either of those would control park assist.

 

Update. Still didn’t solve this. I see a code on Vida “ front back parking sensor supply short to ground” I have done cem reload also still didn’t help.

 

Well there is your problem, you have the power wire shorting out. Chances of it being inside a module are almost zero. Wiring issue has to be fully explored first.

 

So check if any parking sensor is short? There is a harness for 4 rear senors that need to disconnect when taking off rear bumper cover. Not sure if they can be tested individually though.

 

Hi. If it was a specific sensor wouldn’t Vida tell me so? For example “front left inner” Or “rear right outer” etc ? For this reason I’m doubting it’s a sensor.

my car has 6 front snd 4 rear I think, if it’s a case of checking each sensor it’s going to be a long and costly process!!

 

That’s the fault I’m talking about

cem c107a11

ignore the other codes they are mostly sorted now.

 

So it’s either one of the front sensors or the loom? I really can’t believe an expensive and advanced program like Vida doesn’t tell you exactly which sensor is causing the issue!!

 

It is like a bulb is gone on Christmas tree, you have to see it to know which one it is.
Or something tripped the breaker in house, you have no way to know which wall outlet is the problem.

 

Update. I removed the front left outer most sensor (the one by the wheel arch) this is the one that I brought brand new and replaced. Re scanned with v dash and the code has disappeared !!

message on dash has now changed to park assist UNAVAILABLE , service required (before was TEMPORARILY UNAVAILABLE)

to confirm my suspicions I re inserted the sensor and removed the second one and the error came back and did not clear, so the issue is definitely happening from around the first sensor.

I had an old bmw sensor lying around which is exactly the same style as that one so I tried that and it came back with the original error.

could It be possible that it’s the wrong part number causing this? I’m pretty sure it was the correct sensor I ordered originally.

part number 32209364
If someone could double check it’s the right sensor I’m happy to share my vin as I don’t have access to Vida anymore.

 

Can't offer any insight but I recently started getting start stop needs service and Park assist temporarily unavailable. It's going to dealer tomorrow. It was fine parking sensors beeping when parking in garage, and the next morning both errors. I'll let you know what dealer finds

 

I think your issue might be related to the back up battery (small battery under hood)

 

Update. Changed out the sensor with one from the opposite side and fault remains. Definitely bot a bad sensor. Next I will replace the loom

 

At this point, you can check the voltage and current goes to each sensor, and see if it is normal. Also the voltage on the loom when disconnected. If the power wire doesn't have the right voltage, then it could be anywhere from the loom to the controller module.

 

Forgive me I’m not familiar with electronics too much. How would I check these? Could I use a power probe ?
