| Parking Module - Require Coding? |
|
Hi All
been having some issues with the PAM on my D4 and I've been living with them for a year since I've had the car now. The sensors kick in (or at least you hear the initial beep) when you put the car in reverse. However the actual sensors don't work in that the sounder doesn't sound when getting closer to an object. So I replaced the sensors, or at least the rear ones. For clarity, neither the front nor the rear sensors have ever worked.
I have also replaced the Parking Aid Module (found behind the passenger side rear quarter panel). I've checked the live values and it shows 2.6m and no faults on the IID tool. That is, with a replacement Parking Aid Module from a donor car of the same year (2010).
The interesting thing is that if I connect my original one in, it shows a number of errors on the rear sensors... and this is true with replacement new rear sensors too. What's more is I have checked the wiring from the connectors at the Module, back to the connector behind the tail light (passenger side), and then onwards to each of the sensor connectors - all seem fine. The loom doesn't look damaged either.
So in summary:
With the old module connected I get no sensors working but errors on the rear ones ( I will do another fault read and update this thread).
With the new one connected, I get no sensors working, but no errors.
In the CCF interestingly it has both rear and fronts selected under the config, but in fact it shows two 'configs' - one says 'Config (2010-11), and the other says Config (2012+).
Does the parking aid module, if replaced need coding to the car?
Any help appreciated, parking this car without sensors has been most challenging!

As per the pinpoint tests in the vehicle workshop manual…. did you test your battery first? 2015 LR4 HSE Lux Aintree Green
2013 LR2 HSE Radiance Red
2007 XKR Jaguar Racing Green
2005 XJR Jaguar Racing Green
2002 S-Type R British Racing Green

Yes the battery is good it's also just a few months old as I replaced the battery.

If you’ve replaced the sensors and the parking aid module and still have issues, the only remaining possibility would seem to be the loom section in the bumper. These are a known problem area, and even if it looks fine all there needs to be is a tiny internal short circuit to cause all kinds of chaos. I had similar issues on my old D3 and in the end it was the loom at fault.
I hate to suggest firing the parts cannon again, but that seems to be the only original component left!

Thanks scarecrow for your input, appreciated 
I did check the loom on more than one occasion. Having removed the rear bumper and the harness connector, I did a continuity test from each of the three pins back to the connector and they all checked out good. I further traced back from the connector to the parking aid module, again all continuity beeps were present.
What's also strange is that one of the front sensors shows a fault, but none of the other three front ones work either?
Do the front sensors rely on the rear ones to be working as a pre-requisite?

I would be unplugging the front bumper loom, (remove the drivers headlight and you will find the plug), this prevents any shorts on the power wires
Fit your old ECU
Then edit the CCF, to say rear sensors only.
Test & read codes
Keep going at it, and get the rears working first.

Thanks Pete - when I contacted Patrick over at GAP, he told me that I should leave both the config's enabled. But I take your point on board.
So basically, disconnect the front loom (could I do that the parking aid module instead - is it the same thing?), therefore isolating the front loom, and focus on the rears.
thanks for the encouragement too, I've been at this for nearly a year on and off now, and almost at giving up point.. that said - I managed to fix a similar issue on my previous D3, so will keep at it!
