PA1000 Remote problems

I have the left hand fob type. When I phoned H&P (because my red master fob did not appear to be working) the first thing they did was say "are you sure it's a PA1000? do this test" (they asked me to count the number of flashes when I pressed the fob buttons in a specific way). My answer confirmed to them that I had a PA 1000. But there is certainly more than one vintage of PA1000 because H&P told me to try a slightly different procedure with the red master fob (different from the instructions that were in the car's wallet) - when they worked they said "that's the newer version of the PA1000". But my car is a year older than yours so perhaps the box looked different.ORIGINAL: dommorton No I double checked this with H&P and it's the older larger fobs that have a 12v batt. The later smaller ones have the 9v. Mark does your car have a PA1000 installed? seems odd you have completely different boxes etc to mine? Here's the two types of fob:
Hi again, I've just been out to look for flashing lights on boxes! Can't see any lights but I'm now sure my PA1000 is the black metal box on the passenger side of the transmission tunnel. I can hear a pair of clicks about a second apart coming from that box when I press the "unlock" button on the fob. The plot thickens....
Strange yours is on the passenger side Mark. Most threads I've read and indeed H&P confirmed the location is usually under the drivers seat. I guess being a retro fit UK only system there's no guarantees they'll all be the same. Here's mine. The middle box is the one with the flashing light. I presume this is the central locking controller.
Mine is the fob on the right so that clears up my battery question. Thanks for that. Is the left hand fob a later replacement or was it supplied as original in some cases. Reason I ask is that my car is a '98 registration and as such I would have thought that I had the latest system available at that time. I know that the alarms were an after market fit. Did hamilton and Palmer fit alarms to all the cars, or was the system supplied to the dealer who then did the fitting? This might account for boxes on different sides although if H&P were supplying you would expect them to include instructions as well. There is also a PA2000 I believe but I do not know what the difference are if any. Although I think the PA2000 had a total closure system included, i.e.windows and perhaps sunroof.

They supplied the fobs as per the right for all the PA1000 equipped 993's. The smaller fob came later and is what you're offered when you order a replacement. Much prefer the smaller one myself and not a bad deal at £40.25 all in. The only slight downer of the newer fob is that is doesn't have an LED to tell you when it's working. H&P advised me they didn't fit the systems this was left to the import centre and dealer network to do. They did supply instructions but clearly some deviated from them slightly. I understand the PA2000 just offers the total closure over the PA1000.
Yes it is odd - especially as my car was supplied originally by AFN (the dealer most closely associated with the importer) From your picture: The box on the left is in exactly in same place on my car and I have just looked up its part number from your picture: "Control unit, alarm system, central locking system" (so perhaps this is the disused non-UK alarm, or perhaps it is still used for thecentral locking) The middle box I don't have (except that I have seen something the same behind the left side of the passenger footwell plastic shell) The right hand ribbed box looks exactly same as the box I guessed was the PA1000 under my passenger seatORIGINAL: dommorton Strange yours is on the passenger side Mark.

Well I have carried out some more investigation today and the black box in the middle is definitely part of the PA1000 too. It has a sensitivity trim on it so must be for the interior sensors. Disconnected it and made no difference to the locking. The silver box however is still in charge of the central locking and the interior lights. I can only presume the larger H&P box receives the signal from the fob and triggers the silver Porsche box to open the doors.
So what is your next step? Have you tried moving the aerial cable away from the loom, or playing with its connecting into the ribbed box? Is the "board" H&P talk about inside the ribbed box? Any part numbers on the middle or right boxes?
Hi Mark, No P/N's on the H&P stuff. I have dug out the aerial today and it runs up in to the rear quarter trim. Thought I had it cracked as there was a kink in the loom but looks like it's been that way forever. I straightened it out but made little difference. Having the aerial completely exposed did improve things however. I could reliably lock and unlock being stood right next to the car which I couldn't do before. However it had much better range than this when I picked it up so something is wrong. Going to send off the board to H&P for it to be checked over. If once that's back and reinstalled it's still duff then I'll look into replacing the aerial. Here's some more pics. The infamous Aerial

The Main Board
Hoorah! new board is here and it works a treat! [
] It's not my old board as the bits and pieces on it are different colours to mine. My one also had a wire soldered underneath it which this one doesn't have. The other bonus is that I sent off one knackered old style large fob, one new style but worn and my new one. They sent me back 3 brand new ones and a new master [] Just gotta bolt it all back together now.

Ah seems I have another small issue now. The interior lights aren't working off the door switches [] They work fine when switched across to permanent. Under bonnet light in-op too but engine lid light is working [&:] I can hear the window relay clicking when I open the doors so the door switches are working fine. Have checked fuses 29 and 11 as these seem to be linked to interior lights but they're ok [] I switched them off when working on the car but is there a chance something over heated from me having the door open too long? The central locking controller takes care of the interior light operation too so I hope that's not damaged. I guess the PA1000 could be also linked in to the light circuit and my new board is either incorrectly configured or is worse not fully operational. I did notice those little switches x4 you see on the board are all down on my new one and two were up on the old. I switched these though and it make the alarm throw a fit and the fobs stopped working. Thankfully all was well when switched back.

There must have been some original fitting instructions - used by the OPCs or importer - if you can find a copy that must indicate how it interacts with the lights/central locking controller etc. Although, I guess you have simply unplugged/replugged the new board so that change has got to be related to the board itself - maybe that wire soldered on the back! Bit worrying that our cars a dependent on an alarm system that is not 100% relieable and maintained by the knowledge in one guy's head.[&:]
Don't get me wrong they are a lovely bunch and very helpful when you do get to speak to them. I guess OPC's would have access to wiring info but they are hardly going to share it around with the likes of me. Very annoying but looks like I am going to end up replacing the central locking controller even if just to eliminate it. Guess there is a small chance it has gone faulty whist I've been rummaging under there [&:]
