Ugh. The worst news I have received in a while - even though I still appreciate your input. :)

Arent BeCM problems indistinguishable from fusebox problems? I mean if the fusebox is playing up, wont it cause the BeCM to do funny things? I realise that you seem to know what you are talking about, but is it worth checking anything else to rule out dependencies?

I hope not, but this could be a death knell for my P38. If the repairs/replacement of the BeCM run into more than many hundreds, then I wont be able to justify the expense - my love affair with the Rangey will have been short lived and brutal. The risk I took spending all the money I had on the original vehicle doesnt seem to have paid off... [bawl]

I have an additional admission. When I was troubleshooting the immobiliser problems, I disconnected and reconnected all of the accesible BeCM plugs to ensure that they had a firm positive connection. While disconnected, I gave each one a quick spray of electrical contact cleaner from Jaycar. When I did this, I dont think I had the battery disconnected. Is it possible that the spray is causing issues on the BeCM connectors or is that a pretty safe practice?

Time to shine the big bat light into the sky and call for Andrew e (Andy) to see if he has a donor BeCM at the moment.

If so, you should be able to solve your problems without losing the farm...... or the Rangie

Contact cleaner is not conductive, the risk is that it is flammable if you produce a spark on reconnection. Didn't happen so that's safe.

More info is at hand. When I tried (in vain) to synch my fob with this procedure that I hadnt seen until now, I noticed something.

The RR is sleeping peacefully here at work, but when I use the fob button and watch the gear selector light she wakes up. All that proves is that the receiver is working (which I knew from voltage tests) and that the BeCM is receiving some kind of signal from it, however no doors lock or unlock. It was an interesting observation to me since I was able to test the transmitter, recevier, wiring and connectors with one easy step. Might help someone in the future.

I can certainly understand where you are at.....

You put the key in and press the button just one more time.... clutching to the desperate hope that this time it will work and all the worrying was for nothing.

You know that its probably not going to work, but that doesn't stop you having one more try....

I am not taking the **** here, I genuinely know how it feels. There are so many different remedies documented that you cannot believe that none of the simple ones will work.

Keep us posted.....

have sent an e-mail to Glen, but it might be better/quicker to ask here...

Rupert - will a BeCM from a 1998 P38 be a suitable donor for Glen's?

If so, Andy has one he can send you.

Cheers, Paul.

i will have to check as yours is lucas inj and his is bosch inj but i think it will work as long as it is a highline unit (faint capital H by itself in the lefthand corner of the paper sticker above the fuses). i will check the wiring diag tomorrow, i can`t remember the difference but i think i can just change the programing. the part number would be handy as well (paper sticker again).
it would still be worth trying the hard reset again, perhaps try powering it down overnight.also the key resync in the handbook on that model is wrong it is the same as all the others, lock and unlock the door with the key while pressing the remote buttons.

Cool, thanks Rupert.

I will pass your phone number to Andy and ask him to give you a call when he can check the BeCM for the info you requested.

Agree about the hard reset though. My previous 95 P38 needed a reboot every few months... the engine would start fine but no electrics and all the lights would flash.

Current 99 P38 has been well behaved by comparison. Only had to reboot once when I thought the fuel pump had died. Disconnecting the battery for a few minutes can work wonders.

Cheers, Paul.

Just WOW... For your sake Glen, I hope BeCM replacement therapy works the treat!

If it makes you feel better, I've heard what you have many times regarding the key re-sync. According to a few sources that i've read, it should do it all by itself. I had a similar issue to you when my previous P38 went for an interior wash in a creek a month ago. I didn't use any special procedure to get it all going again, had the alarms and everything you did too, simply unlocked the car and put the key in and she was all good! Except the minor problem that was the car didn't run on all 8 pots and ended up being written off...

I feel your pain (to a degree) and hope that it all ends up working fine for you mate!

Gotta give a big cheers to the help you're seeing on the forum here - how lucky are we to have such knowledge and advice at our fingertips! And help is only ever a phone call away for most people here!

I know a certain lad who helped me out immensely even though I am from Cane-toad territory and he's from Gillard's new office (thereabouts). If it wasn't for this forum we'd all be stuck!

Cheers

I know - in fact, without lurking here before I bought a car, having had a mate with one, I wouldnt have ventured down P38 alley. I am extremely grateful for this resource, local too! I would really feel pretty helpless without it. I hope to be able to gain enough nouse to help others in the future.

I sure will. I meant to have tried it before now, but I have been running around a bit crazy. I will get onto tonight and report it. I am more hopeful then I should be ;)

On a similar note, last night I made some more final checks. I got access to the BeCM earth and what do you know, I could turn the earth wiring connecters (3 of) with my fingers easily. I reckon there was still a connection, but I took them off, sanded them back a little and used electrical contact cleaner on them and retightened (using Arnie strength).

This -IS- interesting news. I will try it today. Dumb questiopn: Does that mean holding down both buttons while locking and then unlocking, or holding lock button while locking and then holding unlock button while unlocking? I also assume the key stays in the lock throughout this process?

Thanks Paul, got your phone message. I sure do appreciate it. The AUD is strong right now so access to Yankee BeCMs is good, but I would much rather support this local group. After hard reset and more stern words to Rangey Stacey I will contact you.

I felt better reading this post. Thanks David. It is good to know that I am not the only one doing these strange dance moves and incantations ;)
