Engine Disabled - AGAIN!

P38 DT 2000 model. On 3rd january car wouldn't start, engine disabled message came up. Tried EKA code several times, no luck then 3 doors and tailgate all superlocked only drivers door would open with key. Bought new heavy duty battery put new batteries in fobs, still wouldn't start. Sent Becm off to have immobiliser disabled also sent ECU off to have immobiliser facility removed. Bought new RF receiver from Island 4x4. Got everything back and car started, all doors unlocked, great, no more problems now, car been running great. Today wouldn't start, engine disabled message came up and red alarmed light flashing. Tried EKA code, no luck, used BeCM synchmate to see if key had lost its code, still no luck. What is going on with this car, only done 88K and great car otherwise. Suggestions please, getting fed up throwing money away.

hi please see your messages ,regards mozz

This sounds interesting.

The immobiliser cannot be removed from the becm, & the engine ecu hasn't got an immobiliser.
Who did you send your becm off to?

There's a few guys who can unlock a becm, but have no knowledge of them whatsoever.
Who done your becm & ecu then we might be able to work out what has gone wrong!

Speak to Mozz-an absolute gentleman!

Think it may have been www.youv'ebeenconned.com.

WAMMY your so fecking sceptical ..ha ha ha actually the becm was done by turners ????????? so dont know what theyve actually done but will get confirmation today ,,and will be trying my potion later ,,,will let you know cheers mozz:crazy_driver:

As far as i am aware you can disable things but not remove them. ECM does not have a disable function. It has an embedded code the BECM has to read which has to match the code stored in the BECM before the BECM will switch engine systems on. If the ECM is set robust (BECM needs code) it cannot be set to none robust (BECM does not need code). Even T4 and MSV extreme can't do that. Once set to robust that is it. So it will always need the sync code. EKA and engine disabled in alarm can be played with, (disabled) but not as far as i know removed.

Exactly

Hi Guys, thanks for your interest in my predicament. In january the engine disabled message came up and the car wouldn't start, I bought a new heavy duty battery and new batteries in the key fobs. I checked that the EKA code I had was the right one, tried several attempts with the EKA code but no luck. I called out a local LR dealer, he came with a laptop and all he could say was that the doors were locked and the immobiliser was on which is what I already knew! I saw an advert by Bell Auto Services,York, that they could remove the immobiliser from the ECU so I took it to them. I then found out that the BeCm needed to have the immobiliser disabled so I sent it off to Turner Automotive. I also fitted the new RF receiver from Island 4x4 and when I got everything back and fitted the car started no problem and all the doors unlocked. The only problem was the key fobs did not open/close the doors, I had to use the key to get in. Everything has been fine until the other day when the engine disabled sign came up again and I had to get my car brought home on a recovery truck. Mozz Smith has been in touch and very kindly talked me through several procedures to get the car going but so far no luck, he thinks it could be either a faulty micro switch in the door or the key has lost its synchronization somehow. A local LR expert is coming on wednesday with his diagnostics so I hope he can fix it. After I had spent all that money after the last breakdown I thought it would never happen again. Anybody any suggestions please.

I know Turners. I've done Becm's in the past for them & stopped when they kept asking for the Binary values. I refused on the element that a little knowledge is dangerous.

Wammers & Datatek, You're spot on with that info.

Mozz, I take it you're on commission?

hi rick , i wish i was on commision ???????? ive basically re-sync over 90 cars over the phone over the last 3 yrs ,, the very low percentage i.e. 6-7 that ive not been able to do have in my opinion LOST the sync from BECM --- ENGINE MANAGEMENT SYSTEM this has to be done via nanocam --faultmate --autogic ,,etc i know this as having told the owners to get a diagnostics kit ie the afforementioned to re connect ,then they have all done this and their up and running !!!!!!! i have also had a couple of failures cos they were diesels WHY that makes a difference ??? i dont know and cant work that one out ..any ideas ?????????. i also am aware that sometimes the microswitch in drivers door has failed i.e. fckd and told to replace ,,? i believe there is 2 switches in the door both microswiches being green ??????? can you confirm that ???? and wich switch it would be ???????? this would be most helpfull . cheers rick i appreciate your valued expeirianced imput ,,as others have said the becm cant be set to delete the immobilisor or alarm system ,but can be re-enabled when superlocked correct or not ?????? i can pm you with my no or you can pm ,me with yours if you want a chat ,,,once again many thanks rick cheers mozz

Hi Mozz,

There's 3 micro switches housed in the drivers door lock mechanism. It could be any one of them. A quick dismantle/clean/service usually does the trick 50% of the time, & the other 50% there's evidence of door lock failure.

The fact that the becm has been sent off, & the fact when it was refitted everything was normal except the keyfobs & you've been running for nearly two months points me directly at two possible issues.
The first is, These becm's are a complex piece of kit. A few people have the software to read & program, & advertise as becm repairers, when in fact, they are just programmers. If the becm has a sinister problem & this in turn places the becm into an alarmed state, ie: Keycode Lockout, & by getting the becm reset allowing the car to unlock & start doesn't mean the problem has been fixed. When the becm enters the alarmed state of Keycode Lockout, this is an action resulting from a primary problem.
Data will get corrupted. A serious problem will corrupt & deactivate the EKA code, & one in three will lose the fob code, Hence the fobs not working.
These codes can be replaced & the becm reset, but the primary problem will still exist. Reverse engineering the fault to reveal the problem is where the experiance knowledge & skill are needed so when the becm is returned the integrity of that becm is 100%.
I brought this up a few months back after that huge post with the other chap who was supplied a becm that didn't work.....
That becm can be sent off to be reset umpteen times & it will still go into an alarmed state, deactivating the EKA code all the time the primary problem exists.

Moving onto the door lock & this is where it can start to get expensive, keeping in mind the becm has been done & paid for, & the only way to be 100% certain is to replace the door lock mechanism with a known working one or new. If that's not the problem then it's back to the becm i'm afraid.

Has anyone looked at the under bonnet fusebox?

Hi Rick-the-Pick, just checked all under bonnet fuses and all are ok except there is no 50amp Maxi fuse in position 2, there wasn't one there when I bought the car last June. The car is in an alarmed state all the time and won't recognize the EKA code at all, I have removed the horn fuse and disconnected the alarm siren to stop them going off all the time. I am cleaning wiring connections in the drivers side footwell and front door just in the hope there is a bad connection. Thanks for all your help guys, really appreciated as I am more of a spanner man and I'm not good with electrics.

Mine does this on regular occasions funny enought it's in the same places every time. New batteries in fob . Luckily the secret code always works but I am all ways quite ferm when doing it

Thanks Rangeyroamer, when it became immobilised on thursday I was miles away from any radio masts or anything giving off electrical interference. The car had been running great then this happened out of the blue so to speak

Something has upset it.

I'd like to investigate your becm & see what's going on inside there, as this is where I'm approx 75% certain the problem is festering. The door lock issue needs to be sorted out first & I assume Mozz is sorting that for you, although i'm not certain.

I also assume the fusebox has been looked at, earths & associated wiring.

Well looks like the Butler is letting you down, time for a replacement?

Wish I could afford a Butler, I,m just a retired ex trucker who is forking out too much cash to keep his rangie on the road. I've checked all fuses and connections as far as I can, the carpets are dry with no leaks etc so no water in the electrics. I've got a local LR expert coming round on wednesday with his diagnostics so I hope he can shed some light on the problem so I should know then if the Becm needs to be looked at. Thanks for your offer Rick-the-Pick, I might take you up on that. Thanks.
