Now just before I call for the tow truck and get my 98 4.6 HSE Japanese import to the independent I was hoping for a final input from the forum to make sure I haven’t missed anything……
*
Changed the batteries in the only remote keyfob I have and lost synch.
Tried to resynch no luck. Confirm keyfob is transmitting RF with spectrum analyser. Operates on 315 Mhz.
Engine disabled
Checked with local Land Rover dealer and he says they have no EKA code for my vehicle not used on Japanese models
Just in case I try the default for NAS vehicles 1515. No luck goes straight into keylockout after the first attempt. However I can see from the sidelight indicator lamp on the dash that it is registering the input of the EKA
Breakout the Faultmate MSV
Determine that BECM is locked and use the disarm function with both 1515 and EKA n/a. No luck straight into key lockout. Sounds as though it is resetting relays etc and confirms that it has instructed the BECM to reset but no change.
Consult forum and internet.
Check all doors, bonnet, boot etc operate interior lights correctly.
Leave key in position II disconnect battery. Leave 30 mins reconnect no joy.
Power Faultmate MSV from independent 12volt source and jumper fresh battery across RR battery to ensure no issues with low voltages. No change.
*
Anyone have any other suggestions before |I get the local indy to try and reset it an finally unlock my BECM?
*
Thanks in advance.

This may be of no use... and not having a faultmate, I'm not sure if it's possible... but...

If you can get into the BeCM and try to reset it, then will it let you program an EKA into it? or is that function only part of the BeCM unlock module that's extra?

If you do have to get it taken to the Indy, then if they put it on their diagnostics to unlock it, then is it worth asking them to program in an EKA for you - then at least if it happens again, then at least you'll be able to use EKA to get going...

Where abouts in NZ are you?

Yep, BECM locked so I can't get access to program in an EKA. Hoping the Indy can unlock for me.

In Windy Wellington.

I was born down that way - and still have a lot of family there! Sadly though, when I had my P38's, I was living in Auckland, so don't know who the best indy is down that way!

Good luck getting it sorted!

Cheers,
Marty

If you have got "KEYCODE LOCKOUT" it will normally lock you out for 30 mins before you can attempt to enter the EKA code again.
You can use the Faultmate SM022 module to enter the EKA code directly or even switch off the immobiliser.
If you make too many attempts at the EKA code without waiting, the BECM can spit its dummy out and go into an alarmed state. You then have to get it unlocked using SM035.
If you have a registered Faultmate go onto the Blackbox Forum for more information.
You can get help finding someone in NZ with SM035.

OP: Instead of having your rig towed for a simple unlock why not remove the logic board form the BeCM yourself and send it off? No sense incurring a tow bill for a repair that weighs less than 2 pounds. If you have a local source for unlocking you can drop it off. If not I would contact Rick the Pick to get the contact info for his BeCM guy in Australia.

So....Indy collected the car and tried to unlock the BECM (still hadn''t found someone in NZ that can talk to teh BECM directly at that stage) no joy. Removed BECM and found evidence of water damage at some time in the past. Also on the logic board one component has clear sign of damage with a microscopic hole in it.

Have now found somebody who can unlock it all for me but I'm wondering now if it is now fit for purpose again with the existing component damage. My logic says no but new replacment is expensive and would a secondhand be any better? Secondhand ones do not seem readily available in NZ.

Any advice welcome!

Suggest you have a word with Rick the Pick (Callrova) who is a forum member.

He specialises in BECM repairs and is located in the south of England.

Hi Norman,
I have past week nothing els done then measuring of BeCM's
There is a connection between 2 wires that disable the BeCM out of the starter cirquit
Connect at the BECM wire 6 at conector C1282 (99-2002) or C257 (95-98) White-Red with wire 2 at connector C1278 or C113 also White-Red
These wires are ground signals not power.

This way you get round the EKA code

there's a bit more to it franc143 if your trying to fool the BeCM it can detect unauthorised cranking and immobilise the engine as far as i understand it.

For any one who might be left still following this saga....

It looks to me like a surface mount capacitor, diode or resistor has popped and there is also an area around one of the ribbon connectors that looks as though it may have got a little warm. From the verdigris on the bottom of the power board it does look as though there may have been some water in there. Also it looks as though the solder joints on the big cables connected to the board may have been re;flowed (flux on board)



Would really welcome any guidance on whether or not this BECM is beyond economical repair. Should I try to get it unlocked, set an EKA and give it a whirl or do I need to dig really deep and get a new one…..?


Thanks for your advice.

Send the logic baord pictured to someone and have it cloned. Install the new one yourself. It really is not as big of a deal as everyone fears.

If you haven't already, then get in touch with rick-the-pick here in the UK. From other BeCM threads I've seen he is the person to talk to. He may know someone a bit closer than UK (maybe OZ) that you can send logic board to, and they can look at it and either repair or clone it for you.

I had BeCM issues with my 1995 when I was in Auckland - someone prior to me owning it had replaced the jukebox, and pinched one of the main +ve wires to BeCM between fusebox and chassis... sparky sparky! Caused all manner of problems! I took it to Stag 4x4 in Auckland, and they said they knew someone who repaired them... I took the punt, and unfortunately didn't work for me (think there was too much damage) but they happened to have a second hand one they fitted for me with only about 3000km more on it than mine... Worked fine after that...

This was about 7 year's ago now, when I had the issues, but maybe can't hurt to give them a bell too and see what they think? I'd still pm rick-the-pick too, as he seems to be the BeCM guru!

Good luck!

Marty

As mentioned above Rick has a buddy in Australia that can handle this in his sleep. SHip him your logic board and be done with it. All this farting around with towing and a shop has already cost you more than having a board cloned.

Right took the advice and send the BECM to Turner Automotive who unlocked it and repaired the damage (no furhter details). Tested on their mule and sent back to me.
Passed back to my Indy who installed it and set the necessary settings. Engine ran and no issues apart from sunroof not working and rear windows trip an ABS fault?? (earth issue)

Today they try again and engine will not start, cranks but will not run. Dashbboard completely blank except fro SRS lamp lit and usual EAS christmas tree.

Take along my Faultmate and for some reason Turners have changed the VIN number (presumably to test it on their test mule) so Faulmate won't play as not licensed for that VIN number! (already researching a solution).

However more worried about current state of car:cranking, SRS on and nothing else apart from EAS christmas tree. Not sure what to try next and would welcome some more advice.

Thanks
J

So looks like the Indy has locked the new reapaired BECM :-? However the settings are now correct. However...

So at the moment...
Keyfob opens/closes central locking ok
Key in an on, dash blank apart from SRS light, HEVAC blank
Engine cranks but will not start
MSV communicates with BECM but no other ECU's (license issue being resolved)
When communicating with BECM MSV can communicate with all indicators on the dashboard ok and the centre panel also illumiates ok.

Indy doesn't know what to do next (thinks it is an earth problem) nor do I

Any suggestions?

Thanks

I had almost exactly the same snag a couple of years ago and it was due to a faulty lower board on the BECM. Replaced the entire BECM with a good used unit which sorted it. I was able to access the data on the board and wrote it to the new one using Rovacom SM035. I dont know what caused the fault in the first place as I purchased the car with the problem.

See my post about it.

Right. Sent it back to Turners and they now finally say that it is damaged. They are blaming it on the instrument cluster causing damage. I've looked at the circuit diagrams and the instrument cluster would seem to just be a collection of guages and indicators. Anybody had any experience of an instrument cluster taking out a BECM? Sounds highly improbable to me.

Indy has tried another BECM and instrument cluster and she fired right up.
