Thread: 2007+ Immobiliser strikes yet again.

What model year is your defender? What do your remote control fobs look like?

Mine is a MY2013 Defender. LR Malaysia told me that, rather than just replace my security unit (10AS) with one the same, they have to install a completely security system from the then current 2015 model year. (IIFR that incl. instrument control unit and engine ECU as they are matched etc)

Even my remote control fob had to be changed to match the newer security system.

The original remote fob looked like this.remote old.jpg
The new remote fob I have now looks like this.remote - new.jpg

Fortunately LR agreed to all this under warranty! It wasn't broken, worked fine, they just couldn't tell me the EKA for the original system.

I could understand why the security unit (10AS) would need to be replaced for one with a known EKA. I asked why they were replacing the entire systems and the answer: We cannot source the older (10AS) units for my model year any more.

So be alert friends if ever your (older) security system dies....you might have to replace more than you think.

So I have the BAS tune on my ecu. It will replace that? I can’t do that

yes I have the first fob. And mine is 2013

Better double check with them what they are doing. In my case it involved the ECU. Might be different for you.
(In my case - replacing the ECU may have more to do with issues around not having the vehicle VIN encoded properly. e.g. I bought a nanocom evo hoping to use it to turn off the immobiliser whenever I go bush. The nanocom never worked as it could never see the vehicle VIN)

When I bought into the BAS tune it was back when BAS shipped an unlocked ECU free of charge with the tune tool etc, so I had the original ECU as a spare. I put the original back in before returning the vehicle to LR. After I got it back, just put the tuned ECU back in, and repeated the linking process to link up to the new security module - using the BAS tool.

Yeah cool. I the same unlocked ecu. So I can put the old one in

I tended to do that whenever I left my Defender with LR in any case.... it only takes 10min to swap in/out once you have done it a couple of times.

If they do change your 10AS you just have to repeat one portion of the BAS installation process to get BAS ECU talking to the new 10AS:
- refit and connect up the tuned ECU
- enter the service/test menu
- press "renew 10AS"

BTW - I just checked the email exchanges at the time (Sept 2016) and confirm that LR Malaysia changed:
- ECU (maybe not needed for your vehicle?)
- 10AS
- Instrument computer
- (not mentioned previously, forgot it).... a new cable loom.

Would have been expensive if I had to pay for it.

After chatting with Pete Bell last night he thinks my immobiliser may be ok. He thinks it could be something shorting out seeing as I was working on my headunit while this was happening. My interior light has gone funny and stays on. As the control for that and the immobiliser is in the one place he is saying if I get the light right the immobilser should follow

Sounds reasonable. Any fault codes when you connect the BAS tool and go to the appropriate menu?

Defender 90 2013 2.2l. Immobilizer appears to have a fault cannot start, lock or unlock. The EKA code did not disarm the immobilizer. Engine will crank briefly sometimes but mostly will not crank at all. Has just been sent on a float to Melb City Land Rover Port Melbourne. They claim to never have heard of the fault.
I changed the fob batteries. Disconnected the car battery to reset the electronics still no joy. Immobilizer light on tacho is flashing and will flash corresponding to a fob button push. interior light will turn off with a fob button push. A fob button push will sometimes make the immobilizer light go out then nothing happens at all. interior lights will not work with the door the door. The central locking will not operate off the driver door sill button. I think the instrument cluster did not light up as well. This issue could be expensive

any guidance would be deeply appreciated
