Yep....looks like I was mis-informed or as your President would say 'mis-spoke'....

There is a rolling code between the EWS ECU and the ECM ECU......so yes, there appears to be a 'learn new code' issue....I doubt Rovacom Lite would be able to do it and you'd need something like the BBS Faultmate Extreme or something with some clout like the Land Rover T4 system to get the security system to relearn....Solus is not a LR specific system and as such may not have the right security protocols to force a re-learn of the rolling code.

The Rovacom-Lite is capable of doing everything the Faultmate will do, it is merely an older and now obsolete platform. It was with Colin's direction that I purchased the modules for use on the RCL as I had such urgent need and couldn't wait the week or two to return my RCl, have them transfer license codes to a new FaultMate and ship it back. In order to facilitate this repair and make it easier on both of us, his plan was for me to purchase these modules, install them on my admittedly nearly filled RCL, conduct the repairs and send the RCL in at my leisure.

With Land Rovers, there is little leisure!

Please do not take my earlier post as an insult as nothing of the sort was intended. This is a departure for me as I am frequently the one dispensing such info and assisting, but this truck is trying my patience and my skills. I have had great luck and positive experience working on the BMW powered L322s, but this one is taking the **** for sure!

As for the Solus, during my near five year tenure as a Snap-On franchisee, I told my customers that Snap-On is THE best for every vehicle, it is NOT the best for each individual vehicle. There is an amazing amount that CAN be done with it, but it is frustrating when one's needs exceed the capabilities of the tool-worse yet, Snap)n purchased the appropriate software from JLR, but refuses to be involved with anything security related..
 
Saint had a problem with the diagnostic port not working.
I didn’t read all of the above but it was the EWS/ Bosch engine ECU link my L322 lost a few times and I had to program again, as recently as last week.
Have you tried the BBS forum, you might get lucky.
If you are not cranking then it is probably not immobiliser as even if immobiliser the petrol still cranks, well it does with the BMW electronics and engine.
I would check you have a good 12 volt + supply to your fuses that are fed by the ignition as I had a TD6 with a bad ignition switch that had multiple system errors including immobiliser and also systems that wouldn’t connect at all via OBD.

I would agree, were it not for the fact that the Snap-On tool magically communicates and none of the others do.

I am afraid my next course of action will have to be disassembling the centre console to access the ignition switch proper.

But how can the snap-on tool communicate???

BTW-an RSW solutions scan tool could not communicate either
 
Before taking anything apart you can check the voltage on fuses in the glove box using a pointed probe, you don’t even need to remove the fuse, there was a recent thread on here telling you what fuses to test or look in Rave electrical manual

As a result of a thread on the BBS forum, I independently powered the RCL-no dice. I'll find the thread and check the voltages

Thank you
 
This is one of the threads and this was cranking but I couldn’t connect to a few systems. The TD6 doesn’t crank when immobilised, but this vehicle started doing a half crank, then no crank and then lost power to the dashboard lights.
As this was a diesel the fuses might be different, the electrical diagram is available from Rave download or google.

Thank you.

This truck doesn't crank-likely due to the immobilizer issue.

Yesterday I was disappointed to learn that if my DEC SuperScan would connect, it has a function for resynchronizing the EWS with the EMS ECU :-(

I was in the right place at the right time and was given a spiral bound factory publication of the circuit diagrams for NAS trucks. I have quite the reference library for Land Rovers up to 2005.
 
Is yours petrol ?
Does it have touchscreen sat nav?
An immobilised M62 L322 engine will still crank if you have Bosch ME7.2 and EWS3 immobiliser your engine will still crank if immobilised
The TD6 doesn’t crank when immobilised
If you have multiple systems that won’t connect via OBD2 but some that will I would say you have a power issue
 
According to the ETM/FSM, the immobilizer inhibits cranking.

"On petrol models, the immobilization ECU energizes the starter solenoid via the starter motor relay. Page 86-5-22
 
@PTSchram nothing to do with the question in hand but just been looking at your website. I knew it would be more expensive running an LR over the pond , but I'm shocked at how much more expensive :eek: Almost 7x the cost for the smallest of parts! Makes me thankful for small mercies!

And I try to be a low cost supplier. The parts on the site are the more obscure-at least here

Question Andy....

In my recent vid I posted for RichardSEL I should one of my spare keys without any electrical gubbins in it at all, I showed it is possible to turn the ignition switch on, but because the EWS wasn't getting a signal, it wouldn't crank the engine over.....

So how come as you say above if the immobiliser isn't 'satisfied' with a working key, it will crank but not start....whereas in my video...it didn't even crank?
 
But you aren’t getting to the cranking position are you ?
The TD6 I had that was immobilised would turn to the cranking position but nothing happened if I did the steering lock ECU disconnect, otherwise it would not turn at all. That was because the key wasn’t paired.
My petrol when immobilised by losing the EWS / Engine ECU link would crank the engine but not fire but that was with a transponder paired key.
You can’t turn the key to the cranking position without a transponder can you ?
You should be able to unlock the steering without inserting the key in the barrel by touching the key fob onto the ignition providing it has a transponder.
So your steering unlocks if you put a key in the ignition that doesn’t have a transponder ?
The TD6 I had would not allow any turn when the key wasn’t paired.

Yep.... at time code 59 seconds, I turn it to the crank position - but nothing happens to prove that nothing will happen...and then when it goes back to pos 2 I can't do a crank again and have to take the key out and back in again, turn to 10deg, back to 0 then I can go to pos 2 and into crank for another go.....
