05 LR3 V8 4.4 Won't Start
Hi,
My LR3 Won't start after being working on it.

I create a build thread but is not getting much attention thats we I decided to post here.
https://www.disco3.co.uk/forum/impossible-...04803.html

I'll try to resume everything briefly ..

Picked up the car, was running, started with no problems.

had parking brake fault, looks like module is dead, nothing happens when press the button.
also High and Low gear button didn't work, always stuck on High.

After few days having the car it start raining, notice carpets wet. found lots rust under drivers side.

decided to strip interior to fix floor board, disconnect grounds on driver footwell and B pillar to be able to lift wire loom and fix rust.

second day was raining, connect all grounds, start the car no problem and pull inside garage.
work on the rust and start car again no problem pull car out.

had the battery of for about a week while fixed rust and start looking at the wiring on both sides, found a couple splices corroded and fixed them.

Connect battery try to start, nothing.

bunch a codes:

- Lost communication with immobilizer
- Lost communication parking control module
- lost communication instrument cluster

what I did:

- Replaced parking brake switch

- checked all grounds that I disconnect and reconnect on the B pillars

-clean transfer case module (some corrosion there)

-check battery ground cable (removed and clean connections)

- hard reset

Connected battery again, key on the ignition, cluster showed “key on the ignition” message and the car started!!

No more "Lost communication with immobilizer system"

still other faults when scanning Parking brake module and transfer case module, but no more faults when scanning transmission module.

After few minutes tried to strart and nothing!! again Lost communication Immobilizer, emergency lights blinking and doors cycling.

after a bit started again!!!!

Thought about replace battery since I didn't new how old It was and voltage was low, after few days I came with new battery and it doesn't start again!!!

Same immobilizer fault, suspension dropped, HDC Fault transmission Fault on cluster.


Anyone have wiring diagrams?

 

UPDATE!!
Been looking around other topics, and found instructions to jump start starter relay. If I do that the car cranks but don’t start.

So I think I can rule out any problem related to the starter.

Must be related to the Immobilizer fault.

How can I test Immobilizer key chip? I only have one key and when I got it the key wouldn’t work with doors.

Can’t scan itHi in

 

Hopefully we can help you, but I'd post in the LR3 section of the forum.

 

Thank you, I’m doing that right now!!

 

I have a 2006 Land Rover LR3 that was trying to start but won't. I've noticed that alot of fuses and relays are missing and I need to see if that could be why?

 

You need to start your own thread injuredbeauty...

 

And post it in the LR3 forum.
