Now really frustrated and the overengineered L322 02-06 immobiliser is really cheesing me off as it has left me stranded. Can anyone give some assistance with fault diagnosis.
Sequence of events as follows:
1. Insert key and transponder coil recognises key successfully
2. Immobiliser ECU successfully sending unlock signal to Steering ECU
3. Steering Lock successfully unlocks and then relocks steering 3 times (hence not the usual issue as steering lock working)
4. No signal sent the ignition barrel solenoid to release the key, hence cannot turn past 1st position
I know all of this because I have already swapped out the ignition barrel and verified that the transponder coil/key works. Also have checked the ignition solenoid and that is working. The steering unlocking mechanism is working because I can hear it working.
My thoughts were it could be:
1. Steering lock sensor not working - hence why steering unlock/locks 3 times
2. Steering ECU gone hence why no signal to unlock ignition and steering unlocked 3 times
3. Communication issue between immobiliser and Steering ECU
4. Wiring with any of the above
Is there anyone out there with some specialist knowledge?? Otherwise I am in trouble because it means: new car, low loader to a specialist and a huge bill and someone getting a very cheap Range Rover. Sad because the rest of the car is in great nick.
