When the transmission gear selector is in the PARK position and the ignition is in the OFF position '0' a shift interlock solenoid is de-energised, locking the transmission gear selector in the PARK position.
The transmission gear selector can only be moved from the PARK position when the ignition is on and the brake pedal is depressed. The brake pedal switch signals the BCU, which in turn signals the Intelligent Driver Module (IDM) to energise the shift interlock relay in the passenger compartment fusebox. This energises the shift interlock solenoid allowing the transmission gear selector to be moved from the PARK position.
Ignition key interlock
The key interlock solenoid prevents removal of the key when the transmission gear selector is not in the Park position.
Transfer box interlock
The transfer box interlock prevents the transfer box being shifted from 'H' or 'L' with the key removed from the ignition switch. A transfer gearbox interlock solenoid is controlled by the IDM which energises the solenoid and prevents transfer box lever operation.
Ignition and Shift Interlock Supply
Circuit supply
A feed from the battery positive terminal is connected by an R wire to the engine compartment fusebox where it passes through fusible links 3 and 8 and fuse 13.
A feed from fusible link 3 is connected from the engine compartment fusebox on an NR wire to the passenger compartment fusebox. The feed passes to fuses 20 and 21 in the passenger compartment fusebox.
A feed from fuse 13 is connected from the engine compartment fusebox on a PN wire to the passenger compartment fusebox. The feed is connected to the IDM and the coils of the interlock and transfer box relays.
A feed from fusible link 8 is connected on an NW wire to the passenger compartment fusebox and from the fusebox to the ignition switch on an N wire.
Ignition switch supply
With the ignition switch in position II, the feed from fusible link 8 flows through the ignition switch to the passenger compartment fuse box on a Y wire.
The feed continues through fuse 25 in the passenger compartment fusebox and is connected on a GO wire to the brake pedal switch.
The transmission gear selector can only be moved from the PARK position when the ignition is on and the brake pedal is depressed. The brake pedal switch signals the BCU, which in turn signals the Intelligent Driver Module (IDM) to energise the shift interlock relay in the passenger compartment fusebox. This energises the shift interlock solenoid allowing the transmission gear selector to be moved from the PARK position.

There is a trick to get them out of park if you are stuck, just pull up the cover for the 'prnd12' shifter and push in a little solenoid to get it out of park.
You can feel around until you feel the little button and then you can push it into neutral to start.

Then I suggest you need to get an autoelectrician to check the relay and switch etc.

Yes will do and thankyou . Do you think it could be a big job £££ ?

Probably worth shopping around a bit, price, and ideally someone experienced with LRs.
The one I use charges 30quid a half hour, comes here bringing all wires, teminals etc. He covers a lot of ground in a half hour, wouldn't have thought that would take long for an auto sparks.

Answer Gems, he is local to you, and will help!
And don't worry, he is a proper gent, not an uncouth inbred like the rest of us!
