Thread: How to clear the "Service Required" message on a D4

Actually Land Rover seems well aware of the various local market realities. As such, with the NAS models, they seem to dumb them down for us.

In my specific case, they even put a hole in the roof with a glass slider above the front seats so I could crawl out when I got the "round knob" setting wrong, and tipped it on the side - the "up side" door gets a bit heavy and all when it has to swing vertically. Cunning, those Brits.

And yes, I wondered if the Faultmate could cancel the key chime, but my understanding is no. I also kind of figured that, as if the dealer cannot, (or maybe, will not), but I think that the NAS spec software might just forbid the turning off of the key in chime, so one would have to change the LR3 into say a UK D3, software wise.

Also in going thru the Ford pickup forums, it seems the guys are for the most part cutting wires or fooling with the ignition key cylinder, and that there is no software only fix.

I do however see that in the Fuses section of the 3's Hand Book, there is a 5 amp fuse, 40P, in behind the lower glove box called "Key In Sense". I gather however from a disco3 forum post that pulling it somehow effects the parking brake - maybe just the indicator light but .... There is also a second 5 amp fuse F41P, called "Electric Park Brake" so maybe I should pull F40P instead of just writing about it and see what happens.

Well I pulled F40P fuse in the fuse panel behind the lower glove box and yes, the chime did not ring with the key in the ignition but ....

Two warnings appeared, one the round red Park problem indicator light in the Speedometer area lit up and remained lit; also a message displayed in the rectangular message display area that said Parking Brake Fault. Hence the fuse went back in and for the time being, I remain defeated.

I have attached a couple of pdf's of the parking brake wiring that I interpret to mean the wire from the key in ignition signal is CAN BUS related, no real surprise.
