Estrarre il circuito stampato con la batteria - Exctact the printed board with the battery18 viewsRimossa la parte superiore del contenitore, estrarre il circuito stampato sollevandolo leggermente dalla parte della batteria.
Removed the top of the box, pull out the printed circuit board slightly lifting from the battery side.

Brake Switch Visible thru Opening4933 viewsThe blue and white bit is the switch; the sort of gold appearing box,(it is really black), you will not see in your 3 as it is a Smooth Talker brand amplifier for my Blackberry phone antenna. This install is detailed in the SmoothTalker phone antenna section of my gallery.

One way to remove and install the switch is to lower the "horizontal" panel above the brake pedal as shown where the flashlight head is located. To actually remove the switch, you slide your hand thru the gap and rotate the switch clockwise 1/4 turn while watching thru the rectangular opening. Installation of the new switch is the reverse of above - 1/4 turn counterclockwise.

Before you remove the switch, note its orientation - horizontal with electrical wires to the left. That is the way it should look after replacement as well.

The second time I replaced the switch, I did it all thru the rectangular opening and did not remove the horizontal panel - that is experience helping out.

The knee kick you have to remove regardless. It is sort of hinged at the bottom so you just pull at the top and sort of rotate the knee panel and then pull upwards for two plastic "fingers" to clear the slots they reside in.

PS: note that my disco has manualy inflatable air sping in addition of the standar terrain response.

Key_in_Ignition_p_222.pdf
Key in Ignition Electrical Wiring Diagram1043 viewsThis shows the key in ignition wiring, (LGW, 1.5D), running from the key lock cylinder to the Central Junction Box, (CJB), thru 5 amp fuse F40P, located in the fuse box behind the lower glove box door.

You can remove the 5 amp fuse and the good news is that the ignition chime will not sound any longer; the bad news is that a bunch of other circuits that rely on knowing if the key is in or out no longer work.

Also note the Transponder Coil D219 reference.
Land_Rover_LR3_Trailer_Wiring_Harness_YWJ500220_C.jpg
Harness that connects inside left rear compartment.435 viewsThis is the harness section that connects behind the left rear interior access panel and exits thru the large grommeted hole to below/behind the left rear tail light.

Note the two rubber grommets on the harness as there is both an interior metal skin and an exterior metal skin behind the left tail light assembly.

The two light grey connectors plug into two existing connectors near the top of the rear left interior access panel. The two darker connectors plug into the second piece of harness.

There is no little separate fuse box either with the NAS spec harness. The fuse box is included with the UK 13 pin dual plug units. If there was a fuse box, it would be on this portion of the harness.

Horn Wiring Circuit LR3575 viewsThe is the wiring diagram for the dual horn circuit.
The Horn Relay, (R133), is not a big black thing hidden somewhere but instead what is called a FET, (and it is hidden)!

This is a Field Effect Transistor that is built into the circuit board that is mounted to the back of the fuse box that is located behind the lower glove box door on the passenger side of the 3. The related 15 amp fuse, 12P, is mounted in this fuse box and is often called F12P, where F is for fuse, and P is for Passenger compartment.

This is to help differentiate from another fuse and relay box, (the usual kind), that is located beside the starting battery in the Engine compartment. FxxE is often used in the naming of those fuses.

Stop Light Lamp Circuit pdf2460 viewsThis pdf shows the brake light circuit for the NAS LR3.

Note that power for the brake light bulbs can come either thru the brake light switch power feed /contacts plus also from the Hill Decent Control, (HDC), system relay located within the Central Junction Box, (CJB) - yes two separate sources of power for the brake light bulbs. This would tend to explain how a brake light circuit concern shows up as a hill decent fault message; also why lesser vehicles without hill decent braking mechanisms, (HDC), never display this sort problem when a brake light bulb or switch acts up. You never have a problem related to a system that does not exist.

Additional evidence of the relationship of the HDC and the tail light circuit is demonstrated by when the HDC actually acts to slow the 3 down, the brake lights automatically illuminate even if the slowing action was merely retarding the engine speed or shifting to a lower gear, (in other words, no foot on the brake pedal).

There is also a tie in to the Cruise Control and hence a failing brake light switch can affect cruise operation or just create false Cruise Control messages. To further complicate the issue, while there are no messages generated, operation of the radiator electro viscous fan can also be negatively affected by the fouled set of secondary contacts within the brake light switch. This is all because the NC contacts within the brake switch send misleading messages to the ECU.

While the ground wire design is similar to other vehicles, note the grounds for the brake light filament and the reverse light filament are common on each side. That means that if one has a non functioning brake light on one side, the reverse light may not also work or that some problem with the reverse lights could back feed into the brake lights. This situation while unusual, can result when grounds are corroded probably due to swimming in rivers and creeks or just routine driving in a marine environment.

Relay_Air_Compressor_70_amp__YWB500220.jpg
Air Compressor 70 amp replacement relay1384 viewsThere is a software update, 09 April 2010, LTB00270, for the compressor which reduces the shut down pressure to about 205 psig (14 bar). The update is usually done when changing to a new compressor and also includes replacing the R7 relay in the engine compartment fuse box, 07 DEC 2010 LTB00331.

The newer grey case coloured relay, part # YWB500220, shows to be rated at 70 amps, (the relay, not the compressor), however the previous black case coloured relay also indicates 70 amps.

Both the new and replaced relay show on their wiring diagrams to have a parallel voltage spike resistor, (probably 560 ohms), across the coil terminals, #1 and #2. This means one does not just replace the relay with any four prong 70 amp ISO sized relay that one happens upon.

One presumes the grey relay is either upgraded or just being installed for good measure. The relay is common on Ford Fiesta for the seat heater relay, Ford part number 5M5T 14B 192 EA; also Volvo, part number 30765034. The Tyco part number moulded on the grey body is V23136-J4-X62.
