Two hydraulically dampened engine mounts are fitted between the engine support brackets and engine sub-frame to
reduce the level of transmitted engine vibration and noise.
The damping characteristics of the mounts are regulated by controlling the rate of hydraulic fluid transfer between two
internal chambers.
The system consists of two hydraulic mounts, with variable damping regulated by a vacuum, a control actuator,
electric and vacuum lines. The vacuum, controlled by the electrical control actuator, is supplied via a distributor in the
vacuum line between the vacuum pump and brake booster. The system is controlled by the EDC System.



Wouldn't want that engine interferring with Bach on the stereo:D:D:D

It really is true that modern devices are tremendously dependent on electronics. Luckily, they are mostly much more reliable than mechanical systems (to do the same thing).

You left out the fibre optic connections. I believe the D3 and Rangie use some fibre links as do other vehicles now days.

Our BMW MINI had a data bus around the car and "nodes" on the network to operate various things. Ironically, that was one of the less troublesome aspects of the car :D

Yes the 1990 RRC upwards uses fibre optics to illuminate the lights for the indicator & wiper storks on the steering column

Luckily, it's not a big item

:p

The key to all of this is the reliability they are building in to these systems.

If you want to scare yourself silly though check out this link:

Microsoft - Windows Automotive (http://msdn.microsoft.com/en-us/library/aa286536.aspx) :eek:

Reminds me of the joke about the three engineers and the car not starting...
Electrical Engineer: I think we should check the wiring from the battery to the starter...
Mechanical Engineer: Maybe the we should remove the engine covers and look inside...
Microsoft Engineer: Why don't we close all the windows turn it off and then open all the windows and see if it starts.

Is it just me or do electronic systems not like dust, water and vibration....................makes sense to put em in landrovers then :p:p:p

Its just you:p

The reality is they should be sealed from dust and moisture and made to take the vibrations. e.g. The ballast on an HID spottie can last for years on a Landy, but lucky to get 6 months out of it on a CAT D11 because of the vibrations. But then 6 months of near continuous operation isn't bad either.

That said some electronics are not built to meet the conditions they are used in.

I see DirtyDawg has been doing some studying & learning how things work in his newish "posh toy";)

It is mind boggling to realise how many ECU's do their job.
It is better than the P38, where everything was controlled by the BECM (or the big box under the drivers seat).:p
At least this way u just replaced a smaller module instead of the whole heart...& is damn cheaper...

Hope ya beast is treating you well.:D

Cheers:)

Mr Dawg.
Now you know what they are called and have the ability to find out where they are located. Why don't you blow your mind and find out HOW they work ?:o
I'll give you some clues:
Which components have memory capacity ?
How is this memory capacity used to "imprint" the components the module controls to the vehicle (and they do this by a form of VIN number )?
Which components store data about operating parameters ?
How much of this "hidden" data can be retrieved and by whom ?
and on and on.........:mad:
The biggest clue..............none of the above applies to most of the light bulbs !:cool:
enjoy!:p

BTW my padded cell is the third on the right hand side:angel:

I dunno! Storks are pretty big! :o

Chev. Corvettes had fibre optic instrument lighting way back, 1960's. They say it was the first commercial use of fibre optics.

X2 Why I drive RRCs, Series and 4bd1 120" in Land Rovers. :p The Last rovers I will ever have here. Dust, Water and Rocks:eek:

[dmdigital]

I think you'll find there's also fibre optics in the some of the "wiring" loom.


The fibre optic system installed uses Media Oriented Systems Transport (MOST), which is a multimedia network,
optimized for automotive applications. Its design allows it to provide a low-overhead and low-cost interface for the
simplest of devices, such as microphones and speakers. More intelligent devices can automatically determine the
features and functions provided by all other devices on the network and establish sophisticated control mechanisms
without distracting the driver.

Under normal installation conditions the system is robust and failures should not occur. However, since the optical fibres
convey data using infra-red light, it is vital the passage of light down the fibre is unobstructed. Obstruction of infra-red light
can be caused by:
􏰀 Contamination of the fibre ends.
􏰀 Damage to the fibre ends.
􏰀 Bending, kinking or damaging the cable.

L322 Range rovers have a fording depth of 700mm, Defender is listed as 500mm....seems water isn't that much of a problem hey. Aircon has a pollution filter, pollen filter on top of the standard filter...what dust problem and as for vibration....thats funny...once you ride in a L322 you will laugh too....:p
