Thread: My D3 has got a bit of a cold

Okay the verdict after pluging the D3 into the computer and downloading the errors.

The Terrain Response ECU losts it's link with the Range Control ECU. The D3 uses a CAN BUS system (don't ask me how that works but is sounds like systems can be connected on the BUS and allowed to talk to one another).

The fault may have resulted from a couple of the plugs being sligthly loose. The plugs were reseated and errors cleared.

MLR (my dealer I bought the D3 from) told me that this was the first D3 to have shown these errors and they asked that any errors I get are reported and then investigated by them. LR want to know what real world faults are occurring to improve their build quality. You might say that we are guinea pigs but if LR do collect all warranty repairs and analyse the data to improve the D3 systems and build quality they will certainly improve their product. I'm all for this activity as long as it gets back to LR.

At the end of the day there is a certain amount of inconvenience but electronics can also be used to quickly identify out of spec components (sensors etc...) and the logs that the computers record help quickly identify problem areas as in my case.

My D3 is happy again until the next time.

Good to hear Chris,


It's nice to see a guy that is using his new landy like a REAL Landy..

After all that's what they are for

Good News Chris,
Its Great to see the D3 out in the Bush

Should have bought a new Defender and spent the other 30K on extras..
:roll:

the Defender has a drive by wire system, which if fails, does not allow you to accelerate...
It also has a self mapping ECU which, if fails, will not allow you to drive...
It also has traction control and ABS linked together which, if fails, could be a problem....

So I dont see why buying a new Defender would be any more "simple" in terms of electronic bits...[/b][/quote]

Lots of if's there landy_man ... "if my auntie had balls .. she would've been my uncle" :wink:
I'm yet to hear from a TD5 owner who experienced the above ...

Hi PCH, the CAN Bus stands for Controlled Area Network and is now an industry standard protocol or to simplify it. This is a system being employed in many new vehicles where the components literally talk to one another and the language they use is called CAN.

You will see much more of this type of electronic involvement in new vehicles because it has a whole host of advantages with probable the main one being that in the not to distant future there will only be 4 wires running around the vehicle, 2 for power and 2 for the CAN protocol.

This may sound a bit over the top but it will simplify every aspect of working on or adding to the vehicles electric's.

For example, you could buy a set of driving lights and only need to hook up 4 wires at the nearest point to where you are mounting the driving lights and again back at the dash you would fit your switch(es) and hook up to the 4 wire loop and thats it.

Both the lights and the switch would have a small microprocessor installed inside them.

The first time each device is powered up, the microprocessor in each device will tell the host computer that they are present and what they are to do.

This scenario will be common place with a large number of items that at present require lots of wiring and connecting to existing systems.

The CAN system will not only operate the additional devices but will let you know about how the devices are functioning. EG. If a driving light globe fails, you will be notified as soon as you turn on the ignition, whether you have the lights on or not.

Cheers.

Thanks Drivesafe for your explanation of the CAN BUS system. This explains to me why when I turn the ignition key to the start position the Message Centre says "System test in progress" and then chimes to tell me it has discovered an error like "Special off-road programs unavailable". The test has just discovered a system is not functional due to a loose connection or failed component.

One of the procedures I use in starting the D3 is to let the system do it's self test before actually starting the D3. I had read on another forum that a sudden voltage drop due to the current draw of the starter can give the system incorrect readings and then errors while it is doing the self test. The first time I didn't follow this method of starting I got a park brake error :roll: .

yeah, have not heard any of these happening on Td5 equipped vehicles...
only oil in loom and oil pump bolt problems... but when I owned my Td5 I was very cautious of getting the drive by wire potentiometer wet...
