here is what I do when I am diagnosing or tracing huge issues. I print the section of interest from the ETM section of the rave, then tape the pages together as a flow chart of blue print.
then I spread them on a table and highlight the concern as I trace, because of the way the rave is formatted which of course seems to be scanned copy of the pages of the service manual, there really isn't a clean way of looking at it.

 

I was hoping to find an old fashioned drawing of the complete system, but it's looking like a printing marathon is more likely, which is a total pain as there are proper drawings for the earlier Range Rovers and also the later ones... It would appear that LR were experimenting with flow chart type drawings in the early 90's and have now reverted back to more traditional ways...

 

A 95 is far more complicated than old single page schematics from dinosaurs of the 80's. In addition those single page schematics left alot of information in question. Be happy the PROPER diagrams are available for 95s as they save alot of people alot of headaches.

 

It's all well and good if you've a part of the dash not working, like a gauge, but not so helpful when you've got over 30 connections to trace... And those less than useful schematics, as you say, are now the the norm for the L322.... all be it a few more pages than the classic, I think about 500, but what they show is the item and all the connections to it... unlike the confusing stuff that I've got for the 95 RRC that shows the wire and what it goes to... For something that could be covered with one page there are over 60, many of them duplicated, but under different headings... to say that I put it all down before I lost the will to live is an understatement ... I'm beginning to think that a multi meter or a battery might be the way to go having identified the speedo a other large items...

 

G`day , when you say dash pod is that the entire dash , heater controls , switches etc does yours have ABS and do you wish to use the traction Control , i would imagine you won`t use SRS , will you use the smaller steering wheel ,would depend what you want as to how much of the wiring would be needed , do you know the instrument have a CPU ?
Or do you mean the part the has the instruments ?

I agree about the searching needed to find where things go and how they are connected or relate to each other .

We had an LSE Soft Dash which was replaced by the L322 the LSE had a fault with the aftermarket fuel pump and because it also ran LPG it had a few wires cook because here the petrol is wired to pump all the time on either fuel , the injectors are turned off on LPG.

There were wires melted under the bonnet , under/in the dash , along one side and all of the pump wire from the pump up to and along the roof at the rear quarter .

It didn`t take all that long to repair but it took hours and hours to trace wires and work out what they did and it wasn`t straight forward because the melted wires didn`t need to be part of the problem they only needed in the same loom or fastened to what had melted .

Luckily we also have a SE Soft Dash which was helpful when things didn`t make sense .

If there is an over all wiring diagram for a Soft dash i can`t find one even the Power and Earth distribution don`t have an over all they are piece by piece .

The L322 Flow type thing is much easier to follow and it does give an over all of the Power and Earth distribution so you can see what is common to what and how things relate and then can go to the specifics of what is needed .

The Soft dash one is nothing but hard , time consuming work at first i thought it was me being used to the old type and i`ve always agreed with " a poor workman blames his tools " but in this case i think it is the tool .

 

Well I'm not changing the dashboard to a soft dash, just the instrument binacle, ie, the speedo tacho and other gauges / warning lights.. And it's from a Discovery TDi300 1994... same as a RRC 1993> but about a tenth of the price as it was for a Discovery and not a Range Rover!! I have yet to have a measure up to see if I'm going to have to make major adjustments to the binacle to get it to fit... but whatever happens it will be going in... even if I have to use a Discovery binacle pod!!

Yes I could have gone for a 1990>93 dash pod from a hard dash RRC and it would have just dropped in place, but they are hard to come by and carry a high price tag, then I'd also have to buy a loom to get the right plugs for the conversion.. the cheapest dash that I could find was £70 without the loom.... I got the Discovery dash and loom for £37 delivered to my door with a free light cluster and clock... that will be going up for resale to recover some of my costs.... So it might need some adjustment to fit.. so what? still cost way less than the RRC item... and if you've got a softdash it is the same unit!!

 

G`day ,

for what you intend the RAVE thing should be ok , specially since you were able to get the loom , for the plugs i presume .

I had a look at the ETM and E1 , E2 and E3 have all you need and the trouble shooting for each section gives which wire etc that is used .

Don`t much like your chances of an easy fit , they don`t look very similar and the later one has bits on the ends the other doesn`t . Where 1 comes out by undoing from underneath the other comes out from the front in the Range Rovers .

The RR and Disco are similar but not same , the speedo , tach , temp and fuel and SRS are the same but the RR has more lights than the Disco , like TC and EAS for what your doing it wouldn`t matter .

If i wanted to fit a complete unit to our Soft Dash a Discovery one is not a straight swap and i know this because when we got this Soft dash the SRS lights had been removed and i learnt there are 2 SRS lights/globes not 1 as it appears .

Soft Dash parts are not plentiful here and i knew there were similarities that the Disco had but on inspection there are slight differences between petrol and diesel and neither have EAS or TC that the RR has .

Your will , i think also have a mechanical/cable speedo and the Soft Dash is not but i guess you are aware of that .

I look forward to seeing a picture of it fitted but if you don`t have theDisco cover i think you`ll need it and then i guess you could make good use of the extra switches around the cover . The RR doesn`t have the same piece it`s top cover is one piece and the length of the dash , people say the disco dash looks like the RR dash and they do share some bits but when looked at are not that similar .

 

I'm all too aware that it's an electronic speedo... that's why I'm doing the job in the first place, my new transfer box is from a late defender and most of the rear output is not interchangeable with a cable drive speedo!! So it's not because I'm trying to make the RRC in to something it isn't (thinking of some P38 to L322 jobs I've seen) it's because I'd like a speedo that works and I really don't want to do a major gearbox strip / hybrid rebuild job... if it's possible, which knowing my luck would be a very costly exercise!!

And I'm aware that the dash is mounted in a totally different way, hopefully I can lash up something that works out of the 2!

 

G`day ,

is there something different about the way a Defender and Range Rover electronic drive works ?

 

Not as far as I know, they are both 6 pluses to the revolution... only the RRC / Disco had a remote unit on a short flexi cable drive and the defender is bolted direct to the box... although the later Discos adopted this system!
