2005 V8 HSE Multiple Faults and getting to know the gap tool

[timdo1]

Hello All.

I have recently bought a 2005 v8 HSE with several problems. I mentioned a couple on the Disco 3 assembly thread (below) but I didnt want to Hijack so I thought I would start my own.

Disco 3 assembly

So this beast has major water issues inside the car thanks to the A pillar trims and the sun roof drains. This seems to have caused every fault known to man, a dashboard lit up like Christmas, a transfer case stuck in low range, no suspension or special programs. Ive fixed that for the most part. I still have a small amount of water coming in the passenger side trim which I will solve with a different seal around the clip, its not enough to wet the carpet and I have temporarily taped so nothing comes in. The carpet is all dried out, I have pulled apart electrical connectors and earth posts on both driver and passenger sides, cleaned off some rust on a earth post, cleaned out all the electrical connectors. Opened and check for corrosion the Central Junction box. I have also had the transfer case ecu out and removed corrosion in the plug and checked inside the ecu and couldnt see any water issues in there. I also checked the ecu behind the transfer case one but found no water issues in the plug. I was net going to look at the wiring on the front passenger wheel arch, that will be over the next couple of days.

Then the gap tool arrived yesterday so I linked that today, cleared faults and cleared them again. Most of the faults were gone except something odd around the steering angle sensor, the transfer case and a few others.

So I found the steering angle calibration portion on the tool and did that procedure, a whole heap of faults disappear.

Here is the list of faults that are left.

Body Control

B1B02-28 (2F) Low frequency coil - General signal failure - signal bias level is out of range/zero adjustment failure
( on 07-10-2021 14:28:48 at 303900 km )

B1C57-14 (2F) Passive start ignition relay coil circuit - General electrical failure - circuit short to ground or open
( on 07-10-2021 14:28:48 at 303900 km )

Engine Petrol

P0695-00 (2A) Fan 3 control - circuit low

Transfer Case

P0902-00 (2F) Clutch actuator - circuit low
( on 07-10-2021 14:28:53 at 303902 km )

P0915-00 (2F) Gearshift position - circuit range/performance
( on 07-10-2021 14:28:53 at 303902 km )

Ventilation

B1B78-84 (2F) System pressure - Bus signal/message failure - signal is below allowable range
( on 07-10-2021 14:28:52 at 303902 km )

So my next questions resolve around the Transfer Case. I figure if i can get that going I will be able to drive it normally and special programs will work???? I will then deal with the other issues. I have noticed that there are calibration procedures with the gap tool for the transfer case. Is this a danger area if I just do it? I'm running a little blind at the minute so if someone could fill me in with what these do and if that relates to my errors that would be great.

My second question for today relates to the car electrical system in general. When i turn the engine off and remove the key, 5 seconds later the hazard indicators come on, the heater fan, the navigation screen and the dashboard all turn on. I can also operate the windows. Does anyone have a clue where to start chasing down this fault? I thought it would go when I solved the water issues, but it hasn't.

Thanks in advance.

Hey mate,

I threw a transfer case in my d4 and had to calibrate it, i can't remember what the code was first, but it didn't cause me any issues

Trouble shoot that relay error and hopefully the power stays off.

How does the key feel in the barrel, still tight out lose and floppy.

I'll dig my laptop out later and have a gander at the errors

[josh.huber]

Those body control errors are reported on other forums as a ghost code, the ventilation code is likely low gas, or a dead sensor, good luck with the transfer case

Can the scan tools run a seance to sort it out?

Hi, My problems (Disco 3 assembly) were caused by a canbus wiring fault. Even if continuity checks are ok but there is damaged insulation on a wire in the canbus system, this can generate fault codes.
Another defect that I found related to the multi-pin connectors at the rear LH wheel arch and next to the battery. If the pull-in studs on the male side of the connector are missing, the plug may not seat squarely thus creating a poor connection.

I was really curious about the fault because of the description, a few sites said it's always active in their cars.

[timdo1]

Thanks for all the suggestions so far.

Today I pulled the centre console. I noticed that the little light on the shift is always on D no matter what position the lever is in. Also dont have the the individual gear selection ( dont know the land rover term for it). After a bit of reading I discover that these modules go faulty. Trying to find a second hand one now. Waiting on some replies. I assume that will get rid of the gearshift position fault problem.


Next I will focus on the Clutch actuator cct low. I suspect they are talking about the actuator for high low on the transfer case. I've read that these go funny and the wiring can do same. I'll do some more research tonight and try to get underneath it tomorrow to look further.

Just to make things interesting I'm leaking water from underneath. At first I thought split hose but I looked today and its coming behind the harmonic balancer. I suspect water pump up higher and dripping down. Hope so anyway, that looks simple. These things are a bit tiresome to bleed arent they.

Lastly I cant get the air suspension to work at all. I will have a look at the rear connectors and canbus as per Airmech953 suggestion. Thanks by the way. I can use the gap tool to reset the heights, then as soon as I try to adjust it freaks out and drops to the bump stops. It did work yesterday using gap to raise it, but its stopped again. I'm thinking a dodgy connector somewhere so lets see.

josh.huber You think there is a relay issue which is why the car turns back on. That one I havent started trying to sort out. Its strange and I dont know where to start. I will note that the main fuse box under bonnet had water dropping directly on it, thanks to a loose seal. I cant remove relays etc close to the windscreen because they feel stuck. I havent had the guts yet to really hack into that because the damn thing is hard wired and a nightmare to replace. One area where I wish they stayed with the D2 setup. I'll start to play again with that this weekend. I'm thinking I might try some anti rust stuff to loosen anything thats rusted or corroded in there and then lots of contact cleaner. Not sure what else to do at the minute. Dont want to damage that part of the car due to replacing difficulties.

Thanks for all the suggestions everyone. Keep em coming, I'm new to these beasts and the learning curve is steep. So far they are simpler to work on the the D2 TD5 or V8.

The D illuminated will be corrosion on the shifter PCB caused by water or a spilt drink, pull the plug off the PCB and check for corrosion.
I had to replace my shifter and the short loom that connects to it, i suspect you may have other moisture related issues so check the passenger side sill channel where the wiring runs for water.

I couldnt get to the sill the other day. I might pull the seat this weekend and see if I can get to it.

Thanks for the thought
