2001 td5 fault codes

well I plugged my d2 td5 in today and got the following codes.

10. can bus off (intermittent)

2. inconsistencies with driver demand (intermittent) 'throttle pedal I know'

10. injector 3 short circuit (intermittent)

anyone have any ideas?

EDIT: its auto sls has been disabled and so has a.c.e

What did you plug in?

A Delphi diagnostic laptop, bit annoyed that it didn't give me any p codes

you can get P codes only from OBDII compliant engines which the Td5 is not, or from transmission.... if that reader is only OBDII based those codes might be fake anyway, if they are real the CAN bus fault is about a momentary interruption of the CAN(controler area network) datalink which is the connection between the engine ECU and the transmission ECU, this connection is in the ECU red plug so check that for oil which might affect the contact... and it would explain the injector fault code too .... which means you must replace the injector loom ASAP

Oh right that explains the p codes, I knew its not obd II, the code reader is a professional garage type which has a menu where you select the vehicle you wish to connect to, I pulled the red ecu plug last night and it does have traces of oil in,
I will get a new loom then, sods law I only changed the rocker gasket 2 weeks ago could have changed it at the same time lol

before fitting any parts, clear the fault codes and test drive the car and then retest for faults as they maybe historic codes

They arnt historic codes, the can bus error has been there about the last 5 times now after being reset, but this time it was plugged in I got the driver demand and injector faults as well.
ill change the loom for how much it costs.

Hi all instead of starting a new thread I thought id reuse this one as its still ongoing,

I replaced my injector loom months ago but im still getting the 10. can bus off (intermittent) code returning after its been cleared,

and im also having problems with the auto box if say I reverse out of a parking space then select drive I get the m & s lights flashing on the dash, it didn't happen too often at one point but now its every time I use car in the same scenario.

ive scanned for faults and have the following code ; 0E position switch monitoring. plausibility. intermittent
ive checked the ecu plugs and its clean and no signs of oil

is it possible I have some sort of earth fault

did you check the plug at the transmission ECU too to be well connected or not have some corrosion or something cos these faults are from there... what about your charging system and battery? any weakness there could cause such troubles

second hand EAT ECUs are not so expensive, i'd try another one to rule it out if i was you

alternator charges fine, and the battery is about 6 months old noticed the difference straight away when that was fitted as it turns over loads faster than the old battery did and still does.

where is the eat ecu located?

could the fault be my xyz switch

if the fault is the XYZ switch you should have got specific fault codes for it, even that "position switch" fault which is related to XYZ switch is about "monitoring" which means the initial diagnostic check... also CAN fault has nothing to do with it... provided you used a proper LR dedicated scanner this time not and OBDII reader again

plug in a nanocom or hawkeye or any other LR specific tool and see what fault codes you get then before you spend money on bits...

the EAT ECU is under the LH front seat

ok understood, my scanner reads all makes of car you just have to choose what car you are scanning the codes from I select landrover then discovery 2 then 2001 diesel, then td5 then 10p automatic so it cant be pulling codes from thin air and must be correct.

Edit: could it be than when I start her up im too quick too engage drive and confuse the ecu, more or less milliseconds after let go of the key when started I engage drive

it's not pulling codes from nowhere but these multivehicle readers are not always the most accurate unless they are proffesional which starts from 1000 quid... i checked by my curiosity some fault codes on my car with my multivehicle VDM UCANDAS(which is not the cheapest tool but not proffesional) set to my D2's modell then with Hawkeye which has the original T4 main dealer's protocol and they were not entirely the same...though quite close to reality

i attach you the LR specific codes then see if what you've got is in the list or not

"and im also having problems with the auto box if say I reverse out of a parking space then select drive I get the m & s lights flashing on the dash, it didn't happen too often at one point but now its every time I use car in the same scenario."

I had the exact same problem on mine. I cured it by changing the switch on the side of the gearbox, and it is spot on now. It was dangerous before when pulling out of a street parking spot it would go into limp mode and would only try to pull away in a high gear with no revs. VERY EMBARASSING.

but did you get CAN and "monitoring" fault codes too? cos if not the fact that the XYZ switch was faulty on your's it's irrelevant...if you watch those attachments you'll see that there are 14 reasons for flashing M + S + limp mode and the "gear position switch incorrect outputs" which means faulty XYZ switch is just one of them

I Have to be perfectly honest, I did not see the readout on the tester. The guy I use does nothing else but Landrover, and he is very good at his job. If there were other fault codes, I am sure he would have explained to me what they were at the time, but I cannot remember being told of any.

right ill type the codes out as shown on my laptop screen

Diesel (10pa - TD5 MT/AT)
DTC Description

10 .can bus off
.intermittent

Gearbox (Gearbox - Bosch GS 8.87 _ AT)
DTC Description

0E - position switch monitoring
- plausibility
- intermittent
fault is present no
fault requesting MIL no


is this clearer for you the diagnostic machine is Delphi which uses a delphi multiplexer interface and the latest current Delphi software

so i can't figure out what those fault codes mean... IMO you should have got fault codes as on that list to be certain about what's wrong

what kind of diagnostic tool you've got?

no I cant see any of the codes shown in the brackets....... the gearbox fault code is 0E (zero e) its a Delphi diagnostics laptop

if its one of them Delphi interface Chinese copies which are for sale everywhere I personally wouldn't risk even plugging it in any of my vehicles
