Hi everybody,

I leave in France and i like land rover (excuse me for my english)

I bought Range Rover L322 3.0 TD6 MY06 and i have a problem with them.

When i turn on the key before starting, the light came on (ABS, brake and and a yellow triangle).
I have a message that says "HDC is not avaible"

Affter starting the motor the light are always on.

When i drive a few meter i have a new message that says "suspension is to low. I can't choose air suspension position but the suspension have a good level.

In order to solve my problem i bought :

-JLR SDD 131 with mangoose cable and SPA / VDF file.
-New battery and i test alternator
-new steering angle sensor and i test with SSD (it's ok)
-I change ABS ECU with a used ABS ECU buy on ebay
-I check the ABS fuse
- I test ABS with SDD and i have a problem: the sensor is ok but precharged pump don't run. When i test the pump directly with 12Vand without ABS ECU , the pump is ok.

I test steering angle sensor and it's ok:

After many test with SDD, it's maybe the yaw rate sensor because yaw rate sensor have given bad data in the past.
I change this with a used buy on ebay and i have always the same problem.
With SDD i don't found if we must calibrate yaw rate sensor...

SDD in diagnose mode:

Today I haven't active DTC but the light are always on.

-DTC "C1A70-1C / C1A71-1C " it's me during my test, i unplug a cable.
-DTC "U0428-86" came because i remove the battery in order to change ABS ECU, yaw sensor... after i calibrate always.


I f you have an idea you can save me:(

Thank you so much;)

Where abouts in france are you?
This is a little more complicated than my P38 but... D
you have pressure in the air tank?
Can you read the pressure?
Do all your height sensors work?
;)

I leave at Nantes, near the sea.
I have pressure in the air tank.
when i test with SDD i can up and down the car with the soft.
All height sensors works fine and i can see height sensors data with SDD

We need an l322 "know it all" here to help talk computers??
It sounds like something isn't talking to something else?
In the boot area, is there any humidity in there?
Are all the connections to any ECUs dry and without corrosion inside them?
We live 50mins above Bordeaux. ;)

I steer well clear of the L322, the electronics were designed by a madman.
OP,
Recherchez de l'eau ou de la condensation sur la garniture à l'arrière gauche du coffre.
s'il vous plaît excuser mon pauvre français

No worries just because I cannot comprehend grammar doesn't mean I cannot read and write, took me a long time to be able to write clearly in English, still make lots of mistakes, what I write does not always express what I mean.
I speak enough French to do what I need to do and understand if people speak slowly. For writing letters, translation programs are a boon, the result does need editing but forms a good starting point and I can read French pretty well..:D
 
i speak the lingo in a fashion but cant write or read in french, expressive writing is an art and shouting is much faster!!:p
ive got the kids as my little google translaters:cool:

I had same problem with my 2005 L322 after a lot of good suggestions on this forums page
pick up my thread about a water leak and read it all may make some sense but ill bet its to do
with battery disconnection this might not help but it worked for me

Merci pour la réponse en français ;)

Merci

Need to use T4 to diagnose and code the ABS on a 2006MY L322 not SDD

Systems are split across both diagnostic systems

thank you td4van,

Are you sure that i can't code the ABS ECu with IDS SDD V131?

I have also SDD V138, but i test only with SDD131.
