Sport Degraded mode range rover sport 2.7 tdv6

Hello english friend

Because of my heating problem https://www.landyzone.co.uk/land-rover/heating-diffusion-problem.351639/

I dismounted a part of my dashboard, including the center console with the armrest and the air suspension system and shift lever. I also unplugged my speedometer.

I reassembled everything and I put my vehicle on the road,I tried the suspensions and everything went well, for 10 minutes all went well then the degraded mode arrived ...

I have checked all the connections in my center console and I still have the same problem.

With icarsoft here are the default codes that I find without being able to delete them

U0126 steering angle sensor module
U0155 communication instrument panel module absent
U0102 Communication with the control module of the transfer box - absent
U0122 dynamic vehicle control module - communication not present
U0100 engine management module / transmission control module - communication not present
U0300 internal control module - incompatible software
U0101 Communication with Transmission Control Module - absent
B00D2 warning light of the restraint system 1

I would add that I have an anti-theft alarm that cuts the vehicle after 25 km but when I turn on I can disable it so I do not think it's that.

thank you in advance for your help

I managed to roll about ten minutes and then the defect came back

Sounds like a connector is not fully together

Nico2121 · Oct 22, 2019

OK thank

At startup there is a yellow light, and an F on the dashboard and after 5 minutes appears an E all the lights come red, and no way to start.

All fuses are good. Is the fact that the battery is unplugged a day is causing this problem? My key that has reset ... Tomorrow I will look if I have everything reconnected.

rest steering angle first
check battery voltage and charge voltage these have common problem with alternator and will light up like a Christmas tree

Nico2121 · Oct 22, 2019

For you it might be the battery, but what's odd is that it starts very well.

I’d guess something’s not connected up fully/wrong connections, but it starts okay?

Does the lock- to- lock need doing for steering?

Hi

did u unplug ur passenger side dashboard airbag or mess around with the steering wheel airbag

U codes u can normally ignore

as mentioned double check everything is plugged in properly , have a look at that airbag connection , if it is unplugged DO NOT plug it back in without disconnecting ur battery first , wait 25-30 mins then plug it back in

Hi thanks for your reply, no lock to lock has been useful for management, my vehicle behaves normally for 5-10 minutes, only a yellow light and a F described. Then everything comes on and an E and if I turn off the vehicle I can not turn it on again.

Hello and thank you for your answer, no I did not touch any airbag, I did not even hit the wheel. This afternoon I will watch the connection behind the speedometer, after I did not touch anything else (except for all the connectors on the gear lever but I have already checked).

Good morning all.

Today I disconnected everything and reconnected my connections taking care to blow them, and I think the problem is gone. I did 80 kms in 1h30 and the fault did not come back, so it's probably due to a bad connection to a place. Tomorrow I leave for 1400 kms in 3 days, I hope that the problem will not return.

Good evening to you

As I said, a connector not fully home.

Bonne route.

Nico2121 · Oct 23, 2019

Yes I guess it was maybe the connector behind the speedometer that was badly put but what's odd is that it's a record like that so you can not put it badly because there is a pin to close from above.

But the main thing is that it's okay.

Merci

Do your blend motors work okay now?

Nico2121 · Oct 23, 2019

The blend motor works but I still have no heating left .. I'll rest a little after this fright

and then I go on a weekend, I'll see next week ...
