L322 DTC U0426

Good morning all,

So I explain my problem to you. Range rover l322 V8 SC vehicle.

My problem started with a lambda probe which apparently had a mass problem. After a lot of research with changing the probe, checking the beam, the solution to the problem was found: it is at the ECM that this happens. Between pin 34 (the mass of the lambda probe in question) of the ECM and the mass of the vehicle that things are not right. The circuit is open, whereas there should be continuity. The problem does not come from the soldering of the pin on the ECM electronic card I checked. So here is for me the simplest replacement of the ECM because as it does not receive the good info from the lambda it enriches to the maximum, the consumption is huge, seeing the engine and above all I can not repair the electronics like that.
So buying a new second-hand ECM, reprogramming with SDD that I have, it injects the VIN of my car well into. Only I have the immobilizer blocking the thing. Error code U042600, meaning immobilizer code error. On the manual it is marked with a reprogrammer as the new ECM and the instrument cluster. Done, the operation for the instrumentation cluster is determined, for the ECM at a moment I ask for a blank module and the installation stops. In short, the error code still present.

So can someone tell me to re-program the immobilizer with SDD so that the immobilizer code is injected into the ECM?

Mass is French for earth for anyone looking at the problem. I don't do the L322.

Yes pardon the mass, it is the earth in electricity in France. Even if you don't do l322, do you know with the JLR SDD software how we can program the learning of the immobilizer code for the ECM?

Sorry, I know nothing about the L322, @Saint.V8 is the expert, now I have tagged him he may show up.
Where in France are you?

I live in Poitiers in the department of Vienne. Perhaps you have already heard of the futuroscope an amusement park?

I thought that was @Datatek 's estate.

Not far from me then, I live in Latillé. I have not only heard of Futuroscope, I have been there 2 or 3 times.

Morning Keith, I checked my cable and all seems fine, haven't contacted @martyuk yet, my WiFi is intermittent at the moment, guess there are so many people on it in the area. I hate leaving things without an outcome.Stay safe.

Morning Alan when you say WiFi are you talking about the internet connection via the land line telephone?
If you are and it's a WiFi problem it may be the modem in your house rather than the internet system.
If you are using a portable device on the mobile phone network, it may indeed be overloaded.
Keep well.

Yes it's a mobile network, Thanks.

I think they should get 4G working properly and with sufficient capacity before they move on to 5G.
Having a 3G signal is a novelty for us, they have just put up a new mast a couple of kilometres away.

Sorry, I have never used the SDD system, only All Comms and Faultmate Extreme for the BMW based EWS system. If yours is S/C Jag AJV8, I am in the dark as how to help you.....sorry.

It is all the muppets Zooming. Why you need to see a picture of the person you are talking to I don't know, unless it is Dirty Debbie with the D-cups from Derby.

Thank you for your answer. For those who might be interested in programming a second-hand ecm module, you can do so by programming a new module under sdd, thanks to that it will register your wine in the cmos of the calculator. Of course launch jlr sdd with the original ecm (otherwise problem), let it collect the data and once ok, put the other ecm and start programming. Now you have to inject the immobilizer codes into the ecm ... And that's where I block. A priori under IDS it is necessary to delete the car keys to reprogram them and force the modules to synchronize again ... Only in Sdd I don't find how to do that ...
