I bought my STR used and chassis VIN is different with the VIN showing in the JLR. The chassis VIN is 67543 and the number in the JLR is 55737.
When i am making the test in the instrument pack , The last two digits are 43, according with the chassis VIN.
Now when i tried (sorry for my english)to configurate the ECM (like existing module)in the JLR, the car does not start.
The problem is that i cannot communicate with the ECM in the JLR how i can see the ECM there , anydodys help?
I can communicate with all the other modules with the JLR , so is not this wrong.
In the past, sometimes was communication, but the most times not.
Any help please. SOLVED thanks to Jagmans post.
