So it will need to go to a land Rover garage to take the information off my one and put it in this one. Or wat about thees fellas that come out with the computers can they do it.
Anyone with decent Land Rover based diagnostics (Testbook, Faultmate Extreme, Autologic, some Sanp-on stuff and others) can read and store the original LCM information, the n write this back the replacement LCM.
I was battling with system failures and changed the LCM for a replacement just to test things out. As the replacement unit wasn't specific to my vehicle, I got some bulb failure messages, and also, my fog lights wouldn't work!
Replaced the original LCM and all was back to normal.
You are saying you currently getting a bulb failure message, this may be caused by a dodgy bulb, dodgy connection, dodgy wiring to the LCM, dodgy LCM connection, or a fault in the LCM itself. You have said the bulb is fine, the connection is fine, the connections to the LCM are fine, the wiring thereto checks out....and are now going to see if a replacement LCM will cure the issue....
What I am saying is, replacing the LCM may clear the bulb failure warning, but cause other issues, such as mine above i.e. no foglights. Or, it could still show the same bulb failure warning (plus others) but not because the LCM is duff, or that there is further issue - it could just be because the LCM is not coded correctly for the vehicle - so don't be surprised if you do get further issues.
The only way to properly tell if it is your current LCM at fault, is to properly code a replacement to your car and then see if the failure message disappears.....else you could be chasing your tail - 'is it the replacement LCM, is it the coding is wrong, is there indeed a wiring fault, bulb fault or connector fault?' we still wouldn't know as the only thing we could determine for definite is that the LCM is not programmed to your car - and this could cause more problems in fault finding than it can cure!
You may get lucky and the failure message disappears, you still have full functionality of all the lights and etc meaning the replacement LCM is doing the biz, but the vehicle records it stores will be wrong....so whilst on the outside you will never know the difference, if you plug it in and interrogate the LCM stored vehicle information it will be incorrect - mileage included.
