QuestionQUESTION: Hello, I have a 2000 Range Rover 4.6 HSE. The remote will not lock or unlock the doors, but it appears to have plenty of battery life left. Using the key manually, the doors all lock and unlock, and it works fine in the ignition. Also, there are no messages stating any problems with the remote, or other. I don't know what to make of it?
Secondly, My sunroof does not open, close, tilt or slide, and I don't hear a motor running. It's just dead?
Any advice on these issues would be appreciated. Thank you!
ANSWER: The keyfob may have lost synch, put the key in the door and turn to lock, hit the lock button and hold for a second. then do the same for unlock.
If the sunroof has never worked it may have been turned off in the BECM by the previous owner, some roof-racks are too close to allow opening, so it is turned off to prevent damage.

QUESTION: Thank you for your very prompt response. I should have mentioned, regarding my remote key fob, that I had the dealer try to synch the remote, but they did not have any luck either. I did not have them investigate any further, thinking that I would do some reseach on my own first.
In addition, I am not able to access any information from the trip odometer by using the buttons on my turn signal lever, but I do get some other messages there, like the common "low washer fluid" message.
Lastly, and again, the sunroof not functioning.
Are these issues likely to be a BECM problem?
Thanks again, you are appreciated!

ANSWER: I don't think it's a BECM issue, that typically rears it's head in a worse way.
Did the sunroof never work, or did it stop one day?

QUESTION: Thank you for getting back to me, you're great.
I recently purchased the vehicle from a LR dealer, as is, and the sunroof did not work at that time, or since. I took the switch apart, thinking that it might look like it needed replaced, but it looked fine; and I probably wouldn't know if it looked bad anyway, unless it appeared burned out or something.
Is the dealer able to use their diagnostic tools to determine exactly which part of the sunroof system is bad, without having to pay them to tear the whole thing apart; for example, the motor, the relay, or a short in the wiring?
Thanks so much for your help and your time!
AnswerAny diagnostic tool will tell the mechanic the problem that it sees, not always the exact problem. There's not alot of diagnostics available for the sunroof (typically it works or doesn't). The diagnostic tool should be able to send an open/closed command to narrow down whether it's a controll or operation problem
