I bought a 1997 4.6 HSE yesterday in beautiful condition for an absolute bargain. (That makes four Rangies cluttering my driveway). But with some issues.
It seems to me like a BeCM problem but I have my doubts. Nothing shows up on the instrument binnacle when the key is turned on except the SRS light comes on for around 3 seconds. Everything else in the car works OK. Lights, elec windows, central locking, radio, HEVAC, etc. etc. Engine not running yet as I dont have the EKA code and the remotes will not synchronise but it does crank. Dealer is closed for the weekend. When the key is inserted in the ignition the small red led on the remote flashes continuously.

I have swapped the top board in the BeCM for one off my other car and the problems dont change. Same with the fuse box. Checked as many earth points as I can find and re plugged every multi pin plug I have come across. The wiring in general appears sound.

Unfortunately I dont have the BeCM module for my Rovacom.

Any ideas?

I am nervous of swapping things due to the odometer mileage reading or lack of. I have no idea what the mileage is on the new car and would hate for it to end up with too many miles on the clock after it syncing with whatever new components I test with. I had a good look at the insides of the instrument binnacle and it all seems ok. No sign of any damage but you never know, Time to buy the Rovacom BeCM module I think.

John. I think there is more wiring in the cigarette lighter circuit on a Range Rover than there is on my entire GT40 so cant use anything from there.

Master plan. I will swap both the BeCM and instrument binnacle from other car. No need to worry then about mileage. I wont be able to start the car but it will help with diagnosing the snag.

Did the BeCM / binnacle swap and everything worked. So now I know where the problem lies. I pulled the boards out of the BeCM and lo and behold someone has had a go at repairing the bottom one. A tiny bit of non standard soldering that I only noticed using my jewellers eye glass.

Off to the breakers tomorrow to try and find a new BeCM, lock set, key fobs and whatever else.

Dam. I was hoping for something simple.

Viper. Do you know of any broken Rangies up in Joburg? Maybe Phil has got something.

Car is mobile. Swapped BECM and ECM. Running like a dream which makes me laugh as the "experts" told the previous owner that the car will never drive again.
A bit of TLC and it will be a fine vehicle.

Thanks for all the suggestions. Now to get a new BECM and ECM and keys so I can get my other car back on the road. I just hope that the faulty BECM is not to badly fried to retrieve the data for the re-program.

I have no idea of the mileage on my car. If I re-fit the original instrument binnacle to the current BECM how long will it take for the values in the binnacle to change to match the BECM or vice versa. I only need it connected for a couple of seconds to read the mileage. The serviceable BECM I have fitted is from a fairly high mileage truck and I would hate to end up with its numbers on the new beast which I suspect has a much lower figure.
