Hello all, this is a great site and while I have lurked before this is my first post. Anyway, trying to help out a family friend with a problem, seems to be a quite a few knowledgeable people judging by the intelligent and accurate responses, so here goes.

Here are the specifics. 2000 4.6 HSE. Everything seemed OK and then one morning -no start. I went to check it out and the battery showed only 4.9 V and looked a bit old. I know these vehicles need a good strong battery so I replaced the battery. All of the electrical functions seem to operate fine, and I checked all the fuses and they seemed OK. So I went ahead and checked to see if the starter was capable of cranking the motor(jumped the terminals). Starter worked fine. With the key in the ignition switch in the "run" position, the vehicle will not start when the starter is jumped- but I suppose that might be the way this vehicle is set up? Anyway, I had a hunch that this vehicle may be experienciing some sort of anti-theft "lock-out" so I took a peek around. Under the dash on the lower left it appeared that this vehicle had some sort of generic alarm installed(had a generic valet toggle and interrupt button) so I removed the under dash covering and found a mass of wiring that did not appear factory. There was a harness that looked like it might have been plugged into a box, but the box was gone. There was another smaller black box that had two connectors - one going back to this mystery harness, and the other snaked up to the ignition cylinder and made a loop around it. Looked like some sort of exciter ring? This struck me as a bit odd, but Ihave always had problems with non factory alarms and remote starters crapping out so I then figured it might be best to disconnect what remained of this system and try to restore the original wiring integrity. I carefully removed the aftermarket harness making sure that all of what looked like the original wiring remained intact. The only wiring still left attached to the mystery harness runs through the door harness on the drivers side and I haven't pulled the panel off to see where it is connected to. Still no luck at this point.


The only thing I hear when the ignition is turned to the start position is a faint click which appears to come from the BECM. Nothing else happens.


Question now is, where do I go from here? Could that other small black box that I removed be a necessary component(it did NOT look factory-but the connector with the loop of wire around the key switch has me scratching my head.. I did find while searching the archives some folks that have experienced roblems with the computer going into a theft mode and requiring a lock procedure to reset the computer. Do I try an EKA 1515 procedure with the key? Is it at a point where the BECM will need to be repaired/replaced? Is there anything else I can do before telling these folks to take it to the dealer?


Sorry for the rambling on-just want to give as much info as possible. Any help that can be offered would be greatly appreciated.

Sart at the beginning.What method is used to gain access to the vehicle.ie is the orginal Landrover key fob still used and is the remote buttons on the fob used to Tx a signal to unlock/lock the vehicle.You need to ascertain whether the orginal access system or an aftermarket one is being used, to at least get a starting point. :thumb:

Thanks for the prompt replies. I am going to head over there this morning and take a few photos. I hope I don't have any trouble posting them. I don't think they use the fob to get in the vehicle(knowing these folks, they probably don't lock it), but I will ask them.

What is the proper EKA reset procedure? I have seen some say say that you just cycle the key in the door cylinder (unlockX1, lockX5, unlockX1, lockX5 then just unlock the door and it's reset?

Thanks again,

Depends where in the world you are - post a location for more specific help.

I am in Eastern USA- New Jersey.

Went back out there today and worked a little more on it. Tried the 1-5-1-5 procedure, to no avail. But maybe I was doing it wrong?? Like I stated previously, there is an audible "clicking" from the BECM when the key is turned to the start position. I am assuming that the signal wire to the solenoid isn't getting power when the key is turned on. Frustrating. but I guess I am at the point of tracing out the wiring to see where the problem lies. Would be great to see a schematic of the start circuit.


Another thing I had considered is the PRNDL switch on the trans. How often are these things failing- if at all? I would imagine that a faulty PRNDL could cause this, but I tried moving the gearshift around with the key in the start position and got no response. Maybe the BECM just took a crap??

Thanks, I guess I will stay at it. Thanks for all the help, if anyone can add anything-feel free. I am losing the rest of my already thin hairline on this beast. :?

Do you have a copy of RAVE? There is an electrical troubleshooting section with diagrams, pin outs etc

Do the indicators flash as you enter the EKA?

Well, here is the update on the 4.6....

I took it as far as I could from a diagnostic standpoint and reached a dead end. I decided to haul it over to the local L-R dealer to see what they would say. The guy is telling me the BECM will need to be replaced-at the very least and there could be other issues he couldn't say. I kinda knew this was coming. The unfortunate thing is that these folks have dumped a ton of money already into this thing in the last 6-9 mos. and they are at the end of their rope. I am trying to figure out a way around the issue, if one exists. I know there are cheaper replacements out there, but will anyone(outside the L=R dealer) be able to program it without any specialized proprietary software?

Any guidance on where to go from here would be greatly appreciated. I do own a repair/custom shop-but my work consists of mainly 60/70's American Musclecars. I do have some regular customers that own later model vehicles that I regularly service-but I see few L-R's in here so my knowledge of what's out there is limited-but if I can find a way to repair it and have the info-I can do it.

I know why people like these vehicles, but the ownership experience can be wickedly painful. /:(

Thanks in advance for any help that can be offered.
