Thread: Engine disabled

PM sent.

Thanks Scouse. You are a gentleman. The EKA works fine.

For those that are interested, the RR.net page describes some confusion about how the EKA works for US and Aussie RRs, but I can confirm that this Aussie 2000 HSE used the following method:

- turn to lock FOUR times (this must tell the BeCM that an EKA is coming) - left
- then enter the EKA code as per normal (n x unlock right, n x lock left, n x unlock right, n x lock left)
- turn to unlock - right

You should get beeps to tell you it was successful and unlocking of all four doors instead of just the drivers door locking and unlocking during the procedure.

My RR tends to go into the "engine disabled" mode after being woken up all night by (suspected) rouge RF transmissions and then the fob wont work. I thought the fob didnt work because the battery was flat, but the battery wasnt flat, because it started fine after the EKA was successful.

Interesting little beasts that they are. My biggest problem is that all these cool interesting things about my RR that I am learning interest my wife and friends not in the slightest...

I hear you mate.... we all do.

You can put up with the niggly things, but when it just doesn't go, it becomes everyone's problem.

I went through this whole issue earlier in the year.

In the end I had to get a replacement BECM as the old one was shot. Unfortunately, the EKA code did not work for me so it has had a few rides to the workshop on a flat bed.

The next step up is to get your own diagnostic tool, such as a Faultmate MSV. Then you have the abiality to fix these electronic issues yourself. I don't have one yet, but I am very close to buying one.

Been there many a time. Thats why we hang out on the ínter-google-web, and more specifically here at AULRO regularly imitating some form of weird IT Nerds (sorry Paul and other IT gurus', but you know what I am getting at).

It's just nice to be understood (and related to) on the LR/RR/P38 subject.

I am back in the "ENGINE DISABLED - PRESS REMOTE" situation. Uggh.

I cant start the car. I can open it manually with the key, but only the drivers door unlocks. When I open the driver door, all the hazard lights flash and beeping goes off (but no horn alarm interestingly). If I try to start the engine I get the above message.

The problem is thus. Now I cant get the EKA procedure to work. It looks like it is taking no notice of the key turns at all. It doesnt squawk success or failure at the end of the procedure.

Also the "reconnect battery with ignition at position II" procedure is not working either.

The remote key fob is not turning off the alarm, or doing anything, I suspect because it is unsyncd. I cannot resync it because I cant start the car. The alternative sync methods do nothing.

I cant start the car because of the immobiliser. Paul38A has suggested that I give the BeCM the once over, so Im going out there now with the knucke dusters.

I will also check the key barrel on the drivers door and the flux capacitor in the delorian. Give me strength. I will report back in later.

Do you know how difficult it is to work on the BeCM connections when you cant get your passenger front door open? This thing is like a prison.

Having a look a RAVE for the 99-on RR there are two main ways your BECM gets at the engine:

1. The inertia switch when tripped causes the BECM to get a signal which I presume makes it send out error messages. Try pressing down the inertia switch. I have read they can be touchy.

Aside from cutting the fuel pump the inertia switch signals the BECM and therefore the BECM would disable the ignition coil relay as below. I would be seriously considering cutting all the wires off the inertia switch and just rejoining the two fat wires that carry the fuel pump current.

2. The main way the BECM disables the engine is to interrupt the earth path to the ignition coil relay. The main ECM will not allow other engine functions unless the ignition coil relay is on. So the ignition coil relay (RL23) is earthed via the BECM on relay terminal 85. There is a circuit labelled "with ship disable" which cuts out the BECM by providing a new earth path to the ECM at its main relay earthing path (pin 23 ECM). The wire from the earth side of the ignition coil relay is white. It goes to a connector C1357 on which the other side is a blue/red stripe wire (goes to pin 23 ECM). I assume this is where the shipping plug goes. Don't ask me where to find this connector. It should be somewhere sensible.

Personally I would fit a temporary earth wire to the 85 terminal of the relay. Jam a bared earthed wire in (with terminal 85) and see if this makes it go.

BTW the BECM end of the ignition coil relay earth wire is pin 9 according to RAVE.

Thanks bee utey, thats awesome info. I will read it 15 times before deciding what to do

Interestingly, it did start yesterday, after 7 hrs of fluffing around. But I have NO IDEA what I did. I just unlocked drivers door with key manually and all doors unlocked and she started. It ran fine for 20 minutes but the fob did NOT sync, so I still had no remote buttons working. After I accidentally dead locked it with the key (holding lock for 2 secs), I am back in the same situation - only drivers door unlocks and fob wont work. ENGINE DISABLED

Yesterday I pulled the door trim, checked all the door outboard station connectors, the door wiring loom connector and all the lock barrel connectors. EKA is still not working. Roadside assist came yesterday and gave up after 15 minutes saying I will need a Rover immobiliser specialist.

Stay tuned.
