Speed 6 Immobiliser

[BlueSix]

Following little use over winter my cerbera is refusing to start. The rear screen LED flashes about 4 times in 6 seconds which according to the manual indicates bonnet open which isn't surprising as I had to charge from flat. When I use the key fob to unlock and immobilise it lets me in ok but on pressing the ignition button wont turn the starter and the LEDs continue flashing rather than the usual 10 sec opportunity to start the car. The dash lights up ok.

Any ideas??? before I go to the unpleasant expense of having it recovered 50 milis to my bearest TVR garage.

Thanks !

Hi, have you tried the overide fob?
When the ignition is on and you press the keyfob are the lights not going out?
You may have corrupted the alarm CPU froma voltage spike!

I'm assuming you charged the battery while it was still in the car, if so disconnect the Battery and leave for 30 seconds before reconecting.

PS If you want to know why, ask

[RUSSELLM]

Metal key ?

[BlueSix]

When i press the fob the LEDs go solid on then immediately revert to flashing. How can I reset?

The battery was charged in car. I disconnected over night. I've got to ask.... why?

Thanks

When you press the black ignition button, you mentioned that the dash lights come on. Does the buzzer come on aswell, and can you hear the fuel pump prime ?

[BlueSix]

Thanks for your help, I've just been out and tried again. Yes the buzzer sounds and the fuel pumps prime. I tried the metal key in both positions. Dash lights up when turned clockwise, doesn't if anti clockwise.

Thanks

Could be the old knackered immobiliser problem, in which case, keep your finger on the black button for five minutes

However, Jitzz had similar symptoms recently, and his turned out to be a duff 40a fuse in the passenger footwell.

Explanation as to why you have to disconnect the battery...

If the battery runs down to a certain level, the immobiliser detects a fault,kicks in, and 'listens' for something to happen. If you charge the car up slowly while the battery is connected, the voltage in the battery just creeps up very slowly and the immobiliser doesn't 'hear' it, so it remains immobilized. A reset, ie disconnect the battery, wakes the immobiliser up. It's recommended that you disconnect the positive lead from the battery, but becaue this is a PITA, try the negative lead first, and if it doesn't work, then do the positive.

[BlueSix]

You're kidding about finger on the black button for five minutes?????? if not I do have some children willing to earn pocket money. What is PITA? I have tried disconnecting only the positive terminal, I'll try disconnecting both and jump leads tomorrow.

Thanks

I've got into the spirit of this now ratherthan copping out and sending to the garage. I was wrong yesterday the fuel pump does not prime. I have taken the foot weel trim apart, i can't see an obvious fuse, just a couple of electronics boces one is the wiper unit the other I'm not sure but reads MBE systems?

Any advice would be gratefully received.

Thanks

Hi, the alarm control boxes are not in the footwell, my alarm fuse is by the battery in a waterproof fuse holder.
Have tried the overide key, so don't use the remote just press the car ignition and push the override key in the slot for about three seconds this should un-immobilise the car.
If the light still blinks you have a problem with the alarm control box, you try disconnecting that for five minutes.
Good luck.

Thats assuming the Speed six has the same alarm as a 4.2!

Tried the override key. didn't work

There is no fuse by the battery either, where is alarm control box? I'll try that next.

Thanks

[BlueSix]

Does the ignition buzzer come on ?

Presuming it's connected & comes on normally.

[BlueSix]

No ignition buzzer bit the alarm makes the necessary noises when locked and unlocked. Nothing when i press the black button though.

Hi, the alarm control box is behind the helmet holder (again assuming the speed six is the same as a 4.2!)
Try un-plugging the large white molex connector for five minutes.
good luck..
