Title: Removing immobiliser ECU
Post by: I_want_an_Omega on 20 December 2010, 21:13:16

Hi,

Am struggling to get it off the steering column. Can see a release tab in the corner nearest the driver, but is there another one somewhere?

Thanks - Rob

I have removed them without taking out the barrel but you risk damaging it if you don't...

They are a lot easier to remove with the barrel out :y

OK 2 seperate problems there Dave...

1) Fob - the fob needs re-syncing with the car. Ignition on to red lights and press the lock button. The doors should lock then unlock and it has re-synced.

2) Immobiliser - Is the orange engine light flashing while you're turning it over? If it is then check the the small chip is still inside the key itself and not loose.

I bet when you changed the fob battery teh immobiliser chip fell out, check the key to see if its there and if its not, look where you changed the battery for it (small black chip)

Surely being an M plate would mean it had the older seperate fob?

On some of them the larger single button fob also had the blade key incorporated, hence why the seperate fob still has the place for the chip to sit, and the blade section filled in.  :)
