Disco 1 300 Tdi 1996 - Immobiliser Problem. Help!!

Afternoon All - Discovery 1 300 tdi 1996 Manual.

Bit of a problem. Was Out laning with a few lads and decided to go through a very deep ford - Luckily truck made it thorugh and cabin was full of water (seat high) as i came out the immobiliser light came on. Drove it back home with no issues but immobiliser light remained on.

This morning tried turning it over and nothing happens. Central locking has also Stopped working, key fob is dead!

So all help appreciated once again ladies and gents

Ecu now faulty due to ingress of water maybe ok if dried out but doubtful, time for a replacement then.

Oops. Try get hold of your eka code. On the off chance it may get it mobile again

Central locking is working again on the key. and alarm goes off as i open the door on central locking. hope i make sense

Where is the ecu located on the 300tdi (1996 2 button fob) and is it easy to remove?

It's on the passenger side mounted with a number of relays, remove the black panel under the glovebox

If your setting alarm off with key the eka code will start it up. Will rest everytime you lock vehicle though. But for a temp fix

Thanks pal.
Have taken it out to see if i can dry it out.
If not will have to replace it.

tried drying it out but no difference -
Guys will the new ecu require programming to the truck or is it straight forward plug in?

Do you know what sort of imobiliser you have got, if you get the fobs with the Alarm then that's one less thing to have to programme.

Yes my fob has two buttons so it has the alarm.
Anyone used a spider bypass before or where i can get a amr 6429 unit as replacement?

If you aren't fussed about retaining the alarm and remote locking then, you should be able to bypass the stater circuit and diesel pump cuts relatively easily

I dont really give a Sh*t about the alarm and remote locking tbh, just want the bugger started!!

Have a search on here there are a few threads on here on how to do it. In short assuming you have a single wire solenoid then you need to supply 12v to that with the ignition on, and then give the starter solenoid 12v from the final stage of the ignition switch.
