Immobiliser Fuse Position?

May 1, 2010

Following on from my immobiliser problem I have now discovered the Battery is going flat very quickly.

Which fuse controls the alarm/immobiliser? l would like to test it by removing the particular fuse to see if it stops the drain. What 'code' do Toyota use for it in the fusebox?

However, by taking out the fuse will it also prevent the engine from starting?

Its a bit "suck it and see" - you'll have to fiddle.

This is all I have on the system;

Thanks for the PDF's - they're very helpful.

It seems like the Battery has had it as it won't hold a charge for more than a few minutes. Both the terminals appear quite' wet'.

Seems a bit strange though - could be a coincidence that the day we fit a new ECU the Battery goes. However, we're going to check for a drain first and take it from there.

lt doesn't seem possible to 'disable' the alarm/immobiliser.

Here's the alarm manual , the ECU is fitted to the left hand end of the dashboard and is accessed through the glovebox ( easy to remove ) there is a 10mm bolt to undo the ECU plus some butyl sticky stuff holding it in , once removed carefully drill out the two pop rivetts which hold the cover over the plug then remove the plug . This will disable the Alarm but check you indicators still work with the ECU disconnected if you intend driving the car .
