Just Brought A 2007 Auris 1.6, Alarm Problem

[tony2311]

We seems to have a problem with the Alarm.

Some times when you unlock and open the door, the alarm goes off.
Press unlock again then the alarm stops for a second or so and go off again.
The only way to stop it is to close and lock doors.

This has happen a few times already today.

any idea on how to go about finding the fault?

Remove the existing alarm system and chuck it off, then fit a brand new one, regardless is Toyota genuine or aftermarket...

Usually, an alarm system lifetime is 3...5 years.

Can i disable/remove the alarm but keep the factory remote locking?

[tavy]

It must be a CAN-BUS alarm system; first you have to identify the module (where is situated inside the car) and unplug it, then central locking will work normally.

can you tell me where and what i should look for?

[tavy]

It can be anywhere behind the dash, because it needs a +12 V, a ground and two wires from CAN-BUS. You'd better ask an electrician from Toyota.
