Most Autowatch alarms lack information about how to find alarm fault codes their user manuals. This makes trouble shooting very difficult for anyone other then an installer with access to the installation manuals, so it’s almost impossible to find out why your alarm has gone off unless you can get it to an approved dealer.

Nearly all Autowatch alarms will store the alarms trigger history, however it only remains in the system for 10 cycles of the ignition being turned on and off.

For a quick diagnosis of why your alarm has gone off and to prevent it from being a nuisance the following information is vital:

How to access diagnostic trigger report back.

To enter trigger report mode, the owner simply has to turn the ignition on and off to count the LED flashes. This is the same method as you would use to enter your over-ride PIN number, the details of which can be found in your user manual.

Easy as 1, 2, 3!

Well almost. Wait for the immobiliser LED to start flashing, then enter the code 1, 2, 3. Then the LED should flash rapidly for a second or so. (If not let it flash more then 11 times and start again!)

If you have an alarm without an immobiliser (279RL, 458RL, 555CLAM, or 695 CAN) then you’ll need to force it into flash mode. The details on how to do this will be in your user manual which I’ve put direct links to at the bottom of this post.

Next enter the code 1,1. and the LED will flash a number (or multiple numbers) that corresponds to what circuit has caused the alarm to go off.

Note: Do not enter any number other then 1,1, at this stage as doing so could damage either your alarm, your cars electrics, or both and cause it to work in an undesirable way!

Here’s a video to make is clear, below that I’ve put the fault codes for each model of Autowatch alarms on sale in NZ.

    Hi I have a 446 RLi – with the led and microwave sensor in one unit. The led stopped flashing some time ago and now I cant even reset the alarm unit by checking the led. WHAT must I do?

    I suggest you get your local Autowatch dealer to fix it for you.

    Thanks for your quick reply!
    I hope the system is still fine; I had issues with my cars wiring, and my battery. Hopefully the 440RLi didn’t get damadged with with the repair and trouble shooting of these issues.

    Double check your battery voltage, and alarm will not work if it is not powered up!

    Hi Clive,

    You are welcome to book the van in with me so I can do a current draw test.
    If installed correctly there should be minimal drain on the battery. Have you contacted your installer about this?
