Toyota Hi Lux Alarm Fault


Ranger 1
 Share

Recommended Posts

I have a 2008 Hi Lux and the alarm keeps activating for no reason. It can be parked for 5 minutes or an hour and just activates. Audible and indicators flash. I can reset it and after a short time it will go again. The only way to prevent this from happening is to leave the keys in the ignition. Obviously not a good solution, no alarm armed and keys in......

I have seen others have the same trouble but I haven't seen any answers / solutions to this problem.

Ideas please ? ( sensible ones only )

Hi Ranger. Did you get any resolution? Successful results? 

Others have checked the alarm system wiring (soldered joints and wire degradation), switches (bonnet and doors), turned down the alarms sensitivity, replaced vehicle batteries, but still have the alarm activating at random times.

If you have fixed the problem at this point you have done well and have no need to read on.

Toyota services are unaware of this problem because they cannot find this problem as it does not come up as a fault through the vehicle computer, it comes up as the alarm being activated  (which is not a fault).

The following is currently an ongoing investigation of mine but may be worth you looking into?

There was mention that the “Integrated Relay Box” may need to be replaced?

This can control various things including the fob security alarm access to the vehicle and various other security alarm options, this may lead to your problem? 

I have not seen any confirmed results from people whom may have replaced this IRB, so if you still have the vehicle and replace the IRB, could you please post your results?

If there are others whom are reading and have had successful results by replacing the Integrated Relay Box, please post.

i hope this helps…
