HI Guys Hope you can help me out with this one. Last night for no apparent reason, alarm began flashing with low key siren for about five times ,then stopped for about 30 minutes then started up again, Eventually about 3am decided to investigate but nothing to see, alarm continued to activate over set period for a short time then stopped, prior to flashing again about 30 minutes later.
The only way around it was to deactivate alarm through key fob, and then lock car using key only which is the position we are in at the moment?
At the back of my mind I seem to think this is something to do with a low battery…So advice really appreciated Thanks
No unfortunately nothing like that…its really puzzling, the car is a 2010 power shift purchased new has only 11000 on the clock. Never had a problem with any item on the car and can find no information as to what could cause it.As stated it began in the early hours of the morning, flashed for 5 times then switched off, only to repeat 30 minutes later and so on.
The car is till under lock and key restraint! Placed a charger on the battery but it came up fine??? really baffled over this one.
I had a Civic Type R a few years back that developed something similar, started happening during the first cold weather of Winter. Turned out to be a duff internal ultra sonic sensor and was replaced as a known issue.
Strange though if you’ve had the car several years and only just started - but worth checking? Is there a way to diagnose which sensor is triggering the alarm?
After three nights of turning off alarm and locking with key, finally discovered wife had mislaid works mobile!!Carried out a call search and sure enough her phone was ON and jammed down the side of the passenger seat directly alongside interior alarm sensor.
Phone removed, problem solved!!! many thanks for hint in the first place…Moral of story turn off phone or stand by for an early morning alarm shout!!!
