Hello everyone, was working on a 2013 acura tl and the factory alarm after locking car would go off about 2 minutes later. Checked live data and all door, trunk, and hood switches are receiving data as per the live data on scan tool. The weird thing is locking the car with the emergency key from inside the remote on the physical door lock, the alarm will not go off. The only history I got was a battery replacement few months ago and alternator a couple of months ago, and this alarm issue started about 2 weeks ago. Any input would be great. Thank you. No DTC'S either.
Check the fuses and relays for the alarm. Then check the wiring.
Ok, thanks, but would that not show up on live data?
Live data shows all doors and locks on/off as it is supposed to be and all working fine including trunk and hood.
An OBD2 scanner cannot show live data for fuses and relays. You'd have to check that with a multimeter.
You're absolutely right but I see the door open, door closed, lock, unlock, and all other functions on live data, if fuse was burned I would not get any feedback from switches and modules would not be available on the scanner. So besides door switches, trunk and hood, or battery spikes what would set the alarm to go on every like 2 minutes. It's driving me crazy but if I use the physical emergency key to lock door the alarm does not go off, only happens when doors are locked with the remote or proximity button on handle. Thanks
