Few months ago the SUV sustained a front end damage, and prior to taking it to a body shop, I noticed that when arming/disarming the car, the lights will flash without beeping. At that time, I thought maybe the horn was out of commission from the wreck, but it turn out to be working as expected.

Upon taking the vehicle from the shop, I observed no light flashing/beep upon flashing lights but I still get the light flashing when disarming the car. Furthermore, I tried to follow below link, but unfortunately I didn't see any option under system that will allow to turn on/off beep/flash.

Thanks a mill for your support!
