SOURCE: Hi, problem with AU falcon
The horn souds to alert you to the fact that the vehicle has not locked correctly, this is normal. The cycling of the door locks is a common fault. Inside the door actuators there are two switches which tell the control unit when the doors are locked or unlocked. If you issue a lock command (from the remote) and the control unit does not receive the correct signal from these switches, the control unit unlocks the doors and sounds the horn. Disconnecting the door actuators has the same effect as this prevents the door lock sensors from sending the correct signal to the controller. So, the cause is usually one of the door locks has been contaminated with water and the contacts have corroded. You cannot disassemble the door actuators to clean the contacts, you can only replace the entire actuator. Water (usually from rain) gets past the window seal, drips onto the lock mechanism and then runs down the actuator rod and into the actuator. It then sits in the bottom of the actuator damaging the contacts. Now, its usually the drivers door actuator as this is the door and window used the most but, If any of the windows have been left open or partially open, water will get into the actuators causing this problem. If the vehicle has been involved with the floods, the same can happen. Replacement is quite simple but make sure you get the rivets which hold the actuators inside the door as using nuts and bolts is very difficult and may foul on the window as it winds down. Remove the door fittings and the inner door trim, cut the seal in a manner which allows you to reseat it and wind the window all the way up. Disconnect the wiring harness to the lock and drill out the rivets. carefully remove the linkage rod and dont break the clip. Fit the new actuator to the linkage and connect the wiring again. Hold onto the actuator and cycle the door locks holding the courtesy lamp switch in. If all is well, the doors should now lock correctly. If all is well, refit the actuator with the new rivets and refit the door seal and trim etc.. Done..
