I searched but found nothing.

I need to know what fuse or wire to pull to disable a malfunctioning factory RKE alarm system that is discharging the cars battery over night(s).

A more elegant solution to my problem may be to disable the alarm from automatically activating when the drivers door is key locked.

Found in the Owner's Guide a procedure for "Radar Sensor Mode Off" that might cure the root cause of the problem.

More: Testing the radar sensor off mode to see if this stops the false alarm trips, amp draw readings from the battery suggest it's not a bad alternator or stuck relay. Disconnected horn from the alarm years ago due to the false alarms.

 

Radar Sensor Mode Off worked to fix the false alarms and battery drain, All has been OK since the reprogram sequence.
