The theft-deterrent system operates the theft-deterrent horn and hazard warning lights if a door, trunk lid or the hood is improperly opened.
An answer-back function has been adopted which allows visual verification of the theft-deterrent system operation.
Signal input/output of the theft-deterrent system is controlled by the rear body control module (RBCM).
The rear body control module (RBCM) performs theft-deterrent system fail-safe. (See REAR BODY CONTROL MODULE (RBCM).)
When a locking operation is performed using the remote transmitter is in stand-by preparation mode, stand-by mode, the hazard warning lights flash once.
When an unlocking operation is performed using the remote transmitter is in initial mode, the hazard warning lights flash twice.
NOTE:
The operation conditions of the theft-deterrent system alarm differ depending on the part number of the rear body control module (RBCM).
