Normal Operation

The restraints control module (RCM) monitors the safety belt buckle switches for a cross link between the feed circuits of the safety belt buckle switches. If the RCM detects a short between the feed circuits of two safety belt buckle switches, it will store a diagnostic trouble code (DTC) B1053 along with the DTC of the component it is cross linked to in memory and illuminate the air bag indicator.
