Normal Operation

The restraints control module (RCM) checks all of the safety belt pretensioners for faults. If the RCM detects a low resistance or open on the driver safety belt pretensioner circuits, it will store diagnostic trouble code (DTC) B1877 or B1885 in memory and illuminate the air bag indicator.
