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 the safety belt buckle switches, it will store a diagnostic trouble code (DTC) B1052 along with the DTC of the component it is cross linked to in memory and illuminate the air bag indicator.

Possible Causes
A cross link fault between safety belt buckle switches can be caused by:
- damaged wiring, terminals or connectors.
- a faulted RCM.
