Normal Operation
The restraints control module (RCM) monitors all the deployable devices for a cross link between the circuits of another deployable device. If the RCM detects a short between the circuits of the driver side air bag module and another deployable device, it will store a diagnostic trouble code (DTC) B1047 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 the driver side air bag module and another deployable device can be caused by:
- damaged wiring, terminals or connectors.
- a faulted RCM.
