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 seat side air bag module and another deployable device, it will store 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 seat side air bag module and another deployable device can be caused by:
- damaged wiring, terminals or connectors.
- a faulted RCM.
