Normal Operation
The restraints control module (RCM) checks all of the passenger air bag module circuits for faults. If the RCM detects an open or low resistance on the passenger air bag module squib 1 circuits, it will store diagnostic trouble code (DTC) B1933 or B1935 in memory and illuminate the air bag indicator.

Fault Conditions
The RCM monitors for the following fault conditions:
- circuit open.
- low resistance.

Possible Causes
A passenger air bag module squib 1 circuit open/low resistance fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulted passenger air bag module.
- a faulted RCM.
