Q7-Q8:

Normal Operation
The restraints control module (RCM) monitors the resistance of the driver air bag ignitor by measuring the resistance between RCM C310a pins 1 and 2. If the RCM detects low resistance between these pins, it will store a diagnostic trouble code (DTC) B1934 in memory and flash lamp fault code (LFC) 19 (or higher priority code if one exists) on the air bag warning indicator.

Possible Causes
Driver air bag low resistance could be caused by:
- a faulted clockspring.
- faulted wiring, terminals or connectors.
- a faulted driver air bag module.
- a faulted RCM.
