Circuit not configured.

System reaction to a fault:

•	The airbag system should be considered non-operational. There may, however, be some functionality.

•	The control module ignores the activation command from the sensor as long as a fault is active.

Checking the wiring harness

Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.
