B1203-SRS WARNING INDICATOR CIRCUIT/PERFORMANCE

For a complete wiring diagram, refer to Wiring Information.

- When Monitored:
With the ignition on, the Occupant Restraint Controller (ORC) monitors the CAN B bus for a message from the Instrument Cluster containing the airbag warning indicator status. The ORC requests the warning lamp status from the Instrument Cluster once every second.

- Set Condition:
This diagnostic trouble code (DTC) will set immediately if the indicator status is LOW or HIGH.

WARNING: Maintain a safe distance from all airbags while performing the following steps. Failure to follow these instructions may result in possible serious or fatal injury.

8. Wiggle the wiring harness and connectors of the related airbag circuit or component.
9. If only stored codes return, continue the test until the problem area has been isolated.
10. In the previous steps you have attempted to recreate the conditions responsible for setting the active DTC in question.
