B1203-SRS WARNING INDICATOR CIRCUIT/PERFORMANCE

For a complete wiring diagram refer to Diagrams/Electrical.

- When Monitored:

With the ignition on, the 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 DTC will set immediately if the indicator status is LOW or HIGH.
