B1BB8-SRS WARNING INDICATOR STATUS MISMATCH

For a complete wiring diagram Refer to the Wiring Information.

- When Monitored:
After the Instrument Cluster bulb check is completed, the ORC compares the lamp request by the ORC (On or Off) and the Lamp On request by the Instrument Cluster (On or Off) Can bus messages. Each message is transmitted one time per second or when a change in the lap state occurs.

- Set Condition:
If the lamp request by the ORC (On or Off), and the Lamp On by the Instrument Cluster (On or Off), messages do not match, this code will set.
