When Monitored & Set Condition
When Monitored: With ignition on, the ACM monitors the PCI Bus for a Left SIACM status message containing the airbag warning lamp "On or OFF" request. The status message is sent to the ACM once each second or upon any change in the active DTCs.
Set Condition: The Code will set, if the ACM receives an Lamp On status message from the Left SIACM. NOTE: This indicates that there was an active diagnostic trouble code in the Left SIACM.
