Active Codes
An active trouble code indicates an on-going malfunction. This indicates that the defect is currently active every time the ACM checks the particular circuit or function. It is impossible to erase an active code; active codes automatically erase themselves when the cause for the code has been corrected.
With the exception of the warning indicator trouble codes or malfunctions, when a malfunction has been detected by the ACM, the Airbag warning indicator is illuminated for a minimum of 12 seconds, or as long as the malfunction is present.
