Active Codes
WARNING: This page is about a different car, the 2003 Dodge Intrepid, 2003 Chrysler Intrepid, 2003 Chrysler Concorde, and 2003 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
The code becomes active as soon as the malfunction is detected or key-off, whichever occurs first. An active trouble code indicates an on going malfunction. This means that the malfunction is currently there every time the airbag control module checks that circuit/function. It is impossible to erase an active code; active codes automatically erase by themselves when the reason for the code has been corrected.
With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is detected, the airbag lamp remains lit for a minimum of 12 seconds or as long as the malfunction is present.
An "Interrogate Right SIACM or Interrogate Left SIACM" diagnostic trouble code indicates an active trouble code in the respective module.
