Active Codes
WARNING: This page is about a different car, the 2001 Dodge Viper and 2000 Dodge Viper. 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 defect 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.
