Active Codes

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 or has occurred in that ignition cycle. This means that the malfunction is currently there every time the 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 or not present in the subsequent ignition cycle. 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.
