Stored (Intermittent) Code: Notes
A diagnostic trouble code that is not there every time the TCM checks the circuit or function is a Stored (Intermittent) code. Problems that come and go like this are the most difficult to diagnose, they must be looked for under the specific conditions that cause them. If the DTC is reset (after an ignition cycle) the DTC will be set to Stored (Intermittent) status. A DTC status can be "Active" or "Stored" (Intermittent). Active is when the DTC is present in the controller and the transmission is in the particular mode of operation for that DTC. Stored means that the DTC occurred at some point, but is not currently present, or the conditions have not been right to check for the presence of the problem, when a DTC is classified as Stored (Intermittent), no TCM reaction is required.
