if your check engine light comes on with one of the following codes, P020A, P021A, P060C, P2048, P207F, P2263. there is a ecm programming avail but the check engine light (must) be on with the following codes stored. don't go in and ask for the reprogram if the light is on not because Nissan will not program your ecm.

It's a ECM reprogram. Changes the parameters of the input data of the sensors. However most trucks have the newest data already installed. If you do get one of those codes take it in, we can do the update.
