Engine-control association
An engine control module manages engine operation using sensor inputs and programmed control strategies. Depending on the vehicle, it can regulate functions such as fuel injection, ignition timing and emissions controls. Those functions affect how the engine runs and how it responds to driving conditions.
The association of 89663-30682 with engine-control software is tentative. The identifier alone does not establish a specific vehicle application, the behavior of this calibration or a change made by this revision.
