Engine control role
An engine control module uses sensor readings to calculate how the engine should run under changing driving conditions. Its calibration contains settings used in those calculations, affecting behavior such as starting, idle and response to the accelerator. These are general functions of the controller family, not documented changes specific to this revision.
The identifier alone does not establish a particular vehicle model, engine or compatibility. The full calibration number and filename are useful for distinguishing this record from other Toyota firmware entries.
