Control Module Learning Ability

The control module has a "learning" ability which enables the control module to make corrections for minor variations in the fuel system. This learning ability can improve driveability. Disconnecting the battery resets the learning process. A change in the vehicle's performance may be noticed when a reset occurs. The vehicle operator can teach the control module in order to regain some of the lost vehicle performance.

In order to teach the control module, ensure that the engine is at operating temperature and drive the vehicle at part throttle with moderate acceleration. The vehicle may also be operated at idle conditions until normal performance returns.
