Learning Ability

CONTROL MODULE LEARNING ABILITY

Notice: Since the VCM is located under the hood, its connectors are sealed and cannot be backprobed as in the previous model years. Do not attempt to backprobe as a connector or seal damage could occur.

Notice: The VCM must be maintained at a temperature below 85°C (185°F) at all times. This is most critical when the vehicle is put through a paint baking process. The VCM becomes inoperative if its temperature 85°C (185°F). It is recommended that temporary insulation be placed around the VCM or removed from the vehicle during the time the vehicle is in a paint oven or other high temperature process. Do not operate the vehicle if the insulation is on the VCM.

The control module has a "learning" ability which allows the control module to make corrections for minor variations in the fuel system in order to improve driveability. Whenever the battery cable is disconnected, the "learning" process resets. The driver may note a change in the vehicle's performance. In order to allow the VCM to "re-learn" to drive the vehicle at part throttle with moderate acceleration. The vehicle may also operate at idle conditions until the normal performance returns.
