High idle speed, stalling or other driveability symptoms may still be present after a defective component has been replaced. This may mean that the
Adaptive Strategy must be reset in the EEC IV processor. The reset procedure should be performed for any of the following reasons:
^
On new vehicles.
^
When the battery has been disconnected during normal service.
^
When an EEC component is replaced or an adjustment is made. (Example: Hard Stop RPM)
The procedure to reset Adaptive Idle Speed Control is as follows:
1.
Disconnect battery for 10-15 minutes.
2.
Reconnect battery, start engine and bring to normal operating temperature (upper radiator hose hot and pressurized).
3.
Set parking brake and place foot on service brake.
4.
Place transmission in Drive (ATX) or Neutral (MTX), steering in the "straight ahead" position.
5.
Place all accessories in the Off position. A/C Off and the mode selector lever, located on A/C panel, set in the "floor" position.
6.
When the engine RPM reaches the Adaptive Idle Speed (refer to the following application chart), let the engine idle for 2 minutes.
NOTE:
The vehicle can be driven to check for customer concerns. This will start the learning process for Adaptive Fuel Control.
