Conditions Requiring Programming

Whenever the battery is disconnected, the Engine Control Module (ECM) adaptations are reset to a "Green" ECM condition. In this condition, certain functions of the ECM are inhibited, and the ECM must relearn these functions. To enable the ECM to do this, the vehicle will have to perform some maneuvers which it may or may not do during a normal road test. This routine should be carried out at Pre-Delivery Inspection, and after any emissions related repair work involving the disconnection of the battery.
